iMessage (inactive). cannot sign in since yesterday

I just upgraded to Mountain Lion here today and I can't signin to iMessages either, works fine on my iPhone & iPad just not on the Mac Mini.

I fixed my problem, I had setup a custom hosts file way back, in there was something blocking versign.com remarked everything out and saved the file and tried iMessages and logged in right away, so check your /ect/hosts file.

+1 on Islander's comments. No idea where the hosts file entries re versign.com came from, but removal has resolved my iMessage problem and it connected stratight away.

Thanks!

Finally. This one solved it for me.

I do remember why I had hosts file changed, but of course, forgotten I had done it.

Thanks!

Do you mind giving me a bit more details what to do exactly inside etc/hosts ... thx

Basically it should be in it's most basic state.

This is what worked for me:

- Go to Preferences in Messages

- Sign in with your Apple ID (if you already haven't)

- Click on the Details button

- Enter the Apple ID password and click "View Account"

- Add a country to the location in the bottom left of the window because that's blank!

- Save

- Restart iMessage

- and boom!

🙂

HI,

Thanks for that.

I had presumed that they had done away with the Country setting in version 7.0 when Messages was updated to version 7.0.1

I notice the new spot that I was unaware of has a Email tick box that some people may want to untick.
