Can you upgrade to an SSD in a NEW iMac before turning it on?
It may sound like a silly question but please bear with me.
I’ve managed to get my hands on a brand NEW unopened 21.5” 2017 4K iMac (featuring a fusion drive) and would like to perform a full system upgrade (blade SSD, 2.5” SSD and RAM) before even turning it on for the first time.
My question concerns installing a fresh copy of MacOS on a system upgraded as such. Would I need to create a bootable drive before hand (basically turn the system on first)? Or does the Internet Recovery feature exist within the BIOS?
Cette question est-elle utile ?
