MacBook Pro (Early 2015) hard drive upgrade
What type of SSD will work in an early 2015 MacBook Pro 13 inch screen? I was told by someone that Apple no longer uses SATA drives and that they now have their own proprietary hard drives and hard drive connectors. Can someone clarify this for me? I'd like to upgrade a 256GB drive to 500GB.
MacBook Pro with Retina display, Mac OS X (10.7.5)
