Doesn’t work at all. The Mac guy transferred my old one to this one. Not one feature works properly. I am also out 85.00 for the transfer. Stay away from this seller! Then I took it back to the Mac shop, and they said the screen had never been removed. The drive was bad. It most likely have been dropped at some point, which could’ve happened during shipping. They’re unsure it was refurbished. The upside is that the seller is trying very hard to make it right.
