Well, I don't know how to describe this phenomenon, but when you get a normal notification on the top right hand corner, you can just swipe it away and move on with your day. But with OS X Update notifications, it just comes back a few minutes later. Now, I can ignore it, but unfortunately it obscures some of the windows that I'm using when I need to hit a button near that area. This is so annoying, and apparently there's no way to stop OS X from notifying me on the Notification Center Preferences. Obviously the solution is to update OS X and move on with life right? But what if an update is reported with bugs, or what if in the future it removes something I may rely on? Why can't I swipe this away for good?
