Hi![br]
So I have this Macbook Pro Early 2011 13" A1278. I want to upgrade it to an SSD.
I cloned the HDD to the SSD, all seemed good, but would get the prohibitive (circle crossed out) logo when trying to boot.[br]
Attempts to clean install onto the SSD have failed.[br]
I have read up on this and it seems these Macs won't run SATA 3 SSDs with SATA 2 cables, which is very strange. I have installed many SSDs into Windows PCs with SATA 2 controllers and never had any issues.[br]
So either the cable is faulty, incompatible, or both. People have recommended to get the 2012 cable which is wider. But I want to double check that it would fit or if any modifications are needed? And how do I know which cables are actually SATA 3 or SATA 2? The sellers never clarify that in their listings.[br]
Also curious... if you were to install an SSD (SATA 3) into one of the 2009 models that don't support SATA 3, what would happen? A windows machine would work perfectly fine, but from what I've read the Macs won't.
PS... I have tested the SSD in another PC, works just fine.
Thanks you!
