Users shouldn't have to worry about unattended OS downloads like this one happening without their permission or awareness.
Or, you know, just use skype on your phone
The real question is, why did it only try to update and download Sierra then?
This is one of the reasons I don't leave any downloads to automatic.
During the Skype call I had shitty QOS too, and yes, the full download had completed by the time I'd finished the meeting, because the MacBook was closed immediately after.
I will turn off automatic download now, obviously, but I honestly believe that a OS upgrade isn't acceptable as a background download.
Simply because it's not an automatically applied update.
Yeah, I totally agree. You might not even want it
On reflection, I don't think I'm actually gaining that much (or anything at all) by letting them run automatically anyway. It's a false convenience.
A computer without a network bandwidth display is like a car without a speedometer. I wish all OSes had this, would cut down on people's mystery wifi complaints.
Part of the reason might be that software engineers at companies like Microsoft and Google have unlimited data as a perk with their employees' personal cell phones (even still on Verizon today when a regular Joe cannot even get unlimited data anymore).
After leaving BigCo, I never upgraded my phone again because of the perk.
