Apple is planning a near-term update to its 24-inch iMac, replacing the current M4 chip with a next-generation M6 chip. The refresh is expected before the end of 2026, though it won’t bring major visual upgrades beyond possibly new color options.

What’s Changing: M6 Specs & Product Cycle
The incoming M6 chip will introduce a higher memory bandwidth—200 gigabytes per second—and a reworked memory architecture. Graphics performance should also get a bump via a 12-core GPU. ([appleinsider.com](https://appleinsider.com/articles/26/08/23/m6-imac-refresh-expected-before-the-end-of-2026/)) This generation, however, appears to be a brief bridge; M6 is expected to have a shortened lifespan of roughly six months, rather than the usual year-or-more lifecycle seen with past Apple Silicon releases.

Notably, Apple seems to be skipping “Pro,” “Max,” and “Ultra” variants for M6. All signs point to a single, base M6 chip being used initially. Those higher-end versions will reportedly return with the launch of the M7 generation, which is slated for the first half of 2027; the Ultra version might not show up until 2028.

Design & Release Timeline
The design of the refreshed iMac is expected to stay almost identical to the current 24-inch M4 model, which was last majorly updated in 2021 when Apple introduced the modern design. Expect only minor tweaks—primarily color updates, rather than a full redesign. ([appleinsider.com](https://appleinsider.com/articles/26/08/23/m6-imac-refresh-expected-before-the-end-of-2026/))
While there’s been talk of an OLED version of the iMac in the future, any such model appears to be far off. In the near term, the main event is the imminent M6 iMac release. ([appleinsider.com](https://appleinsider.com/articles/26/08/23/m6-imac-refresh-expected-before-the-end-of-2026/))
The timeline is clear: the M6 iMac should arrive before the end of 2026, and the M7 generation will follow in early 2027. Given the short duration of the M6 cycle, customers weighing upgrades may want to consider whether waiting for M7’s more extensive jump is worth it.

Analytical Angle: This limited refresh reflects Apple’s cautious rollout strategy amid rapid advances in chip-level AI features. The move to raise memory bandwidth and improve graphics via 12-core GPU in the M6 indicates Apple is laying groundwork for AI and graphics workloads that demand higher throughput. But by restraining design changes, Apple preserves flexibility to pivot with M7, which is likely to unlock more aggressive performance gains. For buyers, the decision comes down to assessing whether the M6’s modest lift is enough to justify upgrading now, or whether holding out for the more significant leap with M7 in 2027 might deliver more value.
