On a Mac, how do I interupt VBA code that is running?

I am running a Mac (not a Windows PC). When VBA is running an infinite loop, how do I interrupt it? Ctrl Break works on a Windows PC, but there is no "Break" key on my Mac.

Thank you in advance!

Try,

command + .

Try holding the Esc key down for several seconds.

This works as well when held down for several seconds.
