Chosen Solution
Adding memory manually! Is that possible?
Here’s an image of internals
Both the RAM and Flash SSD are high density BGA chips and as the board is so dense it is impossible to alter it without damage! It would also cost more than buying a new system!
It’s somewhat possible as long as Apple didn’t write down the memory configuration encrypted. However you’ll be dealing with package-level soldering rework, which is a whole new game, even more difficult than previous versions where RAM chips are soldered onto the logic board.
Hi Maby you could try a external thunderbolt Ssd drive with macOS installed
