My dad as the most recent Mac mini. He got the 10.8.3 update. After the update he noticed that his Trackpad was not working normally. He went into the System Prefences, clicked on Trackpad and it says he has no trackpad. He then went under Mouse and it shows that he has a mouse, which is incorrect. He is using a trackpad. He tried to go to Bluetooth in the menu bar, and it has a line through it. After clicking it, it shows "Bluetooth: Not Avaiable." In addition, Bluetooth has disappeared from System Prefrences. My dad has reset the computer multiple times, reset the SMC and also the PRAM. Still no luck.
