Late Monday, Apple released two firmware updates, one for certain models of its popular iMac desktop and the other for Mac Mini computers that address problems with noises from optical disk drives during startup and compatibility with memory upgrades.
Per MacFixIt, the Apple Mac Mini EFI Firmware Update 1.2 patch “improves compatibility with the latest Apple memory kits on Mac mini computers.” Oddly though, there is no specific memory upgrade for the Mac Mini on Apple’s memory selector over at http://store.apple.com/us/browse/home/shop_mac/mac_accessories/memory.
The Apple SuperDrive 3.0 firmware update will eliminate noise made by optical drives during system startup and when systems wake from sleep. This update will only work with the following firmware updates and Mac system models:
– iMac EFI Firmware Update 1.4
– Mac mini EFI Firmware Update 1.2
– iMac (20-inch, Mid 2009), iMac (24-inch, Early 2009), Mac mini (Early 2009)
As with any firmware update, you should only install it if you are experiencing the problems they address. If you do install it, be sure to not interrupt the installer. If the system lags do not press the power button to shut down, since an interrupted firmware update can irreparably damage your system.
The updates are available through Mac OS X’s Software Update feature and require Mac OS X 10.5 or later to install and run.
