[MacOS] Enable Quartz Extreme 2D



  • open terminal
  • enter: sudo defaults write /Library/Preferences/com.apple.windowserver Quartz2DExtremeEnabled 1
  • By the way: you may find this command on the net aswell: sudo defaults write /Library/Preferences/com.apple.windowserver Quartz2DExtremeEnabled -boolean YES – it does perfectly the same like the first command and is only a matter of taste!
  • then reboot and be happy.

There is also another way via using QuartzDebug (search for it on the net, it required the Development tools on the Leopard disk)…

    I have installed OSX on a virtual machine (virtualbox) but quartz extreme is not being recognized! I however believe my graphic card is able to support it. It is a nvidia geforce GT 540M. I had a look on the nvidia site but have not found any info on whether my graphic card supports it… Could somebody give me a link to help find out?
    I therefore think the problem comes from the virtual box! Is there a way (wathever solution) to make it work on a virtual box? It seems impossible to make iMovie work without quartz extreme… :-(
    Otherwise, is there an app that woul simulate or force its recognition or its processing?
    Thanks in advance

    I’m also trying to get iMovie’11 to work within virtualbox under Mac Os Lion. Any help would be truly appreciated!

    I belive that virtualbox dosent support quartz extreme, because i cannot get it to work… and i know that vbox uses its own emulated graphics card, so it shouldnt matter if it supports it or not
