MacBook Air charge plug light not working

According to a tech who works at a local Apple repair center it happens mostly on older plugs. But on newer and current plugs it's also not unseen.

Usually unplugging plugging back the magsafe fixes the problem. If not the problem is usually fixed once the computer is powered off and the plug is reconnected.

Personally I have seen this on most of my macs. It never bothered me much. But on one of them this used to happen all the time until the battery was replaced.

Usually the problem is the green LED being turned on instead of the amber LED during charge. But there are occurrences of none of the LEDs showing during charge.


Artifacts when viewing pdfs in Preview (and Skim)

The first, simplest step for troubleshooting even an Apple app that is acting up is to quit it and delete its preference files. There are some utilities that check the validity of preferences files and delete corrupt ones. Easier still is to move them to the trash from your
User Library at ~/User/Library/Preferences
or the Main Library at HardDisk/Library/Preferences. The application will rebuild a fresh set next time you open it.

(Note I am not referring to the Library within the System Folder.)

If there are complicated settings you might want to remember, make a sticky first!

The second step is often to download or otherwise install a fresh copy of the application itself. It's surprising what both these steps can accomplish.


How to fix a MacBook's sound output which is stuck on headphones?

Try getting some compressed air at Wal-Mart or Best Buy or another retailer and blow the headphone jack clean with that. A can will cost about $5 and you'll need to be 18 or older to buy it.

If it still doesn't work after that, the headphone jack will likely need to be replaced. Unless you do electronics repair, find a professional to replace it for you.


Open With - Change All reverts back to original application CS5/CC

It's expected behaviour.

There is only one creator type shared by both versions, so the system will always choose the newest version.
You can probably see it better if you try to change it using RCDefaultApp. It will only offer the newest installed version of valid apps in the drop-menu for any file type.

Deleting a key will set it back to its default value.

However, you don't even need to delve into defaults to make this change, to or from analog — it's in the UI: System Preferences → Dock & Menu Bar → Clock → Time Options.


Exponential CD burn times in iTunes 10.6.1 (7) on OS X 10.6.8

According to Wikipedia, the original playing time of an audio CD is 74 minutes.

Longer play durations are achieved by "squeezing" the data tracks closer together. Also, because CDs are written from the inside out, the write speed is much faster on the outer sides of the disc — bigger diameter means more distance travelled in the same time.

So squeezing plus faster writing needs more precision. It’s likely that an older CD writer will struggle (on a pre-OS-level) with the precision requirements, leading to claims of absurd burning times. I think you will be on the safe side when burning shorter CDs. I hope this helps!


Looking at the link and also your path it looks like you have installed Macports. Its installer will change in ~/.profile the path but not in the way you show. See macports document for the correct way to do this.

Editing /etc/profile is not the correct way as it affects all users and is also more complex to deal with as requires root permission and is also an Apple supplied file that could be changed in Apple system upgrades

This explains two of your /opt/local/bin ... etc in your path (/etc/profile and ~/.profile) More and the PATHnexport imply that yor editing of files has gone wrong.

I would restore /etc/profile from a backup to be as Apple set it up, and check that .profile has the lines as per the macports document. Also check to see if you have ~/.bash_profile or ~/.login and check they do not have any alterations to the PATH

If you are not used to Terminal (e.g. if you do not understand what these .profile files are) then it mght be better to install wine via a GUI method e.g. Wineskin or Crossover (Even if you do understand Terminal and shells t is easier to use these)

Airport Extreme to 3 Sony Airplay speakers

Can you connect multiple Sony Speakers?  Yes.  Why wouldn't you be able to?

The AirPort Extreme is just like any other WiFi router in as much it is a router, a switch, and a WAP (Wireless Access Point) like any other wireless router.

The Sony speakers are just like any other WiFi speakers in as much they are clients on a WiFi network.

The real question here is does iOS support streaming to multiple AirPlay speakers simultaneously?

Currently, the answer is NO.  This is a limitation of iOS.

However, there is an App called Airfoil Satellite which gets your around this limitation.


In general, no. The game developer can store progress on the device locally, on an iCloud / Game Center log in basis (or both) or save data off on a private server / public cloud.

It really depends very specifically on how the game was programmed to behave and you’d need to contact each vendor / read their documentation or experiment to understand how or if game progress and data persist on iOS.

Even deleting an app won't remove some game data and some people love that and others, not so much.

Can I delete an iOS game and retain my progress?


"Failed to check receipt hash" after switching to a new computer?

I think you have to redownload those apps from the App Store in order to get new receipts that match your new Mac.


How to get UTF-8 locale when connecting via SSH to MacOSX from PuTTY (Windows)

Solved my problem using Stack Overflow question: https://stackoverflow.com/questions/7165108/in-osx-lion-lang-is-not-set-to-utf8-how-fix

The most important part of the answer:

  Try adding or editing the ~/.profile file for it to correctly export

How do I change the profile picture in iTunes 12?

Simply put: No, you can not change it.

This is because Apple has designed it that way, and the only way of doing it would be going into the iTunes files, and if you're lucky and find an uncompressed image and just changing that one.

Otherwise, sorry but it isn't possible.

Help with a HD reformat and Mountain Lion reinstall due to unknown type of hack, Malware, etc

This sort of infection is extremely rare in the OS X world. Getting reinfected over and over again is  even less likely. Not saying it's impossible, but very unlikely.

I would start by installing Little Snitch and setting it to monitor outgoing connections. Also monitor your launchd folders using http://www.circl.lu/pub/tr-08/

The first step I would recommend is changing all of your passwords and using something like 1password so your ex can't get into something again.

Marking this as a wiki so others can add suggestions since this isn't an "answer" per se.

[2013-04-14: There's also Radio Silence which is an outbound filter like Little Snitch but supposedly simpler and less "chatty".]


Numbers - continuous line connecting gapped data?

You should plot the data using the 2d Scatter plot. This will draw a continuous line connecting the dta points.

I had some issues with scatter plot in Numbers but eventually got it working. I had problems sometimes getting to to use the correct x and y values. Maybe you won't encounter these issues.


Why would native Mac filesystem performance be MUCH worse than various virtualized disks on the same mac?

What you are seeing is the consequence of your hypervisor lying to you about disk write flushing, presumably because you have disk writeback caching enabled in the VM configuration. Disable the write caching, and you will find the performance is going to be much more similar (probably worse than bare metal).

As a secondary test, you can try on your host by LD_PRELOAD-ing libeatmydata and you should see that your bare metal performance reaches or surpasses the performance in VMs.


Can we setup a local HTTPS Server in Mac OS X using swift

Yes, Apple's Swift language can be used to create a web server that accepts HTTPS connections. See Going Server-side with Swift Open Source for Apple's introduction to developing servers.

Using Swift, you have access to a range of included and third party SSL/TLS libraries. The language used to write the library is not important, so long as the library offers a C API.

Network.framework and AFNetworking

If you are a developer, consider using Apple's Network framework. The framework claims to provide easier support for secure connections.

Alternatively, look at using the open source project AFNetworking.

Apple's Frameworks

Given you want to focus on Apple's security offerings, you can pick from:

Apple's Network.framework (in beta at the time of answering)
Apple's NSURL* family of classes
Apple's CFNetwork
Apple's Secure Transport API

Be aware that most of these are ultimately built upon the low level Common Crypto code base.

Transparent Proxy

Consider using an existing web server, such as Nginx, httpd, or Caddy, to act as a transparent proxy in-front of your own service. The existing web server can handle the SSL/TLS security and pass back HTTP requests to your locally running service.

This is a fairly common configuration because it simplifies your service and puts the security burden on a well tested existing front-end server.

Not a developer?

If you are not a developer, consider using a pre-built web server with support for Lets Encrypt (free) TLS certificates. One such server is Caddy:

  Caddy is the HTTP/2 web server with automatic HTTPS.

