The iMac with Apple silicon, also known as the iMac M1, is a Macintosh desktop computer designed, developed and marketed by Apple Inc. The first iMac with Apple silicon, a redesigned 24-inch model based on the Apple M1 ARM-based system on a chip, was released on May 21, 2021.
On June 22, 2020, Apple CEO Tim Cook announced the Mac would shift from Intel processors to Apple's own in-house designed processors that use the ARM64 architecture, branded as Apple silicon. On April 20, 2021, Apple announced a 24-inch iMac based on the Apple M1 system on a chip.
The iMac with M1 features a 4480-by-2520 (4.5K) built-in display, 1080p FaceTime camera with an improved image signal processor and three-microphone array, and a six-driver stereo speaker system with a pair of force-cancelling woofers and a tweeter per side, that supports Dolby Atmos and spatial audio. It also adds support for Wi-Fi 6, USB4/Thunderbolt 3, and 6K output to run the Pro Display XDR. External display support is reduced to one display over USB-C/Thunderbolt; the previous 21.5-inch Intel-based model could drive two 4K displays over USB-C/Thunderbolt. The models also include a magnetic power plug and external power supply that can be configured with a Gigabit Ethernet port.
The iMac with M1 ships with a Magic Mouse 2 or Magic Trackpad 2 with a color-matching aluminum underside. It can be configured with one of three updated Magic Keyboards with rounded corners: a standard version, a version with a Touch ID sensor, and an extended layout version with a numeric keypad and Touch ID. The Magic Keyboards with Touch ID are compatible with other Mac computers with Apple silicon but only ship with the iMac.
The iMac with M1 is the first iMac with a major redesign since 2012, with slimmer bezels, a flat back and seven color options, the same colors used in Apple's first official logo. It is the first iMac available in multiple colors since the iMac G3. Jony Ive contributed to its design.
