I am looking to buy a 27inch iMac, but planning to buy with 8gb memory, so that i can upgrade RAM myself. However after clicking a few links to amazon from a few different popular youtube review videos, I've found a handful of people saying that the Ram basically messed up their iMacs after installation. I'm very concerned about buying Ram from a third party now, as I'm unsure which websites will surely sell the correct Ram i need for a 2019 27 inch iMac. Does anyone have any advice or suggestions?
Thankyou.