Voice Memos visible on iTunes, but files appear to have been deleted on iPhone. Can I recover?

so sorry that this happened to you. Indeed, iTunes is probably listing the voice memos from the plist file - if you haven’t found the recordings themselves with iFunBox (.m4a files), they are probably lost unfortunately. You can have a look again in Media/Recordings and hunt for these if you haven’t already.

Sorry I can’t help more.

The display contrast on my new iMac (the Retina 4k 21.5" model) is too high. Can it be lowered past the lowest setting?

Yes - by using display profiles, you can alter what absolute values the relative 100% and 0% contrast settings are. You don’t even need calibration hardware, but sometimes that helps you dial this in precisely.

Go to the "Color" tab of the "Display" panel of System Preferences
Select the display profiles, one by one to see which you prefer.

When I got to "SMPTE RP 431-2-2007-DCI (P3)," I hit PAYDIRT: contrast and saturation were down to something I could easily live with.

Functionally speaking, where will I see a difference between dual- and quad-core i7s?

The analogy is the choice between having two really fast employees, or having four quick ones. If not a lot is going on, the two fast ones will be tearing things up. But if things are busy, and a lot is going on, having twice as many will really show up.

Note that with the i7 Quad Core, if you need a lot of speed from one or two cores, you can get it through the Turbo Boost.

I would lean toward as many cores as possible, because I like to have lots of programs open and be switching in and out. If you like to work on one thing at a time, and if those things aren't all that compute intensive, it may be a harder decision.


Deauthorise Apple ID from the Mac App Store

You will need to delete Xcode, sign out of the Mac App Store, sign in with the new ID and "buy" Xcode again from the Mac App Store.


In iTunes, is there way to switch easily back and forth between tracks in two different playlists or library parts (say podcast and music)?

It sounds like you are referring to something like a Smart Playlist. Smart Playlists organizes your songs more, based upon song type, last listened to, skip count, etc.

The point is to quote the echoed message.


How can I enable Personal Hotspot on iOS 7 even though my carrier has disabled it?

If you're willing to jailbreak, you can use TetherMe. It will enable Personal Hotspot then change the location of the data to appear to be coming from inside the device, thereby bypassing the carrier's disable.

 TetherMe
Dynamically enables native tethering or personal hotspot for iOS3.X or newer devices. This should work on any carrier without the need for customised bundles or preferences.
TetherMe has been tested to work on all iOS versions from 3.0 to 6.1 and works by telling the iPhone to allow tethering on any APN that is used for iPhone data. As a result, you should not be charged any more for tethering data than normal data by your phone company as all tethering data appears to come from the phone itself.

As a general rule, which sound input device is used is controlled by the OS in System Preferences > Sound > Input (as shown in the second image below) and some, but not all, apps one can choose a sound input device other than the one set for the OS. For example, in Audacity you can select other than the one set for the OS.

However, I am not aware of a built-in preference in Safari that lets one choose a sound input device. There is a microphone setting in Safari, but it doesn't offer control over which sound input device to use.

Have a look in: Safari > Preferences > Websites > Microphone


Mid 2011 iMac 27'' won't boot - 3 beeps and maxed fans

Upon pressing the power button, I’m greeted with 3 beeps every 5
seconds. After around 35 seconds all the fans are maxing out on top
speed.

There's a RAM issue.
3 successive beeps followed by a five second delay, then repeating means "RAM didn't pass an integrity check.  Apple has an excellent support document that details the startup sounds:  About Mac startup tones
Normally, this would be limited to the...

RAM Modules
Memory slots (logic board)

To diagnose this, you want to remove all of the memory and try each module in each slot individually.  The idea isolate whether it's a memory module problem or an issue with the slots on the logic board.  You should get one of the following results:

If one or more modules gives you an error in every slot, it's that/those modules.

If all modules give a problem in one or more slots, it's that slot
(Draft)

If you can't narrow it down to one of those two possibilities, there's a "larger" issue that needs to be investigated.

Cause:  CPU Issue

I had removed it [CPU] the first time round to repaste it. The thought process was that the iMac was almost 10 years old and had never been repasted.

In this case, this is where the issue occurred.  Intel CPUs directly connect to a number of peripherals like display and memory.  (A memory buffer actually, but for all intents and purposes, it's directly connected to the memory modules).  As you can see from the CPU block diagram, there are items that directly talk to the CPU, like the memory, and others talk to the CPU via the Intel Mobile Chipset.  The chips that got bent just so happened to be associated with the memory of the system.
Carefully bending the pins back to being straight should fix the issue.
Going forward, while I do wholeheartedly that computers (not limited to Macs) need periodic maintenance that includes replacing the thermal paste between the CPU/GPU and heat sink components, care must be taken when doing this.  You shouldn't need to to remove the processor(s), but should it be necessary, extreme care should be taken.


My iphone 5's language in settings is set in english but it types in Chinese in Messages, google etc?

From Apple's support article: https://support.apple.com/en-us/HT202178

Change the language
If more than one language is on, you can change the language while typing.
Follow these steps:

Tap  to choose the next language on your keyboard. The chosen language appears on the Space bar.
Touch and hold  to display a menu of enabled keyboards. Drag to choose a new keyboard.

In iOS 6 and later, the language of the keyboard determines the language of the dictionary, if one is available for the language.


How can I hide the Biography and Similar Artists panel in iTunes?

I have yet to update my iTunes (and now I'm starting to think I should avoid it all together!) I was, however, able to search an Apple discussion board and found this to be the closest fix (hopefully) to what you are asking for:

Go to Edit>Preferences>Parental>Check the Apple Music Connect>Restart iTunes.

Apparently this user has a PC but they said they assume it will be easy to do on a Mac as well.
Here's the link to the discussion board I referenced. Hope this helps!


To set JAVA_HOME, you should use

export JAVA_HOME=`/usr/libexec/java_home -v "1.7*"`

or

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home

currently you  did not use export on the variable. Environment variables that are set without the export command will not be inherited in the environment of the commands you are calling, so it would not be read by Java.


MacBook Pro (Late2011) fails to boot and repair HDD volume:

The error that you are seeing, Incorrect number of thread records, means that there is a problem/corruption in the HFS catalog.

The Catalog File is another B-tree that contains records for all the
files and directories stored in the volume. It stores four types of
records. Each file consists of a File Thread Record and a File Record
while each directory consists of a Directory Thread Record and a
Directory Record. Files and directories in the Catalog File are
located by their unique Catalog Node ID (or CNID).
A File Thread Record stores just the name of the file and the CNID of its parent directory.

The Fix...
First and foremost.... you do have a (Time Machine) backup, right?
Next, (personally) I wouldn't repair this HDD.  I would get an SSD drive (see this answer for reference), do a clean install of macOS and then migrate your data back over.
Can you repair it?  It's possible.  It's unlikely that Disk Utility will have the capability of fixing it so you will need something like DiskDrill or DiskWarrior.  Even still, you are fixing a 6+ year old drive which is now outside it's useful life.
If the drive is still good (physically) but you can't repair the volume, you could format and reinstall macOS, but if this is the route you have to take, I would go with an SSD upgrade; thus my initial recommendation.


Builtin VNC stops working after waking headless Mac mini from sleep (black screen)

and restart your mac. Mountain Lion forces me to enter password twice but it wakes up and works.


Going back to Mavericks: will i lose my files that I have created on Yosemite?

Going back to an older TimeMachine backup will make your other files deleted.

You will have to backup them to another place where you can later access them, because using TimeMachine is kinda like using well.. A time machine.


Is there a repeating, vibrating timer app for the iPhone that supports app-switching?

You may be able to craft your own solution with a combination of scripting software and assistive hardware.

Assistive hardware exists to track head movement. Most assistive hardware can be used to provide an input that can then be scripted via AppleScript or shell script.

A few examples are linked below. I have no experience with these tools but your goal appears possible.

Headmouse

  HeadMouse® Extreme replaces the standard computer mouse for people who cannot use or have limited use of their hands when controlling a computer or alternative and augmentative communication (AAC) device. The HeadMouse translates natural movements of a user's head into directly proportional movements of the computer mouse pointer, so as the user moves their head the mouse pointer on the screen also moves.

