Limited graphics performance in OS X recovery or safe mode

Your computer might have reduced graphics performance when you start it in OS X recovery mode or safe mode.

Some examples are:

  • Vertical screen "tearing" during window transitions or window dragging.
  • Sections of the screen that flash or appear to flicker, such as scroll bars or the Safari progress bar.
  • Overall slower video performance.
  • General graphics distortion or video anomalies.

Exit OS X recovery mode or safe mode and start OS X fully.

If you continue to have graphics issues, be sure you have the right OS X version (build) for your computer.
