I have trouble after 3 hours the mouse and bluetooth stop
iMac 21.5" Mid 2011 2.5 GHz Intel Core i5
I'm having trouble with my 21.5" iMac. After working for 2 - 3 hours the mouse with Bluetooth and USB port connected keyboard stop working.
Sometimes I can work a whole day without any problems, other times it stops and I have to restart my system to get it working again.
How can fix this? Thanks
I have this error: 4SNS/1/40000000: TH00-9.000
Ist dies eine gute Frage?
Have you tried running any diagnostics? How about rebooting your system and holding the 'Option' & 'D' keys to let the builtin diagnostics run
Reference: Startup key combinations for Mac

Can you please help, I have this model and my Bluetooth and key board is not responding.
