Apple’s in one of its update-o-rama sprees again and late Wednesday, the company released firmware updates for its popular 27″ iMac line.
The first update, the 27″ iMac SMC Firmware Update 1.0, a 397 kilobyte download, fixes Target Display Mode compatibility issues on 27″ iMac computers.
The second update, the 27″ EFI FW Update 1.0, a 2.0 megabyte download, addresses the newer Intel Core i5 and i7 iMacs and fixes the following issues:
– Resolves an issue that sometimes caused high processor utilization while playing audio through the headphone output mini-jack.
– Resolves an issue that prevented the display backlight from turning on after powering on the iMac.
Both updates can be located, downloaded and installed via Mac OS X’s Software Update feature and require Mac OS X 10.5 or later to install and run.
If you’ve tried the updates and noticed any differences, please let us know.
