OS X El Capitan

Three weeks after releasing the first beta of OS X 10.11 El Capitan’s third major software update, and 48 hours after seeding iOS 9.2.1 beta 2 to developers and public beta testers, Apple on Wednesday released a second beta of OS X 10.11.3 El Capitan.

It can be installed on machines running a prior beta through the Mac App Store’s Updates tab and downloaded through Apple’s portal for members of the Apple Developer Program.

The pre-release software is also available to public beta testers who signed up for Apple’s Beta Software Program.

Today’s beta has a build number of 15D9c. The official changelog makes no mention of any new features or user-facing enhancements as Apple continues to focus on under-the-hood improvements.

The third major software update to OS X El Capitan should improve the stability, security and performance of your Mac while possibly adding some new features.

We’ll update this post with any changes as we encounter them.

    I hope this fixes the issue where Wi-Fi automatically turns ON after rebooting/starting up, it’s getting annoying, I’ll turn on Wi-Fi when I want not when the OS wants. Anyone else facing this on OS X 10.11.2 ?

      I don’t have this on 10.11.1, but normally when my wifi is off I’m connected to Ethernet.

      If the wifi is off and no other connections are present, it may turn it on automatically as default behavior.

      You might try System Preferences > Network > Wifi > Advanced and check “Require administrator authorization to – Turn wifi on or off”.
