(disables BeamSync automatically at every login)
Here is a simple Automator application I put together to automatically disable BeamSync when logging into Snow Leopard. It’s not a particularly elegant solution, but gets the job done; I have been searching online for that one program which supposedly existed some time ago on the link http://glyf.org/beamsync/beamsync.gz, with no success. The other option – to modify com.apple.windowserver.plist with Property List Editor and put value of “deferredUpdates” to 0, just didn’t work for me, not even when doing a terminal command “sudo defaults write /Library/Preferences/com.apple.windowserver Compositor -integer deferredUpdates 0″ and rebooting – the changes just won’t stick.
Finally somebody created a REAL app for disabling Beamsync, without needing to use Quartz Debug. It is called BeamSyncDropper
and you can get it here
. It also works with Snow Leopard.
Here’s a newer automator app that works with Quartz Debug 4.0 and Snow Leopard and later OSX versions. You can download QD 4.2 from here
. Download the zip with automator app from here
. Put the Quartz Debug app in the Application folder, then launch the automator app from anywhere. What the automator app does: it launches Quartz Debug, enables QuartzGL and disables BeamSync and hides Quartz Debug app. Changes won’t stick if we force-quit the app, so it must remain open – and hidden. That’s it, you can set the automator app to execute automatically at system launch.
