Will this be compatible with a MacBook Pro 2011?
Yes, this slimline SSD is compatible with the Macbook 2011. If this is your first hard drive upgrade, search You tube for "Macbook Pro SSD Upgrade (2011/2012/2013)" . He uses a 1TB usb to backup original drive. I'm not mac savvy, there must be other backup methods, just be certain that you can backup & restore.
