I looked up today and noticed that my bluetooth logo had a jagged line through it. I clicked on it and it says bluetooth not available, then I went to system preferences and, now there is no bluetooth icon to click on. I opened spotlight and found bluetooth, but then I got an error saying that no bluetooth hardware was detected. I have the MBP in my sig. Also see attached screenshot. Anyone ever encountered this? My MBP is still under warranty for 3-4 more months. Should I just take it to an Apple store?
