Tip: Untick the Enable this account checkbox under your Apple ID, restart your Mac, and enable it again following the same steps to reset your FaceTime account. Sometimes, I unintentionally log in with an incorrect Apple ID or iCloud account, leading to difficulties initiating or receiving FaceTime calls. When you encounter problems with FaceTime, double-check that you have logged in with the correct account on your iPhone and Mac.
Fortunately, you can use quick troubleshooting techniques to resolve FaceTime not working on Mac problems. FaceTime is the undisputed favorite for video-calling friends, but issues like dropped calls, frozen screens, distorted audio, or unexpected app crashes can make it highly annoying.
