Each figure is from the source marked¹ unless it carries its own number.

Drawn to scale from the published dimensions below: the front face. Outline only — the corner radius, where the display sits in the face and the stand’s width are our drawing conventions, not measurements; the display rectangle is Apple’s diagonal at its aspect ratio.

Read 3 November 2026. CeX is one UK retailer; its used and trade-in figures are shown at its condition grades for the base configuration: M4 with 10-core CPU and 10-core GPU, 16GB memory, 256GB storage. “Since” is the first day MacIQ read that figure; “earlier” figures were each read from the date shown. We hold no stock and take no commission.

Apple’s UK store page for the base configuration (Apple M4 chip, 10-core CPU, 10-core GPU, 16GB memory, 256GB storage), as the Internet Archive saved it. Each row runs from the first to the last Internet Archive capture MacIQ read at that price; the price may have held before and after. A price changed some time between the last capture read at one price and the first read at the next, so no day is given. A “From” price is the store’s starting price for the chip option; the base configuration is the lowest one listed under it. Read 18 October 2026.
