Apple launched the 24-inch iMac last year in April with an all-new design and its custom chip. However, the company was planning to add more features to the mix. We are now discovering that Apple considered bringing Face ID to its 24-inch iMac with an M1 chip. The revamped design could have been altered if Apple did adopt Face ID in the M1 iMac. Scroll down to read more details on the subject.

It was reported in the past that Face ID will be coming to the Mac lineup in the future. Now, it was reported by Bloomberg's Mark Gurman in his Power newsletter that Apple considered bringing Face ID to the M1 iMac. Gurman mentioned that Face ID was "in the cards for the original M1 iMac." It is not yet clear what made Apple ditch the idea since it would have made the entire authentication process more natural and easy compared to Touch ID in the new Magic Keyboard.
