Apple has officially seeded the third developer beta of OS X 10.11.5 for testing purposes.
Apple has seeded the third beta of OS X 10.11.5 to developers, build 15F28b. This release arrives just under three weeks after Apple seeded the first developer beta to developers. It has been just under a week since Apple seeded beta 2 to developers.
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.
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.
