Hi there, Something weird has been going on with my Thunderbolt Display since a few days. How I'm using my Macbook: When I'm at home I have my Macbook Pro connected to my thunderbolt display, and this setup sometimes does not change for a few days. The lit of my Macbook is closed. So previously (the last 2 years or so) I would just tap any key and the display would turn on. just like you would expect. Now since a few days, this does not happen at all. It just stays black. Another indicator is that my Bose 2.1 speakers, the controller, shows a red light (what means; nothing connected) To get it working, I have to open the lit, unplug the thunderbolt cable, plug it back in. And the TB display wakes up. Anyone has any idea? as this it getting pretty annoying.
