Apple releases first OS X 10.11.1 beta to developers, new emoji included


After seeding developers with the OS X 10.11 El Capitan GM last week, Apple is now providing developers with the first build of OS X 10.11.1 beta for testing. The version features build number 15B17c compared to OS X 10.11 GM’s 15A282a.

Registered developers can find the OS update in the Developer Center. Updating from a previous OS X version requires downloading the OS X Software Update Seed Configuration Utility, then checking for the update in the Mac App Store’s Updates section. The update measures in at 606 MB. We’ll dig into the latest beta and report any notable differences between it and the OS X 10.11 GM.

    In the release notes of this update, Apple should have just put the middle finger emoji. That would’ve been awesome!

      LOL. I used Res Edit to modify the error message on my old Mac OS computer. i did to a friend’s system as a joke behind his back, so every time an error message came up it flipped him off, and I changed the text to include his name and say all kinds of nasty things. It was funny. Ya had to be there. God I miss Res Edit. That was fun!! Or how about Kaleidoscope? Anyone remember that little gem and waste of time? It was fun, but certainly not a productively tool.

    Geez, I hope that doesn’t imply the current GM seed available on the dev site is the one going out. So many people reporting upgrade problems on the forum, literally trashing installations. I tried installing it fresh to a VM and it hung and wouldn’t even finish. I’m not too encouraged right now.
