Answer to "New iMac 5k 2017 CPU is Upgradable?"oops! why I can’t log-in to ifixit by Google account anymore?! I'm a bit confused! Now in macOS Mojave, is it possible to do that? or hardware doesn’t accept it! Anyway. I’m going to bring my iMac 5K 2017 to London apple store and ask them to instal high-end CPU that it’s possible into it. :) But, if I can replace i5 to i7 8700K, I will do that by myself. I just wanted to ask is it possible with 2017 iMac hardware condition or not. Because, I already knew that Apple will release an update for 8 generation Intel CPUs.
