General information
Apple has begun warning owners of Intel-based computers about end of support: in macOS Tahoe 26.4 messages have appeared for applications that run through Rosetta 2. The message indicates that after the release of the next major version — macOS 27 — such apps may no longer work. MacRumors was the first to report the changes.
What exactly changed in macOS Tahoe 26.4
When a user launches an application that is emulated via Rosetta 2 (that is, written for Intel processors), the system now shows a warning about limited support in future releases. In practice, this is a signal to developers and end users: it's time to move to native builds for Apple silicon or look for alternatives.
"After macOS 27 is released, it will no longer work."
— MacRumors
Why this matters (a frame for the reader)
This is not just a technical formality. Three things matter to users: application compatibility, security updates, and cost of ownership. If key tools (editors, professional software, government services) remain unsupported, workflows will need to change or investments in new hardware will be required.
From the perspective of national resilience: Ukrainian organizations and businesses that rely on Macs in their work (media, creative studios, IT teams) should proactively plan migration to avoid downtime and security risks.
Timeline and related news
Apple officially plans to release macOS 27 in September 2026. The transition to Apple silicon began with the launch of the first M1 in 2020 — since then the company has been gradually dropping support for older models. The reports also note that in 2025 Apple declared three MacBook models obsolete. Meanwhile, media outlets are reporting rumors of a possible budget MacBook with an A18 Pro chip that could be announced on March 4 — this might be an option for those planning an upgrade without large expenses.
What to do now — practical steps
- Check which applications you run through Rosetta 2 and whether there are native builds for Apple silicon.
- For organizations: take inventory of devices and prioritize updates of critical software and hardware.
- Make backups and test key workflows on beta versions or on test machines with Apple silicon to avoid surprises in the fall of 2026.
Conclusion
This message is not the end of the Mac era, but a signal that the transition period is ending. For many users this will be a planned migration; for others it will be a reason to review budgets and safeguard business processes. Whether to wait for cheaper Apple models or switch now depends on your tools and risk appetite. But it's better to decide in advance than under the pressure of release deadlines.
