2010 MacPro giving high pitched sound and red flashing light
Recently (and frequently), my 2010 Mac Pro has been giving me a high pitched sound as well as a red flashing light through the front mesh when I try and start it up.
Some times it takes a few tries to actually get it to turn on.
I did a Disc Utility check and it says that all my drives are okay?
I also ran AppleJack last week and had the noise and light today.
Mac Pro, Mac OS X (10.7.3)
