Apple has officially announced that no Intel-based Macs will receive support for macOS 27. The move marks the final step in its transition to Apple silicon chips, affecting specific older models. The decision impacts users and developers relying on these devices.
Apple has confirmed it will not support any Intel-based Macs for the upcoming macOS 27, marking the end of its transition from Intel chips to Apple silicon across all Mac models. This decision affects several older devices and signifies a shift in the company’s hardware and software strategy.
During the WWDC keynote, Apple announced that macOS 27 Golden Gate will only be available on Macs powered by Apple silicon processors, such as the M1, M2, and newer chips. The following Intel-based models will not receive the update: MacBook Pro (16-inch, 2019), MacBook Pro (13-inch, 2020 with four Thunderbolt ports), iMac (Retina 5K, 27-inch, 2020), and Mac Pro (2019). The 2020 MacBook Pro with two Thunderbolt ports was already dropped from support last year, but the variant with four ports was supported for macOS 26 Tahoe. Now, both are excluded from macOS 27 support.
This marks the completion of Apple’s transition, which began in 2020 when the company announced plans to shift from Intel to its own chips across all Macs. Over the following years, Apple replaced all Intel-based Macs with Apple silicon models, and support for the older hardware has been gradually phased out.
Implications for Mac Users and Developers
This decision impacts users of older Intel Macs who will no longer receive software updates, potentially affecting security, compatibility, and performance. Developers targeting macOS 27 will need to focus on Apple silicon, which could influence app development and ecosystem support. The move underscores Apple’s commitment to its own chips and signals a clear hardware-software integration strategy.

Apple’s Transition from Intel to Apple Silicon
Apple announced in 2020 that it would transition all Macs from Intel processors to its own Apple silicon chips. Over the next two years, the company replaced all Intel Macs with models powered by its M-series chips. Support for Intel Macs was gradually reduced, with some models already dropped from software updates. The announcement at WWDC 2026 confirms that the transition is now complete, with no future support for Intel-based Macs in macOS 27.
“Apple’s decision to drop support for Intel Macs signifies a full shift to its own silicon, emphasizing tighter hardware-software integration.”

Key Questions
Will my Intel Mac continue to receive security updates?
It is not yet confirmed whether security updates will continue for Intel Macs after support ends with macOS 27. Apple typically provides security patches for a limited time after support ends, but users should plan to upgrade hardware.
Which Mac models are affected by this support cutoff?
The affected models include the MacBook Pro (16-inch, 2019), MacBook Pro (13-inch, 2020 with four Thunderbolt ports), iMac (Retina 5K, 27-inch, 2020), and Mac Pro (2019). The 2020 MacBook Pro with two Thunderbolt ports was already unsupported for macOS 27.
Will Apple continue to support older Apple silicon Macs?
Yes, all Macs powered by Apple silicon, including recent models like the M1 and M2, will receive support for macOS 27 and subsequent updates.
What does this mean for software developers?
Developers will need to focus on optimizing their applications for Apple silicon, as support for Intel-based Macs will be discontinued. This may involve updating codebases and testing on newer hardware.
