2009 mac compromised

What do you mean by "compromised"? If you suspect malware you can run Malwarebytes. Malwarebytes was developed by one of our own colleagues here in ASC and is about the most proven anti-malware software for Mac. It’s the only one recommended by Apple tech support folks.

It's a known scam. No one is watching you, it's not possible to access your camera or any part of your Mac remotely. Ignore it and move on.

Yeah it's a pure scam.

Why would you do that?

It has not been compromised.

The message you got is a scam. Ignore it and move on.

No. They didn't.

We're pretty certain he's correct.

I've gotten the same message, but not only does my Mac Pro not have a Camera, but I have no Phone... I'm deaf!
