What reviewers say
Reviewers praised the brighter 5K display, stronger graphics and added Thunderbolt 3. They found it a more substantial upgrade for older machines than for recent iMacs. Accessible memory helped, but SSD and memory options were expensive and the fixed-height screen and rear ports remained limitations.
