Remember OS X? macOS Sierra is the new hotness, but OS X El Capitan has at least one more update left before the big name change takes place later this year. OS X 10.11.6 isn’t quit ready for prime time yet, but Apple has released the third beta version of the Mac software update for testing.

Apple first started testing the Mac update back in May. The last beta version was released earlier this month with updates two weeks apart. The update is generally without new features and likely focuses on security improvements and bug fixes.
