Disable phone call notifications on my iMac

I do not need to download anything. I want to turn off a function that I never agreed to have on in the first place. I do not want my iPhone notifications coming through on my iMac.

I have the same issue. I followed the instructions to disable through FaceTime last night, and today I'm still receiving notifications and text messages on my iMac. This is a terribly intrusive feature when trying to sync audio to video footage. Please help me turn this off!
