While previously there were rumors of an M5 version, multiple reports now point to a new iMac arriving this fall powered by Apple’s M6 chip. All we have to go on are rumors and Apple’s previous habits, but the current expected M6 iMac release date is fall 2026… probably October. As for a possible larger display, Apple once made the 27-inch iMac Pro, and those who remember it fondly dream of another high-end all-in-one desktop from Apple.
