#1 – if your MacBook Pro 2011 model currently has SATA 2.0 3Gb/s reported for your optical bay max link speed, this EFI update does not change that to SATA 3.0 6Gb/s.
Very important points though concerning the optical bay. We are very thankful and excited to see the ‘quiet’ fix for 6Gb/s SATA 3.0 main bay drive reliability as a further benefit of this update. Nearly seven months after these machines first became available, all indications are that we can now reliably count on taking full advantage of the 6Gb/s capability provided.Īpple has somewhat dodged giving any direct response on the issue itself, but this long awaited solution just happens to be there in this update with the official description on Apple’s support site only mentioning the update as addressing Lion Internet Recovery and Thunderbolt. Well, if you ran Software Update this morning, MacBook Pro EFI Firmware Update 2.2 appears to be the answer. If you’re not familiar with it, the short form is that in many 17″ 2011 MacBook Pros (and some 15″ and 13″ as well) had problems with SATA 3.0 Revision SSDs such as the Mercury EXTREME Pro 6G- through no fault of the SSD- resulting in spotty performance, beach ball timeout delays, and even complete failure to recognize SATA 3.0 6Gb/s SSDs at all. If you’ve been reading the OWC Blog for the past few months, you’re probably well aware of the problems that 2011 MacBook Pros were having with 6.0Gb/s SATA performance.
