How to disable mouse in vim window when it's enabled by "set mouse = a"?

Question

Hi: I'm using vim and I've set mouse=a in my .vimrc, so upon startup, vim supports mouse cursor. But some times I need to copy text from terminal, so I need to shut down mouse support in vim. I tried set mouse=c but the mouse still works in my mac terminal.

Is there a way to do this? Thanks!

Try

:set mouse-=a

The -= removes any active option.
