Apple Ends 20-Year Intel Mac Era With macOS 26, Keeps Security Updates for 2 More Years

Q: With millions of Intel Macs losing support, what is the real lifespan of a modern Apple computer?

A modern Apple computer’s practical lifespan is usually about 7 to 9 years, though many remain physically usable for longer. What matters most is not when the hardware dies, but when Apple stops providing major macOS upgrades and security patches. For Intel Macs, that window is now closing fast. macOS 26 Tahoe is the last major release for Intel models, and macOS 27, due in fall 2026, drops Intel support entirely. The newest supported Intel Macs from 2018 to 2020 will still get security and Safari updates for a limited period, in some cases until 2027 or 2028. That means the best-case supported life for the last Intel Macs is roughly 7 to 8 years from launch. After that, they may still work, but they become harder to recommend for everyday use because of security risk, app incompatibility, and the end of Rosetta support for Intel-only software on newer Apple Silicon systems. Apple Silicon Macs appear likely to last longer in practical terms. The earliest M1 models from 2020 are still fully supported in 2026, and Apple’s current trajectory suggests 8 to 10 years of useful life is realistic, especially for lighter workloads. They also run cooler, have fewer hardware failure points than Intel-era designs, and are better positioned for future macOS features. The real answer is that a Mac’s lifespan is defined by support, not survival. For Intel Macs, that era is ending around the 7-to-8-year mark. For Apple Silicon Macs, the safer expectation is closer to a decade.

macOS 26 Tahoe is the final full release for Intel Macs, with macOS 27 later this fall ending feature support for the remaining compatible models.
Two years of security and Safari updates will still follow for the last Intel Macs that can run macOS 26, while parts of Rosetta will remain available on Apple Silicon for some Intel app compatibility.
Apple’s Intel transition began as early as 2000 with the internal 'Project Marklar' effort to run Mac OS X on Intel chips, years before the first commercial Intel Macs shipped.
The move closes a partnership that Apple says once made Macs dramatically better, before its own silicon strategy ultimately displaced Intel across the lineup.
