I've been using my 11" MBA (Early 2014) for a bit over a month now; totally satisfied, but one thing continues to puzzle: I have all App Store options pertaining to auto-download and update presently checked; It doesn't appear that any update I've ever had take place in the last thirty days occurred automatically. Right now, Safari 8.0.2 is staring back at me in the App Store, apparently waiting for me to click "update." Going into the System Preferences for App Store, the button tells me that there are updates available, and allows me to show them, but still, after about fifteen minutes it doesn't feel compelled to do anything about it. Is there a reason this might not be occurring? Will a Safari update simply not download automatically?
