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 8-core GPU, 16GB memory, 256GB storage. “Since” is the first day MacIQ read that figure; “earlier” figures were each read from the date shown.

Apple’s UK store page for the base configuration (Apple M4 chip, 10-core CPU, 8-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. MacIQ read a selection of the Archive’s captures, not every one. 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.