SmartNav

  The SmartNav 4 AT is a total hands-free mouse solution. With built-in Dwell Clicking Software and a free On-screen Keyboard created by Lake Software. The AT package is used successfully by people with ALS, spinal cord injuries, muscular dystrophy, and other special needs.

One Switch

One Switch sell a wide range of assistive hardware and link to associated software.

  The following list details a number of different styles of head, mouth and eye operated controllers. Most of these are for PCs and Apple computers, but there are alternatives for games consoles too. Some of these devices are very expensive, so it is always worth trying to track down some way of trying before you buy.


How to move my Photos library to internal drive to use iCloud Optimize space feature

Once your album shows as fully synced with iCloud, simply quit Photos, disconnect your external drive, run Photos, and tell it to create a new Photos Library on your internal drive. Photos will download all thumbnails and the high res versions of images you view regularly.


"APFS Container Resize error code is 49153" when adding MS-DOS (FAT) partition

Select MS-DOS (FAT) from the pull down menu, correct the name of the partition as necessary and press Erase:

This will replace the APFS container with a FAT partition.


Connecting Canon CanoScan FS4000US USB Scanner to Mac OS 10.7.5

Have you tried installing this comprehensive Apple Canon Printer/Scanner driver set?

I bought iPhone 7 a few days and got exactly the same problem. My old iPhone 5S still syncs perfectly but new one doesn't.

Have done everything: logged out Apple ID and in again, turned off iCloud Notes syncing and then on again, still nothing. Even set my new phone up as a new iPhone but the Notes app is still not syncing with other devices where it works perfectly. I can see notes made on other devices but edits made on iPhone 7 are not showing up on my old iPhone, iPad and Macbook Pro.

Use `security` to get my login username and password for use in shell scripts / cron

I don’t believe that the Security framework keeps a two-way copy of your password. The best you could do is use a keychain pair as you’ve stated and then have your script check if that password is able to be locally authenticated before trying it over the network. That way at least you get an alert every few months to update your Keychain.


Why Time Machine can't make first copy if lid is closed?

When you perform an initial Time Machine backup, it is making a backup of everything which may (read that as more than likely) take a long time.  Subsequent backups are only files that have changed and these are, most often, very small changes.

Your first backup
The first time you back up your Mac with Time Machine, it might take a
long time to complete. This is because Time Machine copies most or
all of the data on your Mac to your first backup. You can keep using
your Mac while Time Machine works in the background to back up your
data.
After the first backup is complete, Time Machine works in the
background to back up only files that have changed since your last
backup. This means your next backup is usually faster.

When your Mac is sleeping with Power Nap enabled, Time Machine backups are attempted at 1 hour intervals.

Time Machine backups are attempted hourly until a successful backup
has been completed.

This interval based backup is designed to backup the minor changes.  The first backup is much, much larger and requires more resources. This also tells you why after 10 minutes it "failed" - it's an hourly process.  Remember, you're putting it to sleep, meaning it's not going to run at full speed until it finishes something; it's going to going to attempt things at regular intervals until it either done or it wakes up.
If Apple is advising you that you don't put your Mac to sleep during your first backup, you should heed their advice.


Software to emulate Windows 7 on OS X, for developing

I'm a Fusion user and have been for a few years now. Fusion 4.x has been a nice upgrade and it's a very stable way to run the latest Windows OSes on OS X. I think you'll be fine with Fusion or Parallels -- both are tested and support Win7. VirtualBox is a nice option, but be prepared to go it alone if you run in to any issues.

None is really better than the other in my opinion. They all have some overlapping features and they all have some features that are unique to the product. Try before you buy if you can.

I will comment on your system: you're going to find things running slow with only 4GB of RAM and a Win7 VM for development work. Visual Studio is a pig and it's running on top of an OS that's not terribly great at memory management. I'd recommend you upgrade that 4GB to 8GB (or more if your model supports it) if you want the best virtualized OS experience.


It look like the old iSync App icon - the iSync App was AFAIK removed in OS X Lion.


Messages.app on macOS won't send/receive/display messages to/from one specific contact

I just switched from my old MacBook Pro to a new one, and I didn't even think that I'd need to do something like this.  Still not sure why it affected just this one user, but after doing this, the problem was resolved.


I have photos on my phone that I can't delete

Assuming you have an iPhone; probably best to backup your phone through iTunes then do a factory reset and restore your data. If they are ghost/misbehaving photos then they won't be included in the backup and hence won't be restored back onto your phone.


How can I find the intersection of two lists in AppleScript?

The List & Record Tools Scripting Addition provides intersection of listA and listB (among other bits of terminology).

There is no built-in “primitive” for computing a list intersection. Usually one would just use one or more loops to check each element of one list against the other. This can be simplied (and sped up1) a bit by using one of the is in/is contained by/contains operators (or a negation thereof):

set listA to {"red", "green", "blue"}
set listB to {"green", "blue"}

to intersection of listA against listB
    local newList, a
    set newList to {}
    repeat with a in listA
        set a to contents of a -- dereference implicit loop reference
        if {a} is in listB then set end of newList to a
    end repeat
    newList
end intersection

intersection of listA against listB --> {"green", "blue"}

1The is in operator and its relatives are implemented by the AppleScript runtime environment in lower-level code where they execute much faster than the normal interpreted AppleScript code.

Incidentally, handlers that use labeled parameters have a limited set of terms that can be used for the labels. For example, intersection of listA and listB is not possible as a user-defined handler because and is not a recognized label. See the AppleScript Language Guide section on handlers with labeled parameters for a list of valid labels. Applications and OSA extensions can defined their own terminologies (e.g. the List & Record OSAX provides this exact syntax), but user-defined handlers are not as flexible. I usually just use positional parameters (handlerName(param1, param2, …)) instead of trying to make invocations of my handlers look like prose.


I've had this problem before. I think it is because the data is corrupt. What you need to do is restore the drive and create a new one. The easy way is to get a different computer and reformat it there, but if not, don't worry. Just go into Disk Utility and attempt to restore/reformat the drive. If it gives you an error like "Can't unmount the disk", follow this guide to forcefully unmounting a Time Machine backup disk. Then, you will have to setup a new backup.

Note: If your drive still gives problems after this, it may be broken and you may need to purchase a new one.

If you're signing in and don’t have a trusted device handy that can display verification codes, you can have a code sent to your trusted phone number via text message or an automated phone call instead. Click Didn't Get a Code on the sign in screen and choose to send a code to your trusted phone number.

You mentioned that the phone number is still the same, however, the normal SMS option is not working, so I would try the phone call method instead.
There is more information about how to get a verification code and sign in with two-factor authentication available at https://support.apple.com/en-us/HT204974.
Should these options still not work, you can request account recovery to regain access to your account.

Apple Mail doesn't show when a mail is encrypted (using S/MIME)

It is most certainly a bug that needs to be addressed in future versions of OS X.

I have the same problem and have found out the following curiosities:

When I added a rule to change the color of encrypted emails to give at least a visual indication in the list view, it worked fine, so there's really no reason not to show the lock icon.
The moment I added the rule and applied it to existing mails, both the signed and encrypted indications showed properly on the conversation
Upon restarting Apple Mail however, the signed indicator stopped working again on mails that were both signed and encrypted
Furthermore, both indicators stopped working on mails which I have sent
Based on a rough guess, about 50-60% of the encrypted mails now have the proper visual indicator, but only those I've received and not those I have sent.

All in all it's very weird, non-deterministic behavior that I can't explain other than being a bug. It persists in 10.11.5. Mails that are only signed always show properly unless they're also encrypted.

Furthermore, my iPhone seems to have no problem at all, tagging all signed and/or encrypted conversations properly.

I suggest filing a bug report with Apple (which I am about to do now).


How can my iPhone know my location whilst in airplane mode?

If you have a device with iOS 8.2 or earlier, Airplane Mode will also
  turn off GPS.

