Apple’s ongoing transition to Apple silicon has been largely smooth, but a looming change with the release of macOS 28 in 2027 is raising concerns for users of older software. The discontinuation of Rosetta 2 – the translation layer allowing Intel-based apps to run on Apple silicon – is prompting questions about compatibility, particularly for those reliant on desktop applications like Sonos. The future of Rosetta 2 support is now a key consideration for software developers and users alike.
The issue came to the forefront recently as beta testers of macOS Tahoe 26.4 began receiving warnings about apps that will grow incompatible after macOS 27. This notification system, introduced with the 26.4 beta, is designed to give users time to find updated Apple silicon-native versions of their software. As one user expressed in a Sonos community forum, the potential loss of the desktop app and reliance on a web-based alternative is particularly concerning for those with limited internet access.
The Complete of Rosetta 2: A Timeline
Apple first announced its intention to phase out Rosetta 2 support at WWDC25, stating that it would be fully supported through macOS 27. According to 9to5Mac, macOS 28, slated for release in the fall of 2027, will largely discontinue Rosetta 2 functionality. But, Apple has indicated it will maintain a limited subset of Rosetta functionality to support older, unmaintained gaming titles that rely on Intel-based frameworks.
The current macOS 26.4 beta includes a popup notification when launching apps that depend on Rosetta 2, alerting users to the impending incompatibility. This proactive approach aims to encourage developers to update their applications for native Apple silicon support. AppleInsider reports that macOS Tahoe 26.4 specifically warns users if their favorite Intel-only apps won’t function in macOS 28.
Impact on Sonos Users
The Sonos community member’s concern highlights a broader issue: the potential disruption for users who prefer desktop applications over web-based alternatives. For individuals with unreliable or slow internet connections, a web app may not be a viable solution. The Sonos user specifically noted their preference for the macOS app and apprehension about relying on the web app due to poor internet availability. This situation underscores the importance of software developers prioritizing Apple silicon compatibility for their desktop applications.
While the focus is on Sonos, the issue extends to numerous other applications still relying on Rosetta 2. The transition to Apple silicon has been largely successful, but pockets of legacy software remain, and the impending end of Rosetta 2 support will force users and developers to address these compatibility challenges.
What’s Next for Apple Silicon and App Compatibility?
As macOS 27 approaches in September 2026, the pressure will mount on developers to ensure their applications are natively compatible with Apple silicon. Apple will continue to provide security updates for Intel-based Macs for three years after the release of macOS 26, but novel features and full compatibility will be reserved for Apple silicon. MacRumors details that Apple will also continue to support older gaming titles and software running Intel binaries in Linux VMs beyond macOS 27.
The coming months will be crucial for determining which applications will make the transition to Apple silicon and which will be left behind. Users are encouraged to check with software developers to confirm compatibility plans and explore alternative solutions if necessary. The future of app compatibility on macOS hinges on developers embracing Apple silicon and ensuring a seamless experience for all users.
