Messages.app/Facetime Broken/Not-Working in Yosemite 10.10

Thought I might have found a solution. In System Preferences>Internet Accounts, Messages is listed and requested a log in under my gmail account ...it was happily accepted my password. However, when I tried to log into the Messages app, it failed. I got an email from Google stating that they had blocked a sign-in attempt, with the comment "Whoever tried to sign in to your account knows your password; we recommend that you change it right away."

I sounds like it recognizes the password, but will not let me in. I have enabled access from "less secure apps" ....to no avail.

Giving up ....will disable the "less secure apps" and wait for something from Apple.

Good night, Ralph

I'm having a nearly identical problem. I'm currently working with a Senior TS rep and Apple Engineers to resolve. If I find the resolution, I'll let you know.

Howdy. I have a mid-2010 MacPro with EXACTLY the same problem as you with iMessaging and FaceTime. Both worked perfectly in Mavericks. I have tried the complete troubleshooting guide provided by others, which was pretty significant, and no change resulted. I also have a MacAir (2012) and it all works perfectly on that machine with Yosemite. I am using a Samsung SSD EVO with a few workarounds to get Trim to work in Yosemite. Anyway, thinking that might be a problem, I got a 1T HDD, formatted it and did a completely clean install of Yosemite. I then removed the SSD, but in the HDD and tried all over again. ABSOLUTELY NO CHANGE with iMessage, but I don't seem to be prompted to login to FaceTime overtime I start up, with the clean install. There are some other strange glitches, but those are for another thread. However, I will need to start something about iCloud Drive. Why can't they just get this thing right from the start? It is not as though they don't have some good examples out there to copy (e.g. DropBox and Box).

See if following these directions will help... perhaps the IMagent has become disabled?

IMAgent is an OSX daemon which runs as part of FaceTime. You can disable it with the following command:

launchctl unload -w /System/Library/LaunchAgents/com.apple.imagent.plist

You can re-enable it with the following:

launchctl load -w /System/Library/LaunchAgents/com.apple.imagent.plist

You can test to see if it’s running with the following command:

sudo launchctl list | grep imagent

Understood.

On the one hand it does seem the end user is getting caught between Apple and Google and who thinks what is secure.

On the other there are not that many reporting the issue.

The Blocking of a sign in attempt should at least get a message "Was it you ? You might need to do this" rather than give you no way to rectify it.

For another thread I launched my older version of an app called Psi (a Jabber app effectively).

I have it set up for two Jabber Logins one of which is Google.

I don't have Two Step verification (never set it up in the first place) and do have Less Secure App enabled.

This app also managed to Login

Messages is using port 443 (and SSL) and the Psi app is using the 5223 port with SSL

It reports the Certificate is Self Signed with a "Connect anyway" option button.

This does suggest something about this works and that Google will allow some lesser secure logins if we believe everything they tell us.

I see that there other posts in this thread that I need to read.

Hi,

Simple method.

Open Activity Monitor in Applications/Utilities

Find imagent (lower case and with no icon) in the list

Highlight and use Quit icon top left.

Confirm Quit.

It will restart and appear at the top of the List.

Deleting com.apple.ichat.Jabber.plist is more likely to reset the Jabber logins with include Google and Facebook Chat (the app will need a restart).

That sounded promising ..............nope.

Just did a disc repair ...needed work, but did not solve the Message problem.

Keep 'em coming ....I'll keep trying .....

Hi,

When things were GoogleTalk and Chat was added to the Mail Web Page I Enabled it.

I then added the Account to iChat 3 as it was back then.

I have never upgraded (?) to Google+ or Hangouts (although I do understand I may have been moved anyway).

However in my Mail web Pages > Settings for Chat I have this:-

If you can't see the pic it is the central panel of that part of the preferences and Chat is select.

The top line of the setting radio check boxes is "Chat On"

Is GoogelTalk or Chat in Hangouts (whatever it is called now) active in your account settings - Web Mail page or other ?

the bit that I pasted earlier about using Terminal to reestablish the IMagent code worked and solved my seemingly identical problem. Where I was able to launch Messages and FaceTime before, I could do nothing in them and none of my account info was there. Running the line to reestablish IMagent immediately had both working.

That is why I shared it.

FWIW, I got into trouble to begin with by getting dialog boxes asking for passwords for Face Time and Message when rebooting Yosemite. No passwords worked. Apparently that is a known bug. That is when I found that code. I Used it to delete IMagent stuff. Then neither program worked any more. Using the second line fixed that. Toby, have you tried it?

I think I may have found a "possible" clue to the problem. A long time ago I stopped using Mail and started using gmail exclusively, therefore, I do not remember how Mail was configured to link to gmail. However, it is linked, and during this seemingly endless quest to enable Messages, I found Internet Accounts in System Preferences ....Internet Accounts shows a link between my gmail account and Messages. When I try to access the account details for Messages there, my passwords will not work.

Also, I cannot access Mail and get the following alert window. Neither SMTP Server will accept my gmail passwords.

Does anybody understand how SMTP works, and how I can reset the account passwords?

Hi Bob,

You will notice that I did not say it was not valid.

I did point out there was a non Terminal way to Quit IMAgent using Activity Monitor and that this allows the app to Automatically restart.

Hi,

My STMP info does not include my account info like that.

1) For some apps to now access Google you have to set the "Enable Less Secure apps" login process in the Account settings > Privacy (if I remember correctly)

2) It cannot use two Step Verification as well for Messages to work.

In Mail > Preferences > Accounts > The Google account

Use the STMP Button and select the Edit option

It will take you here

The Advanced tab looks like this:-

If you feel it is the password highlight it and use th backspace to delete and then enter it again.

Basically the Mail App make two logins; one to the IMAP or POP server (Fetch) and one to the STMP server (Send)

If you have other accounts and compare them you may find some are using port 25.

This is the most common one used by mail servers fro STMP connections.

In some cases your ISP may only allow port 25 connections to their own server and will not pass on "request" to ones outside their control.

I also have an email address based on an old Dial-up Account. That server will only accept logins from it's Login server (I have to be logged in over dial-up and it will not accept requests coming from my current ISP login to the internet.

Your pic above suggests you have not entered a Description either in the Mail App itself or the Set up for Internet Accounts

Any luck?
