Rumors suggest that macOS 26 will drop support for older Intel-based Mac models including the MacBook Pro (2018), iMac Pro (2017), Mac mini (2018), and MacBook Air (2020, Intel-based).
Apple is expected to narrow support for Intel-based Macs in macOS 26, continuing to focus on delivering full features primarily to Apple Silicon devices.
The compatibility list for macOS 26 is anticipated to include newer models like MacBook Pro (2019 and later), iMac (2020 and later), Mac Pro (2019 and later), and more.
macOS 26's first developer beta is expected to feature significant design changes inspired by visionOS, and it will likely be officially announced at Apple's WWDC in June.
