If you get the NWC jumper, your SSD should function properly. After getting the jumper, I was continuing to get a fault code (which ended up being a normal occurrence since the jumper is not from Apple,) but all the same, the SSD was a great addition to my old 21.5" mid 2011 iMac... which is what I'm using for this note.. pc

Toshiba Slim II (1TB External) is having issues & I’m attempting to replace it with an EVO 860 without any success. Seems Samsung Magician is not comparable with Mac OS (or, so I’ve now recently read.) Is this issue correct or am I missing something? I thought all the new EVO SSDs would work without problems an a Mac. My Mid 2011 iMac (21.5”) works great with an old Samsung SSD. What am I missing…?
