Apple announced that macOS 26, also known as macOS Tahoe 26, will be the last version to support Intel-based Macs. The final Mac with an Intel processor was the previous-generation Mac Pro, succeeded by the M2 Ultra-powered Mac Pro in 2023. The transition to Apple Silicon began with the M1 series in 2020 and continued with the M2, M3, and M4 series. Critical security updates for Intel-based Macs will continue for a limited time but will eventually cease. macOS 27 will only support Apple Silicon Macs with M1 and later processors. Not all Macs running the current version, Sequoia, will be eligible for the Tahoe update; only those with Intel's ninth-generation Coffee Lake and Cascade Lake-based Xeon-W processors can run Tahoe. This includes specific models like the Mac Pro (2019) and MacBook Pro (16-inch, 2019). Many Intel Macs, including various 2018 and older models, will not be able to upgrade to Tahoe. Apple's transition from Intel began in 2005, moving from PowerPC processors.
