Apple Sets Rosetta Deadline as Intel Macs Lose Support

Ahead of WWDC 2026, Apple says macOS 27 will be the final macOS release with general-purpose Rosetta support. At the same time, macOS 26 Tahoe is the last major version compatible with Intel-powered Macs—pushing remaining Intel hardware and legacy apps into a

On the morning of its June 8 keynote, Apple moved to close the chapter on Intel Macs—and with it, the comfortable compatibility cushion developers and IT teams have relied on for years.

In updated developer documentation ahead of WWDC 2026. Apple confirmed that macOS 27 will be the final release to include the full. general-purpose version of Rosetta. the translation layer that lets Intel-based apps run on Apple silicon Macs. The message is blunt in practice: developers get one last major macOS cycle to move remaining Intel apps to native Apple silicon support. and for users and IT teams still dependent on older apps or Intel Mac hardware. the window for easy compatibility is shrinking.

The software deadline arrives with a hardware deadline attached. Apple also confirmed that the current macOS 26 Tahoe is the final major operating system release compatible with Intel-powered Mac computers altogether. After that, macOS 27 will require Apple silicon hardware and will officially drop compatibility for the last remaining Intel machines.

Apple listed the models expected to be left behind by the upcoming update:

• 16-inch MacBook Pro (2019)
• 13-inch MacBook Pro (2020, Four Thunderbolt 3 Ports)
• 27-inch iMac (2020)
• Mac Pro (2019)

Those machines won’t receive major feature upgrades. Apple emphasized, however, that they “will continue to receive security updates for 3 years.”

For the devices that will be supported, Apple’s guidance points to continuity through modern hardware: macOS 27 is expected to support all Mac hardware powered by the M1 generation or newer. Apple also named the recently introduced MacBook Neo, which runs on the A18 Pro chipset.

Rosetta’s final phase is the other half of the same transition. Apple said Rosetta will remain available “through macOS 27” as a general-purpose tool to help developers complete the shift of their apps to Apple silicon. After that. only a limited version of Rosetta will survive—focused mainly on older. unmaintained games that rely on Intel-based frameworks.

Apple’s documentation also spells out what Rosetta is meant to do and what it is not. It was designed “to make the transition to Apple silicon easier” and is not meant to replace native app development. Rosetta automatically translates x86_64 instructions so Intel apps can run on Apple silicon, often without users noticing any operational difference. But the timeline now makes its temporary role harder to miss.

This migration, after all, has been years in the making. Apple’s move brings the company closer to completing a shift that began nearly six years ago with the introduction of its own custom Mac chips. Apple’s framing is that the transition has been smoother than earlier platform shifts largely because Rosetta let Intel applications keep running on newer hardware with minimal user effort.

Now, the latest guidance narrows the runway for teams that haven’t finished their updates. Developers who haven’t yet moved their software to Apple silicon have one final major macOS release before full Rosetta support disappears.

More details about macOS 27—including its official name, features, and the full list of supported devices—are expected during Apple’s WWDC.

There’s also a larger subtext hanging over the timeline: Apple has been pushing developers away from Intel compatibility for years. but it’s the simultaneous cutoff—first Intel Macs moving out of major OS support with macOS 26 Tahoe. then general-purpose Rosetta ending with macOS 27—that forces hard decisions on the remaining holdouts.
