error -7034 iMessage on mac

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

The title of the Console window should be All Messages. If it isn't, select

SYSTEM LOG QUERIES ▹ All Messages

from the log list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar at the top of the screen.

Click the Clear Display icon in the toolbar. Then take an action that isn't working the way you expect. Select any lines that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.

The log contains a vast amount of information, almost all of which is irrelevant to solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.

Please don't indiscriminately dump thousands of lines from the log into this discussion.

Please don't post screenshots of log messages—post the text.

Some private information, such as your name or email address, may appear in the log. Anonymize before posting.

When you post the log extract, you might see an error message on the web page: "You have included content in your post that is not permitted," or "The message contains invalid characters." That's a bug in the forum software. Please post the text on Pastebin, then post a link here to the page you created.

Having the same issue as of today. I hope somebody can figure out a solution to this. Its getting quiet frustrating.

solution: delete iCloud from Mac preferences. It will ask to rid of all your iCloud connectivity in Mac. After that you'll be prompted to add a new iCloud account, sign back in and verify your account and you should see iMessage functioning again. It will take a moment however to update so be patient.

I too am getting this issue for a couple of weeks now.
I've even gone as far as installing a fresh copy of Yosemite on a clean hard drive as a test.

All iCloud apps work fine except for messages.

I got a log dump when I tried to log on

I hope this is the correct event.. This pooped up as soon as I tried to log into messages

Hello,

Try resetting the pram and when you're finally back in, delete icloud preferences, the restart, reconnect to icloud after restart and thats what worked for me. I dont know if it was luck but worth a try. Hope it works out for you!

I've already deleted all icloud, imessage and all com.apple.ids.service.com.apple.xxxxx prefs files, but I'll try the pram thing.

As I mentioned though, I have even created a clean OS installed on a fresh drive and booted from that.

I'm 99% sure the problem exists at the apple server end.... but that's like trying to convince ppl 9/11 was an inside job... No one believes you no matter how much evidence you provide.

Typical "Microsoft" type reply from tech support... "Have you tried rebooting?"

Well well... resetting the PRAM actually worked.

for the first time in 2+ weeks my imessages is actually working again

Thanks

I was having this issue as well. This is what I did to resolve it:

1) Navigate to ~/Library/Preferences and deleted anything that started with com.apple

2) Deleted MobileMeAccounts.plist

3) Delete loginwindow.plist

(Obviously deleting all of it wasn't necessary, but remember - these files are preferences. They can be reconfigured. If you know what some of them do, you can leave them, but I was fed up with troubleshooting this problem. I don't know exactly what each one does or how it was tied to the logs showing in console, so I just got aggressive.)

4) Restart and reset PRAM.

It worked.
