How do you turn off version control in android studio?

Question

To disable VCS in Android Studio on a Mac do the following:

Android Studio > Preferences...

In the Preferences window, select Version Control and under Directory choose VCS dropdown to be <none>

Don't forget to click "Apply" in the general Preferences buttons at the bottom.

For 2021...

It would seem that Android Studio nowadays does not automatically start with version control turned on for a new project.

The default seems to be "off" at the beginning of a new project.

(It does conveniently make a ".gitignore" file for you but it does not default to trying to use version control.)

However, if later you do manually yourself start using git in the folder in question, Studio does turn on vcs inside Studio, i.e. exactly as seen in the image above. In that case you'll have turn it off inside Studio, exactly as shown above.

In Android Studio 1.2.x

FILE -> SETTINGS -> VERSION CONTROL

Here the root is shown, Press (-) button to delete.

The other answers weren't working for me, so I am adding my solution.

This message was driving me crazy:

I had trouble with the other suggestions, as my settings was not allowing me to save changes for version control none.

So I went into Version Control / Ignored Files and removed all ignored files for that project.

Then when I clicked back on Version Control

I found this in this answer here.

VCS is a project specific setting which you can modify by going to File -> Settings then checking under the Version Control heading.

Alternatively, you could disable a specific VCS plugin under the Plugins heading.

Note: I have not used GitHub as VCS, but you should still be getting error display (syntax checking) in the IDE. VCS usage should not disable that, since that would make the use of an IDE completely pointless.
