The only reason we don't rate it as the number 1 iMac for image or video editing is, like it's M1 MacBook cousins, you can't spec more than 16GB or RAM. The 24-inch iMac is also beautifully slim and can be had in 7 different color options, making it a true object of desire. Its price is more palatable than that of its 27-inch sibling, and it packs Apple's superb M1 System on Chip, which is both blazing fast and yet super efficient and cool-running. Alternatively, there's the new 2021 24-inch iMac.
