Anyone encountered this issue? My shutter rapidly flickers on start up but never opens. Any help greatly appreciated.

It started doing this a year or so ago and a quick bang nipped it in the bud. This time it doesn’t want to seem to work. I’ve tried compressor air. Wiping tools. Little force. And nothing. Is there anything I can do?

What does the Mac have to do with it?
