Apple on Tuesday seeded the fourth beta of OS X 10.11 El Capitan to developers. The new release comes two weeks following the release of the third beta seed.
The update, build 15A226f, is available via the “Update” tab in the Mac App Store, or via download from the Apple Developer Center. Apple also released Xcode 7 beta 4, build 7A165t.
At this point in time, we don’t know what new features, if any, the new beta seed brings to the table, but we will update this post as we discover what’s new.
Issues do remain in El Capitan with Photos, Apple ID, and Language. Apple also warns developers to NOT upgrade to OS X El Capitan from OS X Lion or earlier to OS X El Capitan.
The release of El Capitan is intended as a refinement of OS X Yosemite, although it also offers new features, including Split View, a tweaked Mission Control, and improved built-in apps.
