Apple has just seeded the third beta of OS X 10.11.5 El Capitan to developers and public beta testers, one week after releasing the second OS X 10.11.5 beta and a month after releasing OS X 10.11.4, the fourth update to the OS X El Capitan operating system. OS X 10.11.5 has been in testing since April 6.
As far as what’s new, the beta release appears to be a minor update, with performance enhancements and bug fixes. However, if something new is discovered within the software, we’ll be sure to update this post accordingly.
The new beta software can be downloaded from the Apple Developer Center. It is also available as an update through the Mac App Store and the Update tab for machines running the first beta.
