Apple has released the fourth beta of OS X 10.11.1 to both developers and public beta testers as part of its Beta Software Program. Both developers and public beta testers can now grab the update from the Mac App Store if they have a previous beta version installed, while developers can also head to the Mac Developer Resource Center to grab the latest build.

OS X 10.11.1 will be the first major revision to the OS after its public release, but aside from some new emoji, it isn't immediately clear what fixes or improvements the update contains.
