Apple releases fourth public beta of OS X 10.11 El Capitan

Apple on Tuesday provided public OS X beta testers with the fourth pre-release build of El Capitan, its forthcoming free Mac operating system update set to launch this fall.




The new public beta of OS X 10.11 comes one day after the sixth developer beta was released. It is likely that both builds are identical.

The latest build is said to include only minor tweaks and bug fixes from previous versions. Betas of El Capitan have been released more quickly, suggesting that Apple could be nearly done with the OS X update and is only working on polishing code before a public debut.

Still, beta releases are known to feature bugs, as one tester told AppleInsider on Tuesday that they have experienced a kernel panic with the OS X Mail app in the latest version of El Capitan. As such, testers are advised to not install El Capitan on their Mac's main partition.

OS X 10.11 El Capitan is somewhat of a polish of last year's OS X 10.10 Yosemite update, refining things that were previously introduced. However, there are a handful of new features in the next-generation Mac update, including Split View, a better Mission Control, and various performance improvements such as Metal graphics processing.
