I just installed a 500 GB Samsung 850EVO SSD in a 2008 Macbook4,1. I had to reformat the SSD for Mac, so I put it in an Inateck enclosure for a 2.5” hard drives — worked great. Gave the MacBook a whole new lease on life, and if it dies, I will put the SSD in another used computer. :-)
Great job — thank you!
