I want to upgrade my 27" iMac to 32GB, but I don't know which memory to buy. I believe it has 4 slots with a max of 8GB per slot. However, Crucial dot com says that ct2k4g3s160bjm and ct2k4g3s160bm are both compatible.
What's the difference between the BJM and BM memory? Anyone know?
She currently uses an iMac from late 2011 and we just upgraded the MacOS to High Sierra. She is a kindergarten teacher and uses it quite a bit for work related projects.
I am looking at the mid-level model for $1299 with 4K display and hard drive upgrade...
High Sierra has been available for a short while.
