The iMac with Apple silicon is a line of all-in-one desktop Macs made by Apple Inc. since 2021. The first major redesign of the iMac line since 2012, the case and internals were redesigned to use Apple's custom processors, starting with the M1 system on a chip. The Apple silicon iMac features a 24-inch screen in a thin aluminum enclosure, elevated off the resting surface by a foot, and comes in seven colors.

Apple started shipping the first Apple silicon iMacs on May 21, 2021. The line was revised in 2023 to use the Apple M3 chip, and in 2024 to use the Apple M4. Reception to the iMac has generally been positive; critics highlighted the design, ease of use, and portability as positive features, while the lack of ports and height adjustment, cost, and lack of a larger screen size were common criticisms.

Overview

[edit]

The Apple silicon iMac is an all-in-one personal computer, with the computer components integrated into an enclosure with the display. The Apple silicon iMac is the first major redesign to the line since 2012. In lieu of the two previous size options—21.5 inches (55 cm) inches and 27 inches (69 cm)—the Apple silicon iMac comes in a single 23.5-inch (60 cm) (rounded to 24-inch) display size.[1][2] The computer is flat-backed and 0.45 inches (11 mm) thick, with half the volume and roughly 30 percent smaller footprint than the 21.5-inch iMac. As it does not fit in the shrunken enclosure, the power supply is located externally and connects magnetically to the computer.[2][3] The display tilts on a hinge attached to its non removable metal foot; there is no way to adjust the display's height. A VESA mounting option is configurable at purchase.[4][5] Universal Serial Bus (USB) ports are located on the back of the machine, while the headphone jack and Gigabit Ethernet port, due to their size being thicker than the case thickness, are located elsewhere—the Ethernet port on the power supply, and the 3.5-mm audio jack on the left edge of the iMac.[2][4][6]

The screen is a Retina display, with a resolution of 4480 x 2520 pixels.[7] It is surrounded by white bezels shrunk by roughly half percent compared to its predecessor.[1][2] The majority of the computer components are found in a small chin below the display.[2] The computer comes in seven colors—silver, blue, green, pink, yellow, orange, and purple—in a two-tone finish, with a lighter pastel tint on the front of the computer, and a darker shade on the back.[1][2] The included peripherals and power cords are color-matched to the finish, as are the macOS operating software accent color and wallpaper.[6] Above the display is a 1080p-resolution webcam, with image signal processing performed by the Apple silicon. The iMac captures audio through an array of three microphones, and outputs sound through a six-speaker system that supports Dolby Atmos.[8]

The iMac comes in two different models. The cheaper models come with two Thunderbolt/USB4 ports next to the power button at the back edge of the computer,[9] and lack Gigabit Ethernet as standard. They also have lower-specced chips with fewer graphics processing unit (GPU) cores. The more expensive models add two USB-C ports, come with Gigabit Ethernet, have higher configurable storage options, and have keyboards with Touch ID authentication. In early revisions, some colors were also exclusive to certain models.[7][8][10] The memory and storage are soldered and not upgradeable, while other parts such as the speakers, ports, and webcam and modular and can be replaced if defective.[11]

Release

[edit]

On June 22, 2020, Apple CEO Tim Cook announced the Mac would transition from Intel processors to Apple-designed processors that use the ARM64 architecture, branded as Apple silicon. Apple announced a 24-inch iMac based on the Apple M1 system on a chip on April 20, 2021.[12] It was the first iMac available in multiple colors since the iMac G3, with Apple marketing manager Colleen Novielli saying the choice was made to make the new iMacs feel "light and optimistic"; CNET attributed the shift in part as a move away from minimalism and a return to nostalgia amid the work-from-home movement during the COVID-19 lockdowns.[13] Apple also suggested the variety of colors helped the machine feel at home in more settings, whereas the previous silver iMacs were found in offices.[14] Former Apple designer Jony Ive contributed to its development.[15]

