I am trying to install Android Studio on Mac OSx, with the goal of learning some Android development. The instructions provided were simply to:

```
1. Launch the .dmg file you downloaded.
2. Drag and drop Android Studio into the Applications folder.
3. Open Android Studio and follow the setup wizard to install any necessary SDK tools.

```

I get to the setup wizard, select everything, give it 6 gigs of ram when asked, then it proceeds to download components and install. However, at some point a popup appears:

`The following SDK component was not installed: platform-tools`

The output shows:

```
Ignoring unknown package filter 'platform-tools'
Installing Archives:

    Updated ADB to support the USB devices declared in the SDK add-ons.
  Stopping ADB server failed (code -1).
  Unable to run 'adb': Cannot run program "/Users/me/Library/Android/sdk/platform-tools/adb": error=2, No such file or directory.
  Starting ADB server failed (code -1).
  Done. 2 packages installed.
Ignoring unknown package filter 'platform-tools'

```

If I proceed to click "Finish" button, it opens up the Android Studio. But under ***Preferences -> Appearance & Behavior -> System Settings -> Android SDK***, I see an error:

`Please specify a Android SDK Location`

There is [Standalone SDK Tools](https://developer.android.com/sdk/installing/index.html?pkg=tools), but I was under the impression that Android Studio would come with all packages needed to develop in Android:

`Note: If you have not yet downloaded the SDK tools, download them now. For a complete IDE and Android SDK package, we recommend downloading Android Studio.`

So I'm kinda lost on what things I should be installing. How can I get my Android Studio to 'work' on my Mac?
