I have a 2010 Mac Mini it runs fine most times but it has been getting really sluggish & jerky lately. I have a magic trackpad and a apple bluetooth keyboard and both get sluggish at the same time. I have 8gb's of ram and fixed permissions but the issue remains. Only way to fix it is to reboot, as u can imagine rebooting several times a day is frustrating. I ask if its a bluetooth issue b/c when I use my bluetooth headset after maybe 45mins sometimes less the system gets sluggish and the sound in the headset gets distorted. Thats 3 bluetooth devices that are experiencing issues. Is there a way to update the bluetooth software or does that come from apple exclusively?
