Apple Seeds macOS High Sierra Developer Beta 9 Build (17A360a)

Apple seeded macOS High Sierra developer beta 9 on Monday, dubbed macOS High Sierra 10.13 beta 9 (17A360a). Apple is using each release to squash bugs, tweak the interface, and try different approaches in new features.

Registered developers can find the update at the Apple Developer Connection. Devices that have already been provisioned for the developer beta cycle can find the update in Software Update in the Mac App Store.

Friday’s release accelerates an already accelerated release cycle, as the last round of developer betas hit just four days ago. Apple is expected to ship macOS High Sierra in September or October.

This release does not affect those who are running the public beta of macOS High Sierra.
