macOS Tahoe 26.4 Alerts Users of Apps Obsolete After Rosetta 2 Ends
Apple’s latest operating system, macOS Tahoe, marks a significant milestone in its transition from Intel-based Macs to Apple silicon. The new version, set to launch with updates, signals the end of support for Intel Macs as Apple moves forward.
macOS Tahoe 26.4: Transition Alerts
Beginning with macOS Tahoe 26.4, users will receive notifications regarding apps that rely on Rosetta 2. When these apps are launched, a popup will appear informing users that support for Rosetta 2 will cease after macOS version 27.
End of Support for Intel Macs
Apple confirmed that future versions of macOS will not be compatible with Intel machines. This decision was first announced during the WWDC event in June 2025. The transition began with the introduction of the M1 Macs in 2020, culminating in the Apple silicon Mac Pro three years later.
- Transition Start: 2020 with M1 Mac
- Transition Completion: 2023 with Apple silicon Mac Pro
- Next Version Launch: macOS 27 in September 2026
Support for Legacy Apps
Despite phasing out support for Intel Macs, Apple plans to continue supporting older gaming titles that use Rosetta. There may also be future security updates for software running Intel binaries in Linux virtual machines (VMs).
The Future of macOS
With the impending release of macOS 27 in September 2026, users should prepare for a complete transition away from Intel architecture. This shift showcases Apple’s commitment to its M1 and subsequent silicon chips.
As new updates are revealed, users are encouraged to stay informed about the changes to ensure software compatibility and security.
