Apple released its MacBook Pro EFI Firmware Update 1.7 patch on Tuesday, a 3.4 megabyte download which addresses an issue reported by a small number of customers using drives based on the SATA 3Gbps specification with the June 2009 MacBook Pro. While this update allows drives to use transfer rates greater than 1.5Gbps, Apple has not qualified or offered these drives for Mac notebooks and their use is unsupported.
The update is also available via Mac OS X’s Software Update feature and requires Mac OS X 10.5.7 or later to install and run.
