What Macs will be able to run macOS Tahoe
It's nearing the end of an era for Apple, as the upcoming macOS 26 "Tahoe" will be dropping support for all but the last Intel-based Macs.

macOS Tahoe will drop support for several Mac models.
On Monday, Apple unveiled macOS Tahoe with a slew of new features, including an interface redesign, significant updates to Spotlight, and additional Continuity experiences with Live Activities and the Phone app. However, not all Macs in the wild will get access to macOS 26.
According to Apple, macOS Tahoe will be compatible with the following devices:
- MacBook Air with Apple Silicon (2020 and later)
- MacBook Pro with Apple Silicon (2020 and later)
- MacBook Pro with Intel chip, 16-inch (2019)
- MacBook Air with Intel chip, 13-inch (2020)
- iMac (2020 and later)
- Mac mini (2020 and later)
- Mac Studio (2020 and later)
- Mac Pro (2019 and later)
As previously rumored, the new version of macOS drops support for 2018 MacBook Pro models, 2019 iMacs, and the iMac Pro.
The surviving Intel-based Mac models all appear to have at least the T2 security chip. However, macOS Tahoe also dropped support for a few T2-equipped models, such as the 2018 15-inch MacBook Pro.
This may prove problematic for for the OpenCore project, allowing modern operating systems to run on older, unsupported Macs. It's not clear how they'll perform the data harvesting going forward.
They're industrious, however, and we'll be keeping an eye on their project.
Apple has released the first beta version of macOS Tahoe to developers for testing on Monday. Members of Apple's Public Beta Program will be able to test drive the update in the summer.
AppleInsider, and Apple itself, strongly recommend users don't install the betas on primary devices or hardware they deem as "mission-critical" at all, as there is the highly remote possibility of data loss or other issues. Testers should instead install betas onto secondary or non-essential devices as a safer alternative, and to always make sure there are sufficient backups of important data before updating.
