Apple seeds fourth OS X 10.11.1 beta with potential Microsoft Office 2016 fix

Last updated

Apple on Wednesday released the fourth pre-release version of its upcoming OS X 10.11.1 maintenance update to developers and public beta testers, bringing with it the usual stability, compatibility and security enhancements.

The fourth beta seed, build 15B38b, comes one week after Apple issued the previous build to developers and member of its public beta program with minor bug patches and performance bumps.

In the accompanying release notes, Apple asks beta testers to focus on Mail and Microsoft Office 2016, the latter of which has encountered serious compatibility issues since the latest Mac operating system debuted. Office 2016 for Mac users have reported a wide range of issues since updating, including complete system freezes, that have yet to be solved.

OS X 10.11 El Capitan went live last month as a free update for Mac users, adding a number of new features like Split View, a revamped Notes app, various user interface tweaks and multiple backend enhancements.

Developers and public beta testers can download the latest El Capitan build from the Mac App Store or Apple's developer website.