Thus with iOS 8.3 and above the GPS stays on while in Airplane Mode.

https://support.apple.com/en-us/HT204234

GPS works independently of phone or WiFi signals and is "receive only", so keeping it enabled even in Airplane mode doesn't influence other electronical devices nearby.


How to see compass accuracy and recalibrate the compass in iOS 10?

In troubleshooting this, I learned a few important things:

While there is no way to manually force a recalibration of the compass aside from toggling location services on and off, generally the compass attempts to recalibrate itself when an app requests it if it has not been in use.
The 'blue cone' in maps seems to be the best way to easily tell how accurate the calibration things it is.
Arguably most importantly (and most embarrassingly), my issues were entirely caused by a case that I was using that had a small magnetic clasp in it.  Everything worked just great after getting rid of it.


use `pf` to allow TCP traffic on specific port (from specific subnet)

It's not about precedence; it's logical AND — those firewalls are independent to each other and you're invoking both of them. Even if Pf won't block connections you have specifically verified that socketfilterfw won't pass it.

Update to a specific version of Safari for iPadOS

The version of Safari browser is tied to the version of iPadOS running on your iPad. It's not possible to pick and install a specific version of Safari which is lower than the current latest version of iPadOS.
If you wish to use a specific version for development and testing, you can install Xcode on your Mac, which would give you access to iOS/iPadOS simulators running on macOS.
Thereafter you can pick and download a specific older version of iPadOS (such as iPadOS 13.1).
The only con is that instead of Safari running on a real iPad device, you'd be testing on a software simulator of Safari for iPad running atop a desktop/laptop computer.


You can turn it off by logging in once as the root user. Root's disabled by default, but here's how to enable it and log in as root:

Steps taken from here:
http://www.dreness.com/blog/?p=231

In Finder, choose Go –> Go to Folder... (or shift command g), and enter /System/Library/CoreServices
In the CoreServices folder, open Directory Utility.
From the Edit menu, choose "Enable Root User", and supply a password.
Open System Preferences –> Users & Groups prefpane, and under Login Options, turn off Automatic Login, and set the login window display to Name and Password.
Reboot. Log in as root from the login window. Perform one final heroic click of Memory Slot Utility’s OK button, going for maximum style points.
Log out, log back in as yourself, put settings back the way you like them. I suggest using Directory Utility to disable the root account.


Ribbon tabs in Office/Word/Excel 2011 stop working

After months of searching I found this non-obvious, but very easy workaround on Mac OS X Hints.

While the majority of the tab isn't clickable, the very top edge of the tab is. So just click on its top border.

Still not sure what the underlying problem is, but this much easier then closing and reopening the document.


Applications stop responding when waking up from sleep

You might try seeing if trashing any files that have windowserver in them from ~/Library/Preferences/ByHost/ and seeing if that helps to temporarily remedy the issue.

I would expect this to get cleaned up in an official patch once it's certain these files are causing some of the sleep/wake sluggishness - but I've seen anecdotal evidence that this works for some.


Can't create new directory in home folder: What are "default" permissions/ownership?

The answer was provided by fd0 who posted it on SuperUser.
The problem turns out to be caused by conflicting ACLs, and was solved by removing them all. (Apparently resetpassword as suggested above did not clear these ACLs.  I don't know why.) The terminal command that revealed the conflicting ACLs was:

ls -ledO@ "/Volumes/Macintosh HD/Users/jbenni"

The terminal command that fixed the conflict (by removing all) was:

chmod -N "/Volumes/Macintosh HD/Users/jbenni"

I hope this helps someone else. I was chmod aware, but didn't have a working knowledge of ACLs - so I never would have found this on my own. Stackexchange rocks!


IKEv2 VPN not working after updating to MacOS Catalina - User authentication failed with username authentication settings

I had the same problem and I fixed with changing "Authentication Settings" from "Certificate" to "None".
After this change, you will see 2 new options appeared just below, "Shared Secret" and "Certificate". Select "Certificate" option and reselect the certificate that is already used for the VPN connection before.
Then click Connect button, confirm applying changes and viola!


Taking over old iPhone 4, updated to iOS 6, but can't activate?

All you need is a SIM card in the phone while you activiate it first time after upgrade. (Not sure if sim card needs to be same carrier, still active etc. I was lucky I could borrow a friend's SIM card that incidently was also same carrier as the phone had been on earlier)


Would it be safe to use Ubuntu on an unsupported Mac?

This should be fine.

A mid-2009 MBP won't be seeing any firmware updates from Apple.

If you ever found some reason you needed to run macOS on the machine, you can boot from a USB stick. Consider prepping that USB stick before you switch to Ubuntu.

Linux can definitely help breath new life into an older Macbook. You may want to consider a lighter-weight desktop environment or window mananger to maximize that benefit, though.

Microsoft mouse acting erratically randomly with Thunderbolt to VGA connected?

It seems very unlikely that it should be the case.

It might be possible if the adapter was somehow defective and sends out EMI (i.e. "noise") that is picked up by the USB cable for the mouse. If that is the case, your log should be filled with USB errors. However I do not find this scenario to be likely at all.

Is there a way to hide, stack or collapse menubar icons?

Mac Bartender

I've been struggling with this problem for quite some time as well and I think I've finally found a good solution.

I'm using Mac Bartender which is in free beta at the time of writing. The app has a lot of useful features for cleaning up an overflowing menubar.

For each menubar icon you can choose to:

Display it normally
Completely hide it
Display it in the menubar when Mac Bartender is activated
Display it in the Bartender Bar when Mac Bartender is activated

One thing to note is that it doesn't let you manage the built-in OSX 'menulets' (wifi, sound, spotlight, etc) yet, but that feature is coming according to their FAQ.

Messy Menubar

Clean Menubar

Bartender Bar

From the official site

  Take control of your Menu Bar

  With Bartender you can choose which apps stay in the Menu Bar, are
  displayed in Bartenders Bar or Hidden completely.

  Bartenders Bar

  Can be displayed and hidden as you want, by clicking on the Bartender
  Icon or via a hot key.

  Minimalism

  If you want a really clean look and privacy, Bartender can also be
  hidden.

  Menu Bar Apps still work the same

  Apps still work the same when they are in Bartenders Bar allowing you
  quick access to them when needed, but keep them out of sight when not.

  Bartenders Bar can be placed where you want

  Bartenders Bar can be moved at any time to any horizontal position
  immediately under the Menu Bar. Or it can open under the Bartender
  Menu Bar Icon.

  Show an App in the Menu Bar for 5 seconds when it updates

  Set up your Apps to be displayed in the Menu Bar for 5 seconds when
  they update.

  Hide Menu from left of Menu Bar to display maximum Menu Bar Apps

  Bartender can remove the left hand side Menu temporarily to display
  the maximum possible Menu Bar Apps in the Menu Bar.


Accessing an MCU via minicom but it keeps saying Resource Busy

It seems like you have confused some things:
minicom is a program that will allow you to communicate with for example a different computer running Linux over a serial connection.
/dev/disk3 is a device node on your computer that refers to a physical block device (i.e. for example a hard drive or an SSD).
It does not make sense to ask minicom to communicate with an SSD disk. This is why your command fails.
Instead when using minicom you need to use the device node for a serial communications port. For example it could /dev/cu.usbserial or similar depending on the type of serial port you have.


Cannot initiate Windows 7 install on MacBook Air bootcamp

I got it sorted, it was probably my fault not understanding the options properly.
The actual install can only be started by that last option that says eider:

remove windows 7 or later version

OR

install windows 7 or later version

So if you already have a Windows partition created you will see remove windows 7 or later version, you need to remove it and then it will change into install windows 7 or later version, after creating the partition again, it will restart and the install will begin.

If you already have the bootable stick previously created by these steps, just plug it without checking first two boxes (create boot stick, download support software), creating that stick would take hours.

I think Apple could make it more clear (the re-install part).


How to stop my Mac from cloning MP3 files on my USB stick?

