(re)Enable Quartz 2D in 10.4.3
Authored by: SmokyMcPott on Nov 01, '05 06:55:15PM
As others have pointed out, the hints found elsewhere on this site which deal with permanently enabling Quartz 2D (Q2D) under 10.4.3 no longer works. Apple has apparently disabled this feature permanently until they get it production ready.

On a hunch though, I combined a couple of things, and apparently have permanently enabled it again (It's survived multiple reboots, at least). Here's what I did:

Using the Propert List Editor, I enabled Q2D by editing the 'com.apple.windowserver.plist' file, as outlined in this hint.

However, after rebooting, I discovered that the Quartz Debug app was still showing my Q2D as being off, and offered its usual "Enable/Disable" options, under the Tools menu.

Because I had done this before (it might be in the aforementioned hint), I knew that one way to enable Q2d under Tiger was to load the Quartz Debug app, enable Q2D from the Tools menu, and then force quit Quartz Debug (because if you exit Quartz Debug nicely, it resets Q2D back to its default "disabled" status). The downside of this technique is that Q2D immediately reverts to disabled after a reboot.

So... After enabling Q2D via the program, I force exited the app, and Q2D has been enabled since, with no signs of trouble yet (fingers are crossed). My guess is that one of several things has happened here:

  • Apple has modified Quartz Debug to not disable Q2D on exit with this latest update (not likely). Or...
  • By first enabling the Q2D ability via the PList editor, and then switching on Q2D manually in the Debug program, and then force exiting it may, for some reason, be telling the OS to keep this enabled when it boots.
Obviously, YMMV, but for me so far it's working, so I thought I'd pass along the details in case anyone else is trying to figure out how to do this.
