Which Macs can still take more memory

Memory upgrades ended for most of the Mac line when Apple began soldering RAM to the logic board, and they ended completely with Apple silicon, where the memory sits on the same package as the processor. Knowing exactly which machines still have sockets saves buying a module that will never fit.

Can I add RAM to an M1, M2 or M3 Mac?

No. Apple silicon uses unified memory built into the same package as the chip, so the amount chosen at purchase is permanent for the life of the machine. There are no sockets and no modules. If a machine is short of memory, the practical options are reducing the workload, adding fast external storage so swap performs better, or moving to a higher specification machine.

Which Macs still have user accessible memory slots?

The 27-inch iMac from 2012 through 2020 has a rear access door with four SO-DIMM slots. The 2010 to 2012 non-Retina MacBook Pro and the 2010 to 2011 MacBook Air era Mac mini take standard SO-DIMMs under the bottom cover. The 2018 and 2020 Intel Mac mini has slots but they are behind a full strip down. The Mac Pro takes registered DIMMs. Every Retina MacBook from 2013 onward has soldered memory.

Does mismatched RAM cause problems on a Mac?

Macs will run mismatched modules, but they drop to the speed and timings of the slowest stick and lose dual channel performance if the pairing is uneven. On the 27-inch iMac the slots are paired, so two matched modules in the correct pair of slots outperform four mismatched ones. If a Mac beeps three times at startup and shows no display, that is the memory error tone and it means a module is not seated or is not compatible.
