10 Fixes for "FaceTime Not Working on Mac after Tahoe Update"

Why Is FaceTime Not Working on Mac (Tahoe)?

Before listing the causes, let’s understand how FaceTime works. To use it, your Mac needs to run macOS Lion 10.7 or later. You’ll also need a stable Wi-Fi, cellular data, or broadband internet connection. Finally, you must sign in with a valid Apple ID and use functioning microphones and speakers, either built-in or external.

With these requirements in mind, FaceTime may not work on Mac due to:

  • An unstable or weak internet connection.
  • Running an outdated macOS version (earlier than macOS Lion 10.7).
  • FaceTime being turned off, possibly disabled manually.
  • Using an incorrect Apple ID, preventing contact with desired users.
  • Incorrectly set date and time, which may not match the FaceTime server.

10 Ways to Fix FaceTime Not Working on Mac (Tahoe)

Now that we understand the causes, here are 10 practical fixes:

1. Restart FaceTime

Like other software, restarting can resolve temporary glitches. Quit FaceTime by clicking its icon in the dock and selecting Quit, then reopen it to see if the issue is resolved.
