iMessages suddenly borked:- can't see network
Good morning, Experts.
2009 MacPro, (MacPro4,1) 12GB RAM, 4 x 1TB, 10.8.4
When opened, it logs into Jabber OK, but presents me with the login window for Accounts which shows iMessages for my Apple ID is inactive.
I try to log in and the little cogwheel goes round, then a dialogue box opens saying:-
Could not sign in to iMessage.
Could not sign in. Please check your network connection and try again.
This is when I'm on the 'net, using "Mail", logged into iCloud with the same AppleID, logged in on Apple Forums (all with the same AppleID).
I used Pacifist to extract and reinstall Messages from the Mountain Lion installer, but that installs 7.0 which won't run (missing library), so on to the next step.
I have downloaded the 10.8.4 Combo update and applied that, I have tried rebooting into safe mode, I have switched ID to my wife's account and tried logging in using her AppleID - all to no avail. I have tried logging in using my alternative "xxxxx@me.com" as applied.apple.com tells me - my regular email shows as verified on that page.
I have removed Little Snitch and MenuMeters just in case in some obscure way they were the cause - although they had happily co-existed with Messages since I'd updated to Mountain Lion a week after its release.
I have tried temporarily turning off the Firewall in System Prefs - that made no difference
Within Keychain (Keychain Access) there is an Apple ID Authentication for both my regular email address and my @me.com address. There are also two entries:-
"iMessage_temporary: xxxxx@btinternet.com" and "iMessage_temporary: xxxxx@me.com". both, when inspected, show my correct (if complex) password. Keychain repar reports no problems.
My iPhone 5 (iOS 6.1.4) is still happily using my AppleID for iMessage (regular email address)
Why would Messages suddenly, out of the blue, start being unable to realise there IS communication via the network?
I REALLY don't want to go through the Archive & Re-install Mountain Lion process - so I am seeking any assistance from all you experts.
Thanks in advance
Ted
