Reset Audio Balance

ResetAudioBalance.scpt

AppleScript which resets the audio balance to the middle on MacBook Pro (or any recent Mac, really) because:
MacOS X has this ancient unfixed bug with audio where your headphones' or speakers' balance becomes offset for no reason at all.

  1. Download the script and open it or copy and paste the code into Script Editor on OS X (tested on High Sierra).

  2. Go to File → Export... (see below)

    • Export As: "Reset Audio Balance"
    • Where: "Applications"
    • File Format: "Application"

    and Save.

  3. Go to Applications and double-click on "Reset Audio Balance". You may have to go into:
    System Preferences_ → Security & Privacy → Privacy → Accessibility (see below)
    and click on the lock icon to authenticate and allow "Reset Audio Balance".
    If it doesn't appear there, click on the "＋" button and choose "Reset Audio Balance" from Applications.

  4. To get it to run automatically at startup, go to:
    System Preferences → Users & Groups → Yourself → Login Items (see below)
    and click on the "＋" button and choose "Reset Audio Balance" from Applications.
    You may have to choose the Password tab and Login Items again for it to appear.
