I’ve an iMac 2017 model with HDD and no fusion drive. HDD has slowed down so I’m planning to make use of an exterior SSD. In my earlier query a beneficiant person advised me that in my mannequin of iMac Excessive Sierra will work higher as APFS don’t work nicely. I simply wish to know that if I exploit an exterior SSD to put in MacOS then can I set up newest model or use solely Excessive Sierra.
