FaceTime failure
QI have a new 12-inch MacBook (Early 2016). Although I’ve entered my username and password in order to make calls using FaceTime, the app gets stuck on its loading screen and does not work. What am I doing wrong?
AEnsure you have a good internet connection, and that the Apple ID you’re attempting to sign in with is valid. To make a FaceTime connection, you must have verified your email address; check your Apple ID’s status by going to appleid. apple.com, where you can also create an Apple ID, change its password, and more.
Next, in FaceTime choose FaceTime > Preferences. If it shows your email status as ‘verifying’, follow the instructions in the email to verify the address, and allow the process to complete. If FaceTime is still being awkward, under Apple ID in the app‘s preferences, clear and refill the ‘Enable this account’ checkbox.
Other factors that can cause problems with FaceTime include not having the correct time, date, and time zone set, and trying to connect through a firewall that blocks ports. FaceTime needs ports numbers 80 (TCP), 443 (TCP), 3478-3497 (UDP), 5223 (TCP), 16384 to 16387 (UDP), and 16393 to 16402 (UDP).
You may need to use your router’s admin tools to verify those ports aren’t being blocked for outgoing connections; also check security software on your Mac isn’t interfering. Apple provides further ideas at apple.co/2eGdRYZ.