The initial M1 iMacs featured 8-core processors with either 7 or 8 GPU cores, 256 GB solid-state drives, and 8 GB of random access memory, configurable up to 2 TB of storage and 16 GB of memory.[7] The iMacs shipped with a Magic Mouse 2 or Magic Trackpad 2 with a color-matching aluminum underside. It could 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 initially only shipped with the iMac.[16]

Apple announced updated iMac models on October 30, 2023. The new models feature the Apple M3 chip with 8 CPU cores and up to 10 GPU cores, faster Wi-Fi 6E and Bluetooth 5.3 connectivity, and up to 24 GB of memory.[17] The M3 chip adds support for improved graphics features, such as raytracing in hardware.[18] The design, pricing, and other features remain identical.[5] The line was revised again on October 28, 2024, with the Apple M4 chip. The M4 models feature modified colors, 16 GB memory as standard, an improved webcam that supports Center Stage, support two external displays, and come bundled with USB-C peripherals.[10][19]

Reception

[edit]

The Apple silicon iMac received generally positive reviews from critics. Ars Technica's Samuel Axon and PCMag's Joe Osborne considered the iMac a return to the product line's roots as a simple computer for consumers.[2][20] Reviewing the M1 model, PCMag's Tom Brant suggested the new iMac could define the next decades of desktop computing.[14] Reviews often highlighted its role as an approachable computer for families.[21][22] The reduced weight and size of the iMac made it easy to transport, with Jason Snell saying that while no one would use the iMac as a laptop it was far more mobile than its predecessor.[6] In contrast Dan Seifert, writing for The Verge, questioned whether a "a simple all-in-one desktop computer is something most people want or need at this point."[5]

The colorful redesign was generally praised as stylish and well-considered,[8][18][22] with TechRadar's Matt Hanson wrote that the "bold and modern" redesign had successfully refreshed a product that had become outdated.[23] Some reviewers felt that the white bezels were a step down from the black of its predecessors,[2][6][22][24] or that the bold look and bright colors were not for everyone.[25] Katie Collins from CNET said the design was a statement piece that served as a "symbol of hope" while working from home during the COVID-19 pandemic; and also considered this to be part of an anti-minimalism trend, an end to "austerity" in product design.[13] Technology blogger John Gruber predicted its design would stand the test of time.[26] Some reviews likened the design to a large iPad on a stand.[11][27] Some reviews lamented the bulky external power brick, while others appreciated the addition of ethernet on the brick allowed for reduced desktop clutter.[6][4][14] Other points of praise were the improved webcam, speakers, and microphones.[4][6][14][21]

The iMac's speed was positively noted,[28][29] with Engadget testing finding the machine's responsiveness waking from sleep mode or starting up welcome,[21] and Monica Chin noting the iMac achieved higher single-core Geekbench performance scores than any previous iMac, including the iMac Pro.[8] Benchmarks and testing found the Apple silicon iMacs performed similarly to other Apple computers with the same chip.[14][24] The main weakness of the machines was noted as its graphics capabilities,[5][9][30] though some reviews of the M3 models were surprised by its games performance.[28][29] Tom's Guide and Digital Trends found the entry-level iMac disappointingly limited, and the added costs to add Touch ID unreasonable.[4][25] PCMag, USA Today and others felt the machine quickly became pricey for the specs, as a similarly-performing Mac mini could be had for half the price.[14][21][28][30] Snell found that the entry-level processor kept the iMac from being a choice for users who needed more power,[6] and some publications wished for a higher-end and larger "iMac Pro".[5][25][30]

Reviews found the iMac's display bright and clear,[14][21][29] although in bright environments the glossy screen could cause glare.[28][31] Wired and others criticized the removal of the larger 27-inch screen size, finding the smaller screen occasionally cramped.[32][5] The continued lack of height adjustment on the display was faulted.[9][21][22][25] Other complaints included the paltry number of ports and their placement,[4][14][29] and the low amount of starting memory and storage in the entry-level machines.[22]
