Apple reversed course this year, opting to allow for user-swappable memory on the new Mac mini. The procedure isn't as straight-forward as it could be, so AppleInsider walks you through it.
There are many configuration options when choosing your Mac mini between the processor, RAM, storage capacity, and an upgraded Ethernet port. Most of these cannot be changed and are soldered to the main board, but the RAM is upgradable post-purchase.
How to replace the RAM was one of the most frequent questions we received after our in-depth 2018 Mac mini review, so we are here with answers.
But look, here's the basic deal — you can break things and you will be sorry. You can destroy your new computer if you aren't careful, and it is not our fault. Read the procedure in full before you decide if this is something you want to do.
Importantly: this procedure does not void your warranty, however anything you break in the process does.
Also, keep the old RAM chips. If you need to bring your Mac mini back to Apple for any reason, they won't do a thing with it if your RAM is installed. So, if that's the case, put the RAM back in, before you head off to the Genius Bar.
What you need
To start, you need a few things including a TR6 Torx security screwdriver, T9 Torx screwdriver, P5 screwdriver, a plastic spudger, a pair of DDR4-2666, 1.2V, PC4-21300, unbuffered, non-ECC RAM sticks, and an anti-static wrist strap that you know how to use properly.
