If I purchase 3rd party RAM upgrade for this Late 2018 MacMini, and install it myself, will that run afoul of the T2 chip? I usually upgrade via OWC for myself and my clients. I am trying to clear the air for the 480 readers of my daily newsletter.
You should be OK doing so. I believe the T2 chip only time bombs major stuff like the logic board. Lots of people are having luck with the guide created to replace the RAM so I foresee no problems here. Mac mini Late 2018 Memory (RAM) Replacement
correct - the reason Apple soldered that SSD to motherboard - as if there would be T2 + possibility to to upgrade via M.2 - that would….. NOT work with any SSD - would p*ss off many people
After replacing the RAM, I won’t be able to upgrade Big Sur. However, the upgrade could be done after insert the old Ram. Is that related to T2 ?