If you delete them manually a lot of them will reappear at eject. .DS_Store, trashes, fseventsd & spotlight files especially.

There have been a number of software solutions over the years, most only partially successful. BlueHarvest was about the best I'd tried until recently, but wasn't 100% effective.

I'm currently testing CleanMyDrive, freeware, though they are using it as a bit of an advert for CleanMyMac for your internal drives, but you can ignore that. So far it seems to be fairly effective, but still misses the trash files every so often.


I have a 2015 15" running the El Capitan Gold Master and it still mirrors the displays. I wish they'd sort this out, I'm wasting a Thunderbolt port by having to connect both displays independently.


Is there a way to add shortcuts to open a particular folder in Save Dialogs and Finder Windows?

By default, no.  What I've done is drag folders I access frequently to the Places section in the left side bar.  There is software to accomplish this though.  Default Folder X does this, and more.

If you're in a save dialogue you can press / to get a file path dialogue, or press ⌘+Shift+G to get a "Go to folder" dialogue.


How to enable Three Finger Drag from command line

It took a lot of trial and error, but I figured it out:

You don't need to restart your machine after you enter this command for the setting to apply. Logging out of your account and logging back in again is sufficient.


How to create a new partition for OS X, then remove the original one

With Apple's OS X tools you can't expand the start sector of a partition to lower sector numbers. You have to choose another method.

You may accomplish your objective if less then one half of the net capacity of your hard drive ((~disk size - size of Recovery HD - size of EFI)/2) or less then one half of the main volume is occupied. If you miss the threshold narrowly you may remove swap files, sleepimage and clean the temp folders to lose further GBs.

In this particular case you may add a second volume with the same size as your then narrowed previous main volume, which is equivalent to splitting the available space in two equal volumes (with the first volume still containing your old OS X installation).

After installing your new OS X to the new volume ("El Capitan") you may transfer your apps, settings and data to the new volume.

After migrating your stuff you have to delete the old CoreStorage Logical Volume Group (the superior Macintosh HD) with:

diskutil cs delete lvgUUID

with lvgUUID: UUID of the Logical Volume Group. To get the lvgUUID use:

diskutil cs list

Deleting the Logical Volume Group will automatically create one new classical JHFS+ volume with the name "Untitled" occupying all available space on the disk.

Now clone your new volume "El Capitan" to the empty volume "Untitled" with an appropriate tool (Disk Utility/Carbon Copy CLoner). The former "Untitled" will be renamed to "El Capitan". So rename the former "El Capitan" to "El Capitan_Old"

After successfully booting from "El Capitan", delete "El Capitan_Old" with Disk Utility and expand "El Capitan" to the full available size of your disk.

If more than one half of your (old) main volume is occupied you need an external disk to migrate or you have to delete some data.


I'm sure you can create users manually from command line in OS X, and while I have a large *nix background, I'm only familiar with approaching this from a GUI standpoint in OS X (though like I said, this absolutely doesn't mean it can't be done.)

Simply get on the console or enable remote administration for your OS X user and VNC to the Mac from your desktop.  Or install xRDP on the Mac, which is my personal preference for GUI access from Windows-to-Mac.

From there, just go to System Preferences, and create the user accounts from there.  You can tweak the remote administration access to allow these users or add them to a specific group and give that group SSH access from there.

This will achieve what you're looking to accomplish.  If the basic commands are the same as what you are familiar with, just enable Remote Administration, SSH to the Mac, and do your thing from the command line.


Yosemite keeps restarting or going into grey screen

These symptoms imply an issue with your GPU. There is actually an ongoing class-action lawsuit against Apple regarding the AMD GPUs in the 2011 Macs (primarily MacBook Pros). I have seen the issue before in person; my sister's MacBook Pro just encountered it. The symptoms were just as you described: boot chime, Apple logo, spinning loader, grey screen, nothing else. Apple had recently started using lead-free solder for internal components in order to adhere to EU environmental regulations, but the solder is more prone to stress and cracking from rapid heat fluctuation, which can cause the GPU to slowly separate from the logic board. If this is in fact the case, you have 3 options:

Allow Apple to repair it: This will run you $310 if your machine is not under warranty (unlikely, since your machine is 3-4 years old). Apple will replace your entire logic board, which includes the GPU. The only problem with this is that they will be swapping in a logic board with the exact same lead-free solder, which one can consider to be a manufacturing defect. The new board will still likely fail in the future...which is why this issue is big enough to elicit a lawsuit.
Reball: Some 3rd-party computer repair establishments can remove the GPU from the logic board, replace the lead-free solder with lead-based solder, and fix the GPU back onto the logic board. This process is known as "reballing." It is often cheaper than the Apple repair, and more reliable (as long as the repair place is reputable, of course). This would void your warranty, but if you've read this far, yours probably expired already anyway.
Reflow: If you're willing to get your hands dirty, you can use a heat gun to melt the solder back down into place. This is called "reflowing," and is the same process used to fix the "yellow light of death" issue on PS3 consoles.

You can read more about the lawsuit here: http://time.com/3545723/apple-macbook-lawsuit/

How to keep your MacBook Pro cool (unibody)

I tend to remain sceptical of anyone making claims without valid and reliable data. With that said, some practices you list are of critical importance; others, I'm not sold on one bit. Please don't take this a slight against you, but rather as a criticism of your general claims (and lack of scientific data therein). Moreover, if you enacted all those changes at once, you'll never know which one made a real difference, and which one did absolutely nothing. Proper scientific methodology calls for the manipulation of one variable against a control (unless you want to run the more complex ANOVA).

  Clean your MacBook Pro fans from within... it's simple, open the
  bottom closure and blow the hell out of these fans

Absolutely. This is by far the most effective way to ensure your system continues to operate nominally over the years. It is sadly also the most neglected. Dust sticks to the blades (and most of the internals) creating a "sticky" residue and not only prevents the fan's blades from spinning at their optimum, but seriously restricts air flow. Computers generally accumulate far more dust than people expect. Regular cleanings are essential!

  Download and install Fan Control and run your fans @ 2800-3000 RPM

This of courses comes at a sacrifice to noise (increasing it) and I'd like to see data on how much cooler the chips operate with such a small increase to RPM.

  Ditch all browsers to Safari, I tried them all Firefox up to version 5
  and 7 (Aurora), Chrome and Opera... nothing beats the CPU usage (less
  of it) than Safari. Also flash youtube videos run with less resources
  on Safari for some reason

Again, I'd like to see some data being this claim. These guys have conducted some very loose tests that support your assertion, and I'm inclined to agree that Safari, being so tightly integrated into OS X should net improvements over its competitors across the board, but a few CPU cycles here and there aren't going to amount to a drop (drastic or modest) in temperatures (these saw extremely small differences in performance).

  Use your faster GPU on AC Power, and lower on Battery power (use
  http://codykrieger.com/gfxCardStatus for source-based GPU switching)

GPUs put off heat, wether they're integrated or discrete. I can see a reduction in power, but a reduction in heat, again, I'm not sold. In the case of MBP, models that possess discrete video cards have dual fans (one for the CPU and one for the GPU). So using the discrete card may kick off additional heat, but it's also got a dedicated fan to push that heat away from the machine. Stressing the integrated chip will see the CPU spike in temperatures, which means that fan will be doing more work to handle the additional load. It may be the case that the fan on the CPU (together with the integrated GPU) may be sufficient in pulling away the excess heat, but at no doubt the cost of excessive noise (generated by 6,000 RPMs). I don't know if anyone has done testing, but from my own anecdotal experience with my old MBP1,1, the GPU fans rarely switched gears (unless playing intensive games and then the issue would be moot as you'd want to use the discrete video). It was always the CPUs fans that took the brunt of the work.

  Replace your internal hard drive with an SSD

Not only will this greatly improve performance, but it can't hurt in reducing temperatures. The idle/active power consumption of an SSD is about 0.5W to 2w, respectively. The average power consumption of a traditional HDD is about double that (1W to 2.5W, respectively). I won't know what that transfers to in the temperatures department, but it certainly can't hurt.

