Overview

The 2021 Apple iMac (MGPL3LL/A) represents a fundamental reimagining of the all-in-one desktop, built around the Apple M1 chip's unified architecture. The 8-core CPU and 8-core GPU share 16GB of unified memory, enabling the kind of seamless multitasking and creative performance — from photo and video editing to software development — that previously required significantly bulkier hardware. Paired with a 1TB SSD, this configuration eliminates storage anxiety and ensures rapid file access across even large project libraries. The 24-inch 4.5K Retina display renders over 11 million pixels with P3 wide color gamut coverage and 500 nits of brightness, making it a capable screen for color-accurate creative work as well as everyday computing.

Beyond raw performance, this iMac excels in the details that define daily use. The 1080p FaceTime HD camera leverages the M1's image signal processor to deliver dramatically improved video call quality with better noise reduction and exposure handling. A studio-quality three-microphone array captures clear voice audio, and the six-speaker sound system with spatial audio support fills a room without external speakers. Connectivity includes two Thunderbolt/USB 4 ports, up to two USB 3 ports, Wi-Fi 6, and Bluetooth 5.0. The entire package sits in a chassis just 11.5 mm thin, available in vibrant color options, and ships with a color-matched Magic Mouse and Magic Keyboard.
