Since storage upgrades are quite expensive for MacBooks, there are third-party adapters that allow using m.2 SSDs on Apple’s proprietary connector. Here I describe two of these connectors of Sintech.

Summary: the short Sintech adapter is 1.1mm thinner, which also fits in a 13" MacBookPro12,1, the long version does not fit. For a MacBookPro11,2, both the short and long adapter fit. I don’t see a reason to buy the long (or rather: thick) version.

Introduction & limitations

This guide is based on the following sources:

• Macrumors forum thread: specifically start post and Cmd+q’s guide
• The Ultimate Guide to Apple’s Proprietary SSDs by Cody Henderson
• Guide by Graham Stevens
• Similar tweakblogs post by DedSec85 Limitations:
• for <2015 MacBooks hibernate does not work anymore and should be disabled (unless you want to flash the ROM). Normal sleep works fine and on my MBP 2013 this was not a problem.
• Power usage/battery life might increase, depending on what SSD you buy, see ‘Comparison of tested NVME SSD models’ on the Macrumors forum
