Following today’s WWDC 2024 announcements, Apple has released the first Developer Beta for macOS 15 Sequoia. You can test the latest system on any compatible Mac, given you have a developer account.
This version requires a supported Mac. MacBook Airs from 2020 onwards, iMac Pros, and all other Macs announced since 2018 are compatible with macOS 15 Sequoia.

Downloading macOS Developer Betas
If you have an Apple Developer account, the update should appear to you in System Settings > General > Software Update. You can use your regular Apple ID to create a free account on the Apple Developer site.
Expect the Developer Beta, as an early test build, to be unstable. If you’d rather wait for a more polished release, macOS 15 Sequoia Public Beta will be announced next month. The final version becomes available this Fall.
