Performance Tweaks/Tools for MacOS (Macbook Pro)
Onyx is a great app to help you clear out a lot of the clutter you may have accumulated over the years and speed you up a bit. Be careful though, it's a powerful tool so make sure you know what you're doing with it before you do anything.

As for boot time, make sure you don't have a lot of daemons loading at launch. One easy way to check is to go to System Preferences > Users &amp; Groups > [Your User] > Login Items and remove anything listed there that you don't need launching at startup. Anything with a default document icon means it doesn't exist and can be safely removed. Ideally, the only item that should be listed is iTunesHelper, but if you don't use any iOS devices, then you can remove that too.

Another few places to check for daemons and login items is "~/Library/LaunchDaemons/", "~/Library/LaunchAgents", "/Library/LaunchDaemons" and "/Library/LaunchAgents". If you see anything listed for software you don't use anymore, trash it. Certain other apps load daemons in to here too that you might not need; Adobe is a big culprit here with their Flash Player updater, Adobe Reader updater, and AAM. If you're unsure, leave it where it is.
