The EFI Firmware Update released yesterday solves problems with SATA 3.0 SSDs, reports OWC.
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.
Well, if you ran Software Update this morning,EFI Firmware Update 2.2 appears to be the answer. 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.