  Keep your monitor running @ 90% brightness and keep your keyboard lights off or low

I'd love to see data on this. LED backlighting is already quite efficient and distributing heat, but I'm not sure a reduction (at least that small) in power would have any effect. As for the keyboard lights, those are LEDs and as is with such small LED bulbs, they are incredibly power efficient and produce little to no heat as a result.

With all that said, I'd saying re-application of Arctic Silver 5 (or thermal compound of equal quality) and the cleaning of dust from the internals is the most effective (and proven) way to keep your system cool. I've never seen data to convince me that turning off some service, or placing your system on a pad with a couple of fans does anything (other than perhaps keep the case cooler to the touch) worth merit.


As a general rule: don't delete anything in ~/Library. Those are private folders used by apps to save configuration and data.
The ~/Library/Application Support/Mail folder in particular holds configuration files.
Don't delete ~/Library/Mail either, if your mail provider uses POP3 you'll lose all mail, if your mail provider uses IMAP the Mail app will have to download messages and attachments again.
To free up disk space delete mails you no longer need and then simply empty the trash:

iMac Boot Camp: No bootable device error when installing Windows 7

You can not use a USB flash drive to install Windows on a 2010 iMac. You need to use a DVD. You can install without a DVD or flash drive, but the procedure is difficult and requires installing third party software.

There are two methods to boot software on your Mac. The older (legacy) method uses the BIOS firmware and the newer method uses the EFI firmware. OS X and many Linux operating systems can be installed to boot using the EFI firmware. Many have attempted to install Windows to boot using the EFI, but doing so in my option is rather pointless. To get all of the device drivers to work properly, you need to install the proper "Boot Camp Support Software". This software assumes you have installed Windows to boot using the BIOS method.

It is my understanding the newer Macs do install Windows to boot using the EFI. All the 2010 models were not designed to do so. Also, the 2010 models were required to install Windows using a DVD. Apple changed the firmware to allow USB Windows installs around 2012, when they stopped putting DVD drives in Macs. To my knowledge no firmware upgrades were ever released to allow USB installs on 2011 or older Macs.

In the case, where you no longer have a working DVD drive, you can still install Windows directly from the ISO file. This requires installing a free copy of VirtualBox. This product can be used to prepare a partition for the installation of Windows. Once Windows is installed, you can remove VirtualBox, but since it requires very little disk space, you are better off just leaving a copy on your Mac.

Instructions to install Windows 7 without DVD (Optical) drive or USB flash drive

The procedure can be found at the link below.

Delay in keyboard responsiveness after wake with Mountain Lion?

While I believe Macbooks Air did this before Mountain Lion, you seem to be experiencing a resume from standby. All Mac laptops, by default, write the contents of memory to disk when they sleep, but leave the power to the RAM on for a quick resume. Writing the contents of memory to the disk occurs so that you won't lose data if the system loses power.

However, on Macbooks Air and Retina Macbooks Pro, which have built-in Flash memory (which Apple distinguishes from 2.5" SSDs on Macbooks Pro), in order to advertise a 30-day standby time, after an hour the system removes power from the RAM. So, if you leave it asleep for more than an hour, you'll actually be resuming from the disk. It's a lot faster than on a device without an SSD, but it's still a noticeable delay. Apple calls this "standby", and while it's resuming you basically see a still image of the login screen that you can't interact with.

You can disable standby with this unsupported command: sudo pmset -a standby 0. This will cause your battery to drain much more when you leave the system asleep, but it'll make it resume much more quickly.

Apple's documentation on standby mode is here.


OS X Terminal: "backward delete word" works only with C-M-h

Settings in DefaultKeyBinding.dict don't apply to the shell views in Terminal or iTerm 2.

You can make M-h delete a word backward by adding this to ~/.inputrc

"\eh": backward-kill-word

M-h is bound to mark-paragraph by default in Emacs though.

If others search for how to make ⌥⌫ delete a word backward, just enable using option as a meta key:

In Terminal, check Settings > (your profile) > Keyboard > Use option as meta key
In iTerm 2, set the option keys to act as "+ Esc" in Profiles > (your profile) > Keys

If others search for how to make ⌥⌦ delete a word forward, you can make it insert \ed:

In Terminal, there is no automatic detection for missing Rosetta to run older architecture command line tools.
If you haven't been prompted for any other app already, manually install Rosetta 2:
softwareupdate --install-rosetta

If you need to run a universal binary in the previous architecture, use arch and specify the architecture. You need to manually specify the architecture for binaries that need to run other binaries that are not built for Apple silicon, like Homebrew.
arch -x86_64 …

e.g. arch -x86_64 brew install packagename
Alternatively, you can run the entire Terminal app using Rosetta by opening Get Info on Terminal.app in Finder and checking ‘Open using Rosetta’. This way will Terminal and every binary it tries to run through Rosetta, so Apple silicon binaries won't be supported and performance will be impacted, but you don't need to specify the architecture to run old binaries.


Mail signature doesn't get added above quoted text

It is correct that you can not choose signature after you started the reply using the "None" for Signatures and if you only have one signature on file.

It will Automatically use NONE if that is your original setting in signatures.

Here is my work around that:

First the solution will allow you to normally start replies without Signature.

If you now decide to Sign, you will have the option to choose a Signature.

To do that you just make a empty Signature in the Mail Preferences Signatures, using the + to add and name it something other than none (I called it test)

Now you should have 2 signatures to choose from.

Your original and the new one containing nothing.

In Signatures window choose the new one as default.

Now in replay to email, you will have no signature by default, but you can switch to the actual signature and it will be on the top of the Quoted message.


Tata photon 3g dongle crashes after upgrading my OS to Yosemite

I found a way to make dongle work in the yosemite(Mac OS 10.10).

Go to the system preference and click on network.

In network it will show you the dongle option like in my case my dongle name is ZTEUSBModem.

And enter the phone number "*99#". Click on connect.

Your mac is ready to work with the dongle. There will be no need to run the tata docomo app.

Its working in 3g mode.

Its working good for my mac.


I use AppFresh. It's nearly perfect. A lot of apps are recognized, even new ones and widgets and prefpanes too.

It's backed up by iusethis to check for update, but can also check for Apple or Microsoft Office updates.


How to name a deskop in mission control?

You cannot rename desktops in Mission Control.
You can’t rearrange or rename Spaces, either.
You get Desktop 1, Desktop 2, and so on, and that’s it.
This Thread should give you more information.


macOS Sierra: Pulse Secure Client client broken

Install 5.2.5 and it should work again.  You can get it here: https://admin.kuleuven.be/icts/services/extranet/ps-pulse-mac-5-2r5-0-b869-installer.dmg

More info in Apple's discussion forum:  https://forums.developer.apple.com/thread/49006


For starters, OS X doesn't have the silly 64/32-bit dichotomy that Windows and Linux do. For most purposes, you can consider recent versions of OS X to be both 32- and 64-bit at the same time. The limiting factor in almost all cases of upgrading Mac RAM is the hardware chipset.

For your Mac mini 4,1: my copy of Mactracker says that the maximum RAM is 8GB. Your five-gig setup should work fine.


Emerald, amigo:

Let's get your Mac working for you:

Reboot the machine, holding down the appropriate keys on your
 windows keyboard to effectuate an Apple COMMAND-s.  Two keys here,
 the 's' for single-user, and whatever key maps to the COMMAND, or
 APPLE key.  If all goes well, then a nerd-screen, like a DOS prompt
 or UNIX shell will appear instead of the normal boot process.
Please execute the fsck as it is suggested above your command prompt.
Should be something like

      /sbin/fsck -fy

Let's mount the root partition in read write mode:

      /sbin/mount -uw /

Carefully delete the one file in the way of your enjoyment of your
new Mac -- no re-installation shenanigans required:

     rm -f /var/db/.AppleSetupDone

Proper restart:

     sync ; shutdown -r now

Next, create your new admin account, as if this was the first time you ever used your new Mac.

