IMac (2021)

🇲🇴 "M1 is a gigantic leap forward for the Mac, and today we’re excited to introduce the all-new iMac, the first Mac designed around the breakthrough M1 chip,” said Greg Joswiak, Apple’s senior vice president of Worldwide Marketing. With its striking design in seven stunning colors, its immersive 4.5K Retina display, the best camera, mics, and speakers ever in a Mac, and Touch ID, combined with the amazing performance of M1 and the power of macOS Big Sur, the new iMac takes everything people love about iMac to an entirely new level."

The 2021 iMac is an iMac desktop computer designed and developed by Apple. It is the first iMac model based on the Apple M1 processor and the first desktop computer to support Touch ID. The Mac was released on May 21, 2021.

Features
In the 2021 iMac, Apple debuted the ARM64 architecture Apple Silicon M1 Soc, which integrates the Mac's CPU, graphics processor, USB and Thunderbolt controllers, Secure Enclave, ML Neural Engine, image signal processor, and audio processing hardware. The Apple M1 system on a chip uses 5-nanometer process technology and a unified memory architecture different from other industrial architectures. The M1 features a 3x faster 8-core CPU consisting of 4 high-performance cores and 4 high-efficiency cores. In addition to to a faster 16-core architecture ML Neural Engine that executes 11 trillion operations per second.

The 2021 iMac includes 24-inch 11.3 million-resolution Retina screen display with a billion colors, 500 nits of brightness, anti-reflective coating, and P3 wide color gamut technologies, as well as a four-speaker landscape audio system, a 1080p FaceTime HD camera, and a built-in camera with improved noise reductions, dynamic ranges, white balance,s and auto exposures.

The Mac logic board and thermal architecture were thinned, so as to enable a practically concealed section side profile. The Mac is equipped with two Thunderbolt ports, two USB-C ports, and a redesigned 1Gbps Ethernet port in the power adapter. The Mac added support for Touch ID and repositioned the headphone jack to its left. The Mac is 50% lighter than its predecessor.

Manufacturing
The Mac uses low-carbon aluminum enclosure, 100% recycled tin in the solder of its main logic board, 100% recycled, clean rare earth elements for the magnets in its speakers, fan motor, and power connector, and 35% recycled plastic in many components.
