mac keeps typing ;;; continuously

I have noticed similar behavior on machines when two keyboards are being used. In my case, I found the cause was something physically hitting the keys of the keyboard. I would check whether or not this type of issue is in play within your environment. To test, turn off the bluetooth keyboard by removing the battery or placing it in another room. You may also want to check if you have an older bluetooth keyboard around that might be causing interference and take steps to isolate the bluetooth signals from the Mac.

Hi there,

I've had this issue for the past couple of months where randomly my MacBook Pro will start typing a series of ;;;;;;;;;;;;;; continuously and non-stop. This happens both when typing directly with the laptop keyboard and when typing through a bluetooth connected keyboard. It also seems to randomly start and stop. Re-starting the computer does not resolve the issue. Does anybody else have this problem? If so, how did you fix it?

Thanks!

Sounds like a hardware issue—

you do not say what exact Mac is this...?