Enjoy,

Why does iphoto only open 4 images in the external editor?

I believe this is to protect against User error - the kind of thing that happens when an inexperienced user doesn't realise that s/he has every photo in their Library selected and then opts to send to the external editor.

No, there is no setting to adjust. Nor have I ever found a way to hack the limitation.


how to ignore all the node_modules folders from time machine

I'm one of the maintainers of Asimov, a free macOS utility for automatically excluding development dependencies (npm, Composer, RubyGems, and more). It was designed for this very purpose ::looks begrudgingly at node_modules/::
The easiest way to install Asimov is via Homebrew (brew install asimov), but the GitHub repo also has manual installation instructions. Once installed, a cron job runs every day to find development dependencies and automatically exclude them from Time Machine via tmutil (mentioned above).
One more benefit is that Asimov checks for the dependency declarations (in the case of node_modules/, a package.json file) before excluding the directory from backups.
Hope it helps!


Terminal/ZSH Problems & Permission problems

The error message- /Users/flawn/.zshrc:.:1: no such file or directory: /usr/local /etc/profile.d/z.sh comes from line 1 of your .zshrc file and suggests that there is a space between the command substitution and the rest of the path-

 . `brew --prefix` /etc/profile.d/z.sh
                  ^space

Back ticks for command substitution have been deprecated for a long time in favor of $(.....) but you would be better off using the absolute path to the sourced file-

. /usr/local/etc/profile.d/z.sh

or comment line 1 out if z is not installed.

#. `brew --prefix` /etc/profile.d/z.sh

In line 20 remove the curly quotes-

DISABLE_UPDATE_PROMPT=„true“

Last, terminate the last line of your .zshrc file with a newline.


No, you cannot do this. I understand it would help a lot in your case.
There might be a jailbreak-tweak, but since my iPhone isn't jailbroken I cannot give you the right repo or even tweakname.

Not sure if this will help some people, but I figured this out for myself

I have a 27" LG WQHD (2560x1440) display connected via HDMI to my 2014 13" Macbook Pro Retina.

Enable Mirror Displays

On the external monitor, select Optimize for: Built-in Retina Display

The final result isn't perfect, but it makes my 27" external display look like a beautiful retina display.

  Two downfalls:

the macbook has to be open in order for the external to continue running in HiDPI mode.
the external monitor has an aspect ratio of 16:9 but the laptop is 16:10. There are thin vertical black bars on the left/right of my external monitor.


How to delete email messages from Spotlight search on iPhone?

i have just hopefully cured my problem - delete all the stuff you want gone, go backup your device, then go to delete all data and settings on your fone and choose restore from back up - then your device should be as it was but without the old deleted data saved


Can I restore an iPhone backup taken from a previous iOS version, or is there a better way to retain my data?

Yes, this is possible.  The backups themselves contain application data and other information that isn't particularly version-specific (with the exception of going from 4.3 backwards, as pointed out by hobs above).

In fact, I had to do this exact process recently, going from 4.2.1 to an iOS 5.0 gold master on an iPhone using a backup, and it went off without a hitch.  Developers who want to install a prerelease OS version must put their devices in recovery mode, clean install the OS, then restore application data and settings from a backup.  I did this for my iPhone, which I hadn't upgraded to the latest 4.x OS, and everything came across cleanly to iOS 5.0.

The one thing to watch out for is that if you don't encrypt your backups (by selecting the "Encrypt iPhone backup" option in iTunes), your device's keychain will not be transferred to the new device. For non-encrypted backups, the keychain is only preserved when restoring onto the same device you backed up from.


What if you unsubscribe from the holiday calendar and then set the time zone on your phone to be exactly what you want.

Then power cycle it (to be sure all the apps know and can read the correct zone).

When you subscribe back to the calendar - pay attention if there are advanced options on time zone.

We might need to know the exact subscription URL you're using and which account backs this calendar. iOS calendars can be stores in Exchange, O365, google, iCloud or other third and first party solutions or not sync at all. Depending on your specific set up, the time zone settings might not even be on your phone if you're syncing down from a cloud service.


"The file name is not valid" error when trying to use "Get Group from Matched Text"

Another way I debugged this issue was I changed what it was matching. E.g. instead of matching the URL, I decided to match the "Click here" to see what would happen:

Accepts URLs
Get contents of [URL]
Make HTML from [Contents of URL]

The HTML at this stage is something like this:

Click here

Match (Click here) in [HTML from Rich Text]
Get [Group At Index] [1] in [Matches]
Show [Text] in Quick Look

Sure enough, this worked. Quick Look showed me:

  Click here

This made it clear that there is something going on with text that happens to be in the format of a URL in Quick Look.

The Get Type (along with Quick Look right after it) was helpful in debugging and figuring out what the issue was.

There were a few non-obvious things going on here:

When testing as a shortcut, the type of the text before reaching Quick look was Rich text. When testing with the Text action, the type of the text before reaching Quick look was Text.
If Quick Look receives Text (even if it looks like a URL), it'll display the URL as plain text.
If Quick Look receives text that looks like a URL of type Rich text, then it will try to display the contents of the URL, as though it's a local file (or something like that). This will most likely result in the The file name is not valid error mentioned above.

The fix, then, is to force the contents to be converted into plain text by adding an extra step right before the Quick Look:

Accepts URLs
Get contents of [URL]
Make HTML from [Contents of URL]

The HTML at this stage is something like this:

Click here

Match Click here in [HTML from Rich Text]
Get [Group At Index] [1] in [Matches]
Get text from [Text]
Show [Text] in Quick Look


How to Have CSS Content Preview in Finder?

This the icon generation is dependant on the associated app for that file type, so associating .css files to TextEdit might get them to be treated as plain text in the icons. It's worth a shot, I guess.

How do I disable iMessage for a contact who no longer has an iPhone

To dissable iMessage on your phone (the one who has changed from iPhone to something else):
http://support.apple.com/kb/ts5185

Since it’s not your phone that needs changing, Your friend is the one that needs to take action to Approve the request to de-register their iCloud/AppleID from their phone number - https://selfsolve.apple.com/deregister-imessage

As long as their SMS number is associated with iMessage via their Apple ID, iMessage delivery will be preferred by iOS when sending. If you must send an SMS without them fixing their account, you can turn off iMessage entirely on your iPhone and then send a SMS via your cellular carrier to that contact before turning on iMessage again if you wish to have that for other conversations.


The best you can do in Pixelmator 1 is arcs using the oval selection tool. Select an area with the selection tool set to the circle/oval setting and then trace the selection (Edit -> Stroke) on a new layer. Once traced, erase the part of the trace you don't need. Reposition, stretch and mangle with the layer tools.

Pixelmator 2 adds vector drawing capabilities. It'll be available this summer and it will be a free upgrade for anyone who purchased Pixelmator 1 via the App Store.

Update: Pixelmator 2 was released via the App Store today and the pen tool lets you draw and manipulate curves now. Works great.


What does the checkbox for some apps in iCloud > Options > Documents mean?

Firstly, the checkbox for Mail just means it syncs Mail.app settings via iCloud and also it enables the iCloud Account in Mail.app or turn it off.

Secondly, System Preferences settings are also synced via iCloud, for example iCloud syncs my preferred Wifi to any new iOS or Mac I enable iCloud on.

Likewise Weather locations for any city you setup is synced over iCloud.


Select the text and right click to select "Format Text…" from the contextual menu.

Click "Text Fill" to find the "Gradient" settings.
Click "Text Line" to set outline colors.
Click "Text Shadow" to set shadow settings for the selected text.


How to capture audio with Quicktime Screen Recording

You could use Audio Hijack (per Tetsujin) to capture the audio as needed or you could use a USB audio adapter to do it for significantly less.

I use the Behringer UCA202 Audio Interface with my iMac.

When I needed to record a screencast with the audio from the application, I just used an RCA audio cable I had laying in a drawer similar to the image below.  You don't need anything fancy or expensive, just a standard RCA audio cable.

