In 2019 how many apple products have user (or technician for that matter) upgrade-able anything? honest question. I'm not a Mac person and all I see is anecdotal reports of "soldered in RAM here" "fully bonded case there" etc.
Both new Mac mini and 27" iMac have upgradeable RAM.
The 27" iMac used to have upgradable RAM, but the text for the new version says "configurable to 64 GB", not "upgradable" like it used to. I'd love to be proven wrong, though, I'm considering getting an iMac.
Unless something changed with today's update, it should be upgradeable via a hatch on the back of the machine. I upgraded my 2018 model to 40GB less than a year ago.
