RAM Upgrade
I have a 21.5 inch late 2013 inch iMac w/ the 2.7Ghz Intel i5 proc. I want to upgrade the RAM from the current 2x 4Gb DDR3 to something larger. I understand that this supposedly a non user suggested upgrade. I just want to know if I can put something larger than 8Gb DDR3's in each slot, and can I use an 1866 Mhz DDR3 instead of the 1600 that it says
iMac 21.5″, macOS 10.14