In quicktime, I just selected the USB device as my input:

Now, when I say significantly less, Audio Hijack is about $50 if buying the new license.  The USB Audio device is $30 and if you have to buy an RCA audio cable, you're looking at another $5.  So, for $35,  you get an audio interface that has many more uses than the software can provide (for example, I can hook my Bose Wave Radio to my iMac now) whereas the software doesn't allow you to do that.

Make no mistake, Audio Hijack is good software.  This is just another, albeit less expensive, avenue to solve your problem.


How can I know which GUID represents which app in my iTunes backup of my iPhone?

This used to be possible with Erica Sadun's mdhelper program.  Unfortunately, it looks like something has changed in the way Apple stores backup files w/ iOS 4.2, and the program cannot achieve the same results (since it finds no mdbackup or mdinfo files).

On the bright side, a new tool named iPhone / iPod Touch Backup Extractor has emerged.  It correctly translates the GUIDs to names in my iOS 4.2 backups, and allows the files for each app to be extracted together.


Apply Options > "Assign to" - "All Desktop" only to 1 chrome tab?

This is not possible natively. The desktop assignments are on a per-app basis, and not customizable by window.

A workaround could be to use Fluid, whereby you could create an actual application for the web app. This application could be assigned to all spaces.


Should i Buy SSD first or RAM for my Macbook?

Don't get a 128GB SSD. You don't want to run a 3rd party SSD on OS X without a decent amount of free space since you won't have TRIM support.

Does Activity Monitor show memory pressure? If not, I'd save my pennies until I could afford a 256GB or 512GB SSD. I've done both RAM and SSD upgrades many times and an SSD has always been by far the best upgrade in changing the "feel" of the computer.


How do I make Messages.app override a contact's buddy icon?

Is there any way to stream my Mac Pro to my MacBook?

I regularly use VNC and ssh to my Mac Pro from my MacBook all the time to do things my mobile CPU doesn’t thrive on. This is very efficient for me, so I’m not sure what is lacking in your setup. Run server apps and calculation and Xcode builds on your MacPro and let your MacBook do the things it is suited.

screens app is great for remote screen viewing
prompt app is great for ssh from iOS

I have App Store caching service on the MacPro and iCloud caching and run longer compiles remotely and anything I can script and batch as well.

When that’s not enough, run things in Azure, AWS, google compute or a Mac hosted service, no?

Is there any service to rent cloud CPU power to increase my mac power?

Format disk with one Windows and one Mac partition

If you have 2 hard drives you can do this way:
1) On 1st drive install osx. Then use bootcamp assistant to re-partition the disk 1 and install windows on second partition. At this point you can via disk utility format the second drive as you wish (e.g.: second drive 1Tb= 500gb fat/ntfs for win data and 500gb hfs+ for osx data);
2) On 1st drive install osx. Then use bootcamp assistant and select secondary hd (not the osx' one) and install windows. Now you have dual boot on 2 separate disk, 1 fully dedicated to osx and one to windows.


How can I check the hardware of a Mac Pro 1,1 running 10.6.8?

Download the AHT for your computer model and use the contents to restore the /System/Library/CoreServices/.diagnostics folder, then reboot while holding D to start the diagnostic tools.

There's no need to burn something to disc.


Finally, after many turns, I've found what's going on:

The executing shell/app in the script (e.g. zsh, sh, python - in my case /bin/bash) needs to have Full Disk Access privileges. In order to do so I went to Apple Menu > System Preferences > Security & Privacy, selected Privacy tab, unlocked the settings and added /bin/bash to the list.

Now I can read and write the mounted share.


Is it possible to schedule send an email using the default Mail OS app?

Mail doesn't have this feature out of the box but you can use your native Mac apps to schedule an email. My answer is based on macOS Catalina but it should be practically the same besides some minor differences, placement etc.
Using Automator and Calendar:

Create an email workflow using Automator; then
Add the Automator workflow to a new Calendar event (formerly iCal)

1. Create an email workflow using Automator
First open Automator app, which is found in the Utilities folder, and choose New Document. When you see the workflow type chooser, select Application.
Select Mail from the Library pane on the left, and a list of Mail actions will show in the Actions pane to the right. Scroll down and you will see the New Mail Message action. Double-click it or drag it to your workflow.
Once you've composed your message, add the Send Outgoing Mail action to the workflow. Now save the workflow and quit. Make sure the format is set as Application.

2. Add the Automator workflow to a new Calendar event
Open Calendar app (formerly iCal) and choose New from the menubar, or select an existing event to edit.
Give the event a name and set the time and date as per usual. Where we can set an alert, we'll select Custom. From the dropdown, choose Open file, and from the next dropdown, (currently labeled Calendar) select Other. Now browse to the Automator workflow app from the previous step. Save the event and quit.
Should be good to go. Don't forget to keep your Mac turned on.
Edit: Using Calendar without a Automator workflow
The Calendar app lets you send an email as part of an events alert. Similar to the first method, instead of selecting Open file after choosing Custom for the alert type, you can select Email.
Not sure how long this has been an option or if its available in earlier versions of Calendar and iCal.


Safari web browser do not find strings on a page in the common way

The find banner was set to match the starts of words by default in Safari 5.1:

This makes it default to Contains:

You have to quit and reopen Safari to apply the changes.


Does lost mode goes into effect once iPhone is turned on

If the phone ever gets an internet connection again it will go into effect, yes.

However if your phone was stolen, you risk that the thief will wipe it and sell it off - probably as parts - and your lost mode setting will be for nothing.

As you have no pass code on the phone, they will be able to see all your pictures and data, yes.


Can I install Linux and Windows on a Mac to triple boot the hardware?

It's possible to install them in multiple partitions and multiboot. But the resulting setup will be a little "rigid".

Doing OS X and Windows is easy. Adding Linux to the mix is a little more complicated.

I suggest you do not multiboot and only install OS X as the main OS and then use a virtualization solution, like Parallels Desktop or VMware Fusion. With those you can basically run a whole operating system, like Windows or your favorite Linux distribution, as if they were OS X applications.


Using "tmutil set destination -p" fails with a failure to save the password to the keychain

It seems that this was due to having a user password on the server (the "destination" password) that had special characters.

This was the original password:

cDWo3fVq%2XKg}T/r,2C)jV.bZcB3FxRU*sJ2UW2&s+2[2X23b

Changing the password to a string of letters and numbers without symbols saw the username/password pair save successfully to the keychain.

iOS 5 was released in 2011. A new major iOS version is released every year.

iOS 5.1.1 is the last supported iOS release for iPad 1. A lot of apps on the App Store no longer support iOS 5 as it is outdated. Basically the recent version(s) of iOS have advanced way past the features and technologies (due to new hardware features and advancements) available around iOS 5.

You’ll be able to find very few apps on the App Store capable of running on iOS 5. With Apple's push for keeping the apps up-to-date and dropping support for older software releases, a lot of the popular and commonly used apps are no longer iOS 5 compatible.

iPad 1 can not be upgraded past iOS 5.1.1 which is the last supported release for the device.


What is the AppArt process and why does it want to connect to application-stats.com?

Following @tubedogg's comment above, I think I've fixed this:

http://www.malwareurl.com/listing.php?domain=application-stats.com identifies the domain as Malware
Double-clicking the "AppStats" process in Activity Monitor and then clicking the "Open Files and Ports" tab reveals that something is running from /Users/jim/Library/Application Support/Spigot/AppStats
Searching "Spigot" then takes us here, which gives removal instructions: http://www.thesafemac.com/arg-spigot/
I didn't find any weird browser extensions in Firefox, Safari, or Chrome (the directory in Application Support included a file with a name that referenced a .xpi file, so I'm guessing the problem may have been something to do with an old Firefox extension) but I did remove the following directories and files: ~/Library/LaunchAgents/com.applicationstats.AppStats.plist, ~/Library/LaunchAgents/com.appart.AppArt.plist, ~/Library/Application Support/Spigot/
