Chosen Solution
I bought a Mac Pro (late 2013) [macpro6,1] from a friend and installed a new flash SSD. To help cut to the chase with formatting, I used a bootable USB to load Mac OSX Mojave and can confirm through terminal info that the new ssd, named “NewSSD” has an APPL_HFS partition type, Journaled HFS+, OS can be installed, and the device is internal. I can select NewSSD as the startup disk and have tried to boot to it, but can’t for the life of me get it to function and start the operating system. I have tried reinstalling a few times and the same thing occurs. HOWEVER, I tried using 2 other bootable USB drives and then the internal disk does not appear in disk utility in recovery, so for some reason it seems to only be recognizing the disk when I have my original boot drive plugged into the USB. So to recap, I can see the NewSSD in disk utility in recovery, I’ve run first aid on the drive no problem, but then it doesn’t boot the operating system. Any thoughts? @danj ?
Sorry, the Mac Pro’s require a real Apple blade SSD* for their boot drive. While I know some people have managed to use these adapters and a M.2 drive in the MacBook Pro’s I have yet to see it work in a Mac Pro. Frankly, I have seen more problems using this setup. Last month alone I had to replace two back to real Apple SSD’s. To salvage things I used an external M.2 case. For my own Mac Pro I wanted to push the storage I went with a RAID case using M.2 SSD’s OWC Express 4M2. OWC also offers a workable SSD as well! Thats what I have in mine. OWC Aura SSD for Mac Pro Take the time to read this: The Ultimate Guide to Apple’s Proprietary SSDs it should help explain things. BeetsTech is also a great source for the needed SSD. Hopefully you can get your money back
