Apple Quietly Issues a Fix for Flickering Cinema Displays on Thunderbolt Macs
If you’ve got a new Thunderbolt-capable Mac and you’ve got it hooked up a 24-inch Cinema Display, you’ve probably encountered a bit of flickering every now and again. I know I have, and so have a number of users on Apple’s discussion forums.
Thankfully, Apple has issued to firmware update to resolve the issue, but it won’t be coming via Software Update.
