What this page covers
This guide explains the real reasons a Mac cannot login to FaceTime, the steps you can try yourself, and when it’s time to get professional on‑site help. It applies to:
• FaceTime on macOS
• Apple Account sign‑in
• iMessage and FaceTime activation
• iCloud syncing for calls
If your Mac refuses to sign in to FaceTime, keeps asking for your password, shows “An error occurred during activation”, or won’t make or receive calls, this page is for you.
The most common reasons a Mac cannot login to FaceTime
These are the issues that Keith Thomas identifies most often during on‑site visits:
• Incorrect Apple Account password

• iCloud Keychain conflicts
• macOS update issues

Quick checks you can do yourself
