When the cutting noise happens when connecting to the Mac via bluetooth, you maybe able to solve it with clearing the PRAM memory.
Resetting the PRAM
You reset the PRAM / NVRAM by doing the following:
- Reboot a Mac and then immediately hold down the Command+Option+P+R keys
You will then hear the Mac reboot sound again, signifying that the Macs PRAM or NVRAM has been reset successfully.
