Use this guide to upgrade or replace the solid-state drive in a MacBook Air 11” Mid 2012. This MacBook Air uses a proprietary storage drive connector, and is therefore not compatible with common M.2 drives without the use of an adapter.

Before you perform this repair, if at all possible, back up your existing SSD. Then, either familiarize yourself with internet recovery or create a bootable external drive so you’ll be ready to install macOS onto your new drive and migrate your data to the new SSD.

Finally, we strongly recommend installing macOS 10.13 High Sierra (or a later macOS) before replacing the original SSD from your MacBook Air. Most new SSDs require updated storage drivers not found in versions of macOS prior to High Sierra.

    • Shut down and close your computer. Lay it on a soft surface top-side down.

    • Remove the following ten screws:

    • Two 8 mm 5-point Pentalobe screws

    • Eight 2.5 mm 5-point Pentalobe screws

    • The special screwdriver needed to remove the 5-point Pentalobe screws can be found here.

  1. Wedge your fingers between the display and the lower case and pull upward to pop the lower case off the Air.

  3. In this step you will disconnect the battery to help avoid shorting out any components during service. Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board.

Excellent instructions. Very easy to do. I used this screwdriver to remove the screws from the bottom of the case: https://www.amazon.com/gp/product/B00N1R...

and I used the Pentalobe-6 from this set to remove the screw holding in the OEM SSD:

After removing the stock drive, I installed a Samsung M.2 EVO 850 512Gb drive. It is working quite well. I used this adapter so that the M.2 drive fit in my 2012 Macbook Air:
