In 2020, Apple introduced the M1 chip, the first of the family of Apple silicon chips that now power the entire Mac lineup. At the time, Apple said it would “continue to support and release new versions of macOS for Intel-based Macs for years to come.”
Since then, it has become clear that Macs with Apple silicon are notably better than Intel-based Macs in nearly every way, and we’re now up to the impressive M4 chip family. Nonetheless, some people continue to hold onto their Intel-based Macs. Now we know precisely when those Macs will ride off into the sunset. Intel-based Macs had a good run, but it’s time to move on to Macs with Apple silicon.
macOS Support for Intel-based Macs
During WWDC 2025, Apple announced that macOS 26 Tahoe will be the last version of macOS to support Intel-based Macs, specifically these four models:
- 16-inch MacBook Pro from 2019
- 13-inch MacBook Pro with four Thunderbolt ports from 2020
- 27-inch iMac from 2020
- Mac Pro from 2019
macOS 27, expected in 2026, will run only on Macs with Apple silicon. However, the Intel-based Macs listed above will continue to receive security updates for macOS 26 for another two years. That means that all Intel-based Macs will have lost security viability by 2028.
How can you determine the type of Mac you have if you’re unsure? Choose About This Mac from the Apple menu and look at the Processor or Chip line.
Rosetta 2 Support for Intel-based Apps
There’s another aspect to Apple’s waning support for Intel-based Macs: Rosetta 2. The Rosetta translation environment allows apps written for Intel-based Macs to run on Macs with Apple silicon. The process is almost transparent because macOS downloads Rosetta the first time it needs it, and after that, Intel-based apps just work. They may be slower than native Apple silicon apps, but Apple’s M-series chips are so fast that the translated apps often run faster than on Intel-based Macs.
During WWDC, Apple published documentation clarifying the future of Rosetta. Apple plans to keep Rosetta available in its current state in macOS 26 and next year’s macOS 27. After that, however, Apple says it “will keep a subset of Rosetta functionality aimed at supporting older unmaintained gaming titles that rely on Intel-based frameworks.”
Given that Apple silicon has been the future since 2020, nearly all developers have updated their apps to run natively on the M-series chips. Very few actively maintained apps still require updates; Rosetta is primarily useful for those who rely on obsolete apps or older versions of current apps.
How can you find out whether an app you rely on is Intel-based? Open System Information (it’s in your Applications folder, nested in the Utilities folder), click Applications in the sidebar, click the Kind column header, and then scroll to find all the apps listed as Intel. To find out where one of these apps is stored on your Mac, select its listing and look at the Location field at the bottom of the window.
What All This Means
There’s a difference between what’s possible and what’s recommended.
Apple’s announcements draw a line in the sand at 2028 for when it will be too dangerous to continue using the last batch of supported Intel-based Macs. Older Intel-based Macs will cease to receive security updates even sooner—two years after they are no longer supported by macOS. If budget or compatibility with obsolete software or hardware prevents you from upgrading to a Mac with Apple silicon, it is possible to limp along with an Intel-based Mac for a bit longer.
Similarly, Rosetta will make it possible for you to continue using an obsolete Intel-based app on a Mac with Apple silicon through macOS 27, which will cease to receive security updates in 2029. Old games may continue to work for longer.
If we don’t sound enthusiastic about those possibilities, we’re not. Even the very first M1-based Macs outperform Intel-based Macs, and the performance difference is far wider with today’s M4, M4 Pro, and M4 Max chips. You aren’t doing yourself any favors by hanging onto an Intel-based Mac if you can afford to buy a new one.
Because so much time has passed, it’s likely that any Intel-based app that has not already been updated to run on Apple silicon will never be updated, so we recommend that you start looking for a replacement.
With both hardware and software, the longer you wait, the more problems you’re likely to encounter when upgrading. In part, that’s because both professional and community expertise fades with time—people who solved the problems you’ll encounter did so years before and may no longer remember the details. We also often see small conversion utilities built to help with transitions, but those tend to disappear or stop working after most people have moved on.
Most businesses upgrade their Macs every three to five years because the frequency of problems in that time frame increases to the point where employee downtime and maintenance and consulting costs outweigh the cost of upgrading. That financial equation is less evident to individuals, but it applies similarly.
So if you’re still using an Intel-based Mac or app, you now have a firm end date. But seriously, don’t wait that long.
