I'm trying to download the latest version of El Capitan (10.11.4) to build an updated flash drive installer. I fire up the App Store, click the OS X El Capitan link on the right, then click the Download button. A pop-up warning asking:
Would you like to continue? OS X v10.11.4 is already installed on this computer. Use the Updates page to install the 10.11 update or if you would like to download the full OS X installer click Continue.
Since this is indeed what I'd like to do, I click the Continue button. The pop-up goes away and the spinner in the upper left keeps going. Eventually, I get tired waiting for the spinner to stop, so I'll go to a different desktop and do stuff or minimize the App Store window. When I return to it, the spinner is gone, nothing is downloaded, and I can no longer click the Download button. (The text appears slightly less dark.)
I can exit the App Store, restart it, go back to the El Capitan page and do the whole process again, but nothing seems to let me download the full, latest version of 10.11. Even if I use defaults to enable the debug menu on the App Store, bump the logging level up to 4, there's not a lot of info shown in Console.
Restart didn't change behavior. Disabling the Little Snitch network filter didn't affect anything.
Any suggestions for how I can d/l this version to build an updated install drive?
