Apple on Tuesday seeded the fourth beta of OS X 10.11.5 to developers and public beta testers for testing. The new beta comes just one week following the third beta release of OS X 10.11.5.
The new beta – Build 15F31a – is available via the “Update” tab in the Mac App Store, or for download via the Apple Developer Center.
It isn’t know at this point in time what new features, if any, the new beta brings to the table. It likely focuses on security enhancements, performance improvements, and bug fixes to address issues that have been discovered since the release of OS X 10.11.4. We will post anything we find out about the new beta right here, so stay tuned.
