Chosen Solution
I’ve tried 2 different hard drives in my MacBook after I had problems with the original. When I boot to the USB, disk utility doesn’t see the new hard drive. If I put the old one back in, it will recognize it, but it fails out when I try to format it. I’m hesitant to blame the hard drives since I’ve now tried 2, but I can’t think of another potential cause. TIA
I found the answer thanks to OWC’s very helpful tech support. The drive needed to be formatted for Disk Utility to see it, so I did that through the terminal and it worked great. It didn’t make sense to me that Disk Utility wouldn’t see the drive, and that //diskutil list disks// would, but there it is.
OK, I think I figured out the problem here! 2013 was a transitional year. For reference here’s the three models produced that year: MacBook Pro 15" 2.8 GHz i7 (Early 2013)MacBook Pro 15" 2.0 GHz i7 (Late 2013) Intergraded GraphicsMacBook Pro 15" 2.6 GHz i7 (Late 2013) Dedicated Graphics If you open each of these links and jump down to the ‘Storage Dimensions:’ line you’ll see the early model offers a custom 6 Gb/s mSATA interface, whereas the other two offer a custom PCIe 2.0 x2 interface. I’m suspecting you really have one of the late 2013 models which is why the SSD you got won’t work.
