MacBook Pro making Dial up sounds

Hi jeztrac,

Thank you for participating in the Apple Support Communities. We understand your Mac is making sounds similar to a modem, and we'd like to help. What applications are open when this occurs? You may want to test to see if the issue occurs when you boot in safe mode? This can help us know if the issue is caused by a third party application. Here's how:

Start up your Mac in safe mode

To help rule out any hardware issues, you may want to run Apple Diagnostics as well.

Use Apple Diagnostics to test your Mac

Take care.

Why is my Mac making sounds like a modem? It’s quite soft and stopped when I turned off wifi on my Mac

Do you find it comforting or disturbing...(?)
