Apple Releases Mac OS X 10.11.3 El Capitan Beta

Apple Releases Mac OS X 10.11.3 El Capitan Beta

Yesterday, Apple released Mac OS X 10.11.3 El Capitan Beta to developers. I’m sure that those on the public beta program got it as well. If not, it should be available by now.

Mac OS X 10.11.3 El Capitan Beta came alongside iOS 9.2.1 Beta yesterday, which they didn’t publish release notes for, oddly enough. As you can see from the release notes below for Mac OS X 10.11.3 El Capitan Beta, they don’t really say anything.

My guess is that Mac OS X 10.11.3 El Capitan is really a bug fix update, much like iOS 9.2.1 is. You just don’t see a lot of bug fix version numbers for Mac OS. Version numbers go major.minor.bug fix, so iOS 9 is major, iOS 9.2 is minor, and iOS 9.2.1 is bug fix.

Mac OS X works differently though, as the 10 is just part of the OS name and never changes. Because of this, Mac OS is 10.major.minor, and you rarely see a bug fix number, such as 10.11.2.1. Nevertheless, I’ll keep you updated if there are any front facing features.

OS X El Capitan 10.11.3 build 15D9c Seed Notes

 

The OS X El Capitan 10.11.3 update improves the stability, compatibility, and security of your Mac.

 

Installation Instructions

Please be aware that you will not be able to revert back to your previous system after updating. Please install this update on a system you are prepared to erase if necessary.

 

You can install this update using the OS X Software Update Seed Configuration Utility:

 

  • If you have already installed the new “OS X Software Update Seed Configuration Utility”, choose “Software Update” from the Apple menu. Otherwise, proceed with the following steps.

  • Log into your Apple Developer account and download the “OS X Software Update Seed Configuration Utility”.

  • After running the installer, the Mac App Store will open automatically. Click on the Updates panel and the latest version of OS X seed will now be available for download.

  • When a newer seed build is available, you will receive a notification to update from the Mac App Store. Click the notification to begin the installation. New seed notes will be posted in the Mac Dev Center.

  • To stop receiving new seed builds, go to the App Store in System Preferences and where it says “Your computer is set to receive pre-release Software Update seeds”, click on the “Change…” button.

 

Note: If you are using a computer which gets its updates from a local Software Update server, the OS X Software Update Seed Configuration Utility will reconfigure your machine to use Apple’s Software Update servers. Your computer must be able to connect to Apple’s Software Update servers to install the seed. We recommend that you remove any Configuration Profile that specifies a local Software Update server before installing the OS X Software Update Seed Configuration Utility.
