macOS 27 Ends Intel Mac Support, Requires Apple Silicon
macOS 27 Golden Gate officially ends Intel Mac support. Only Apple Silicon Macs (M1 and later) are compatible. Security patches provided for about two more years.
On June 8, during the Worldwide Developers Conference keynote, Apple announced details of the next macOS, “macOS 27 Golden Gate.” The biggest change is the complete end of support for Macs with Intel processors. Only Apple Silicon models—those with the first-generation M1 chip, released in late 2020, and later—can run this OS.
Apple had already hinted at this transition at last year’s WWDC. With this announcement, the era of Intel-based Macs, which lasted about 20 years, comes to an end.
Background of Intel Mac Support Termination
Apple began its transition from Intel to its own Apple Silicon in 2020. Originally aiming to complete the shift in two years, the company ultimately spent about six years gradually phasing out Intel Macs.
According to Ars Technica, macOS 27 Golden Gate removes most of the code for Intel Macs. This approach is similar to when Mac OS X Snow Leopard ended PowerPC support in 2009. By removing Intel code, it becomes practically impossible to force the new OS to run on Intel Macs using third-party tools like OpenCore Legacy Patcher.
macOS 27 Compatibility List
Apple’s published compatibility list for macOS 27 Golden Gate includes no Intel Mac models at all. Only the following Apple Silicon Macs are supported:
- MacBook Air (M1 and later)
- MacBook Pro (M1 and later)
- Mac mini (M1 and later)
- Mac Studio (M1 Max and later)
- Mac Pro (M2 Ultra and later)
- MacBook Neo (all models)
- iMac (M1 and later)
Even the original M1 model from 2020 works without issues. However, some Apple Intelligence features require newer hardware. Basic Apple Intelligence features are available on all Apple Silicon Macs, but more advanced on-device models require an M3 or later Mac with at least 12 GB of RAM.
Impact and Grace Period for Intel Mac Users
Users running macOS 26 Tahoe on Intel Macs will receive security updates and Safari patches for about two years after the release of macOS 27 Golden Gate. Those using macOS 15 Sequoia on Intel Macs will get an additional year of updates.
In other words, Intel Mac users unable to upgrade to the latest OS will not be completely abandoned. Apple is considering a gradual transition and will continue providing support for a certain period.
Rosetta 2 Will Be Maintained for Now
As for compatibility with Intel Mac apps, the Rosetta 2 translation layer will work with macOS 27. This allows applications written for Intel to continue running on Apple Silicon Macs.
However, Apple has indicated that it will gradually restrict Rosetta 2’s functionality in future macOS releases. In the long run, it is expected to be limited primarily to supporting older games that include Intel code. Users who depend on business-critical Intel apps should start planning their migration early.
Beta and General Release Schedule
The first developer beta of macOS 27 Golden Gate was released alongside the WWDC keynote. A public beta is scheduled to be available in July, with the final version arriving in fall 2026.
Editorial Opinion
Short-Term Impact
The end of Intel Mac support directly affects corporate IT departments. Organizations that purchased high-end Intel Macs in 2019–2020 will now have to decide whether to continue operating for two years with only security patches, or replace all machines with Apple Silicon Macs at once. A surge in Mac replacement demand is expected in 2026, and the resale value of used Intel Macs is likely to drop sharply. Meanwhile, sales of Apple Silicon Macs will accelerate further.
Long-Term Perspective
This transition means Apple has established a system where it has complete control over hardware and software. In the Intel era, chip roadmaps depended on Intel, but now Apple can optimize the OS for its own custom chips. Over the next one to three years, OS optimization exclusive to Apple Silicon could further improve battery efficiency and security. Additionally, the long-term restriction of Rosetta 2 will provide a strong incentive for the developer community to migrate to Apple Silicon-native apps. This trend is welcome as it enhances the health of the macOS ecosystem.
Questions from the Editorial Team
When will Rosetta 2 be completely phased out? Apple has said it will be “restricted in future releases,” but no specific timeline has been provided. Corporate users dependent on Intel apps find it difficult to plan their transition period. Furthermore, the limitation of advanced on-device Apple Intelligence models to M3 and later has led some users to question whether Apple is encouraging hardware upgrades. We will keep an eye on Apple’s explanation to see whether this feature restriction is merely a technical requirement or a strategic sales promotion.

Frequently Asked Questions
- Which Macs can run macOS 27 Golden Gate?
- Only Macs with Apple Silicon (M1 and later) are supported. All Intel Macs are excluded. Supported models include MacBook Air, MacBook Pro, Mac mini, Mac Studio, Mac Pro, MacBook Neo, and iMac with M1 or later.
- Will Intel Macs still receive security updates?
- Yes. Intel Macs running macOS 26 Tahoe will receive security patches and Safari updates for about two years after the release of macOS 27. For those on macOS 15 Sequoia, the period is one year shorter.
- Is Rosetta 2 still available on macOS 27?
- Yes, it is available for now. However, Apple has indicated plans to restrict Rosetta 2's functionality in future releases, and it is expected to be limited mainly to supporting older Intel-based games in the long run.
