Application freezes (e.g., spinning rainbow ball) without a MIDI keyboard connected. (Mac)
Last Updated 5 months ago

Applies to OS X 10.4, 10.5, 10.6, 10.7, 10.8, 10.9, and 10.10

This is usually a sign that your QuickTime installation has become corrupted. eMedia titles make extensive use of Apple’s QuickTime technology to playback audio, MIDI, and video content. The spinning rainbow means we are trying to do something, but the system is unable. The easiest method for correcting this issue, is to:

  1. With your computer connected to the internet, launch “Software Update” from the Apple menu. Your computer will search the Apple server for any updates to your operating system.
  2. Install the updates. This will ensure that your QuickTime application is up to date as much as possible.

If QuickTime believes it is already up to date, navigate to the Apple website and download the latest version of QuickTime and run its installation. This will repair the current installation on your system.
