A friend gave me an SSD SAMSUNG EVO 860 , formatted with os x (higher than mine,maybe sierra ) and a lot of files.
I have mb pro 2009 os x 10.11 and the disk can’t detected . I see it at Disk Utility with usb cable , as a second disk with disk tray but nowhere else and without access. I don’t want to format it because i ‘ll loose the files . So, I need your help to get the files.
