My Mac can't update to macOS 27

macOS 27, released on 14 September 2026, is the first that only runs on Macs with Apple chips (M1 and later). No Mac with an Intel processor can install it, and most had already been left behind earlier.

How to tell whether your Mac is Intel

Apple menu (the apple at the top left) → "About This Mac". If it says "Processor" and mentions Intel, it's an Intel Mac. If it says "Chip" and Apple M1, M2, M3 or later, your Mac does get macOS 27 and this page isn't about you.

Apple publishes no official policy, but in practice it only ships security patches for the current macOS and the two before it: today, macOS 27, 26 Tahoe and 15 Sequoia. Some models split by configuration: check yours in "About This Mac".

What you can do

  • If your Mac is on 15 Sequoia or 26 Tahoe: nothing for now. It still gets security patches, just no new versions.
  • If it's on an older version: using Firefox, which still updates from macOS 10.15 Catalina, protects at least the browser.
  • Buy a Mac with an Apple chip, if you need to stay on macOS.
  • Install Linux on this Mac: the whole system gets updates again. Today the kit covers 2012 to 2015 Macs and the 2017 MacBook Pro without Touch Bar; the 2016 to 2020 models with a Touch Bar or T2 chip not yet, and in the check you can leave your email so we let you know.

If you want to keep using this Mac with everything up to date

Linux is a free system that still gets updates on these Macs. With it you get up-to-date apps like Chrome, Steam, Signal or VS Code again, and security patches for the whole system. The ResucitaTuMac Kit installs it for you with a wizard, in English or Spanish, without sending the Mac anywhere: you can keep macOS alongside and choose at power-on.

It's for Intel Macs from 2012 to 2015 and the 2017 MacBook Pro without Touch Bar. One-off payment of €24.99.
