I cannot log into iMessages on my MacBook Pro. Works fine on other devices.

Hey again!

My best guess would be an issue with the local keychain.

If you create and log into a new admin user and it works fine that may be the case.

I would quit all open apps, ensure you have your Apple ID password then:

Open Keychain Access from Finder > Applications > Utilities.

In the search bar on the top right, search for each term individually and delete any entries or results in the Keychain, restart and test:

Terms:

ids

iMessage

Facetime

Appleid

Hope that helps! If not it could be something else such as a permissions issue, knowing if it works in another user account will help to identify if the problem is system wide, or confined to a particular user account, thanks.

The VPN could be blocking your iMessage.

Make sure both your AppleID email address that is registered when you login Apple Support Communities and your phone number is in Messages menu -> Preferences -> iMessage, and that you are signed in the AppleID there.

Hey candacevanlion!

Can you please say what happens when you try to log in? It there are any particular error messages? And/Or if it has ever worked on this Mac, and if so, if any type of changes were made from when working to not working?

Cheers, glad to help out of I can. More info may help though.

Why did you pick the VPN article? Do you have one?

Hey Candacevanlion!

Awesome, good to hear, glad I could help out!

Glad to hear it.
