This 24-inch iMac with Retina 4.5K display is finished in Silver, one of Apple's signature all-in-one colourways that carries through to the display's chin and the matching keyboard/mouse. It's built around Apple's M4 chip with a 10-core CPU and 10-core GPU, 24GB of unified memory, and a 512GB SSD -- Apple's unified memory architecture means that memory pool is shared directly between CPU and GPU tasks rather than split into separate system and video RAM. The 4.5K Retina display (4480x2520) supports True Tone and wide P3 colour, backed by a six-speaker sound system and a studio-quality three-microphone array, plus a 1080p FaceTime HD camera for video calls -- genuinely strong built-in AV hardware for an all-in-one aimed at everyday computing, study, and light creative work. Being the higher-tier port configuration (Model A3137), it carries four Thunderbolt/USB 4 ports and Gigabit Ethernet built into the power adapter, for owners who need to connect more peripherals or a wired network without a hub. It ships with macOS preinstalled (Model A3137).
