Apple released an EFI update for the 2011 MacBook Pros yesterday that reportedly resolves performance and compatibility issues with SATA 3.0 SSDs, some of which Anand noted in our original review. Other World Computing singles out its own Mercury EXTREME Pro 6G drive in its testing, and records much-improved consistency and performance compared to the previous EFI version.

The update can be downloaded via Software Update or Apple's support page. It requires OS X Lion to be installed, and in addition to the SATA fixes it improves compatibility with Apple's Thunderbolt Display, improves Thunderbolt Target Disk Mode performance, and enables Lion Internet Recovery, an install disc-less OS restore feature introduced in Lion which was previously available only on the Sandy Bridge Mac Minis and MacBook Airs.
