Q: Download of 10.12 Developer Preview fails.
Download of macOS 10.12 Developer Preview from the App Store fails to complete with the error, _An error has occurred_, in red letters. Signing out and signing back in changes nothing. Quitting and relaunching App Store changes nothing.
HOWEVER, booting into Recovery shows macOS 10.12 as available for re-install! But, if I try to "re-install," the time remaining on the "re-install" counts down to ... 3, 2, 1, 0, -1, -2, -3, -4, -5 ... till the time runs into negative minutes and I get tired of waiting and re-boot into El Capitan 10.11.6 Beta 3.
