An unexpected error occurred on Mac Operating System
I am using Mac Operating System X 10.6.5 and get an error message every time I tried to update my Bluetooth. I have spent many hours to fix this problem but I am unable to resolve this issue. Is there any way to update it properly? Please suggest a proper solution step by step. I would be grateful to you. Thanks.
