Apple has removed the MacOS Sierra GM . . .
Indeed! The 16A323 installer has disappeared from my "Purchased" tab in the App Store app as well.
Don't you just love it when Apple does things on your machine without letting you know about it? . . . well, not exactly on your machine, but you know what I mean.
Update: Interesting. If you use the command line version of MAS and use the list command, Sierra is not listing there with its identifier either, as it did before.
In fact, I have been wondering lately if Apple has some of its employees check forums and threads like this one, and then finds and implements ways to frustrate our methods of getting builds for supported and unsupported machines other than through official channels. It seems to make sense that they would do something like that.
Are we in fact shooting ourselves in the foot by so publicly discussing these things?
BTW, it is currently Wednesday, September 21st, 2:21 AM here.
