been fighting my mac for weeks now, with constant freezes, hangs, system-wide crashes or video corruption from 1-100 minutes after reboot. seems i followed some bad advice in the past and turned on something i shouldn’t have. so, my thing for today is sharply worded advice:
Do not enable QuartzGL (2D acceleration) on your Mac Pro. To check that QuartzGL is off, open Terminal, paste in this line and press Return:
sudo defaults write /Library/Preferences/com.apple.windowserver QuartzGLEnabled -boolean NO
Reboot to make this take effect. Voila, no more annoying crashes. You’re welcome.
