Ive noticed that every time i wake from sleep or restart or shut off then turn on my MacBook Pro (Retina, Mid 2012) that not only do all my notifications disappear, but all my settings also get shut off. In safari > preferences > notifications it shows that everything is as it should be. If i go through and "re-allow" the websites to push notifications, i get a few "missed" notifications and start to receive them again until i sleep, restart, shutdown then turn on my rMBP. Anybody else noticing this? it was really nice in mavericks.
