beep and internet connection
I have a black MacBook that is 8 months old. Just last week it started beeping. The first two days quite frequently but not regularly. I also thought it was connected to my internet connection because the beeping started after I rewired my modem. To test, I simply disconnected my MacBook (i.e., just pulled out the aether cable) and that worked!
But now, of course, it still beeps every once and a while. And I don't understand why. Could it not be connected to something relating to the internet connection, like a firewall?
