On Thursday, Apple released its 24-Inch LED Cinema Display Firmware Update 1.0, a 962 kilobyte download which addresses an issue that may cause intermittent display flickering. This firmware will only install on the Apple 24-inch LED Cinema Display when it is connected to a Thunderbolt-enabled Mac.
Apple has also noted that this firmware update may not resolve the flickering issue if a Mini DisplayPort extender cable is used and that some USB and FireWire devices may prevent firmware updates from installing correctly; disconnect non-essential devices and use only an Apple keyboard and mouse to apply the update.
The update is available via Mac OS X’s built-in Software Update feature and requires an Intel-based Mac and Mac OS X 10.6.8 or later to install and run.
If you’ve tried the update and noticed any differences, please let us know what you think in the comments.
