Hang up in "Internet Accounts" in System Preferences.

Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.

Send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

Jerrytim, that solved my problem!

Symptoms:

- Messages and MacMail (and others) starts frozen (the spinyball/beachball/pinwheel)

- Many many apps (Photoshop, Preview, Chrome) freeze when I use "Save As" (same spinyball/beachball/pinwheel)

- "Internet Accounts" in System Preferences is empty (I have 4 accounts in there normally, 1 iCloud and 3 Google).

- Finding stuff like this in the Applications/Utilities/Console app

- Log out (or Reboot) will fix the problem (all symptoms are solved). Until a day or two later all symptoms reappear.

Other info:

- I close my lid every night and then reopen in the morning before work, keeping it open all day, attaching/reattaching to external monitor/kb/mouse all day long.

Fix:

- Open a terminal

- Look for the accountsd process:

ps -ef | grep accountsd

- Here it is:

502 322 1 0 Wed09PM ?? 95:27.29 /System/Library/Frameworks/Accounts.framework/Versions/A/Support/accountsd

- Kill the process using the process ID:

kill -9 322

- Verify it has a new ID now:

ps -ef | grep accountsd

- Now shows a new accountsd process (with a different process ID number), and all above symptoms are now GONE. Hooray

And.... here's a one liner to kill accountsd:

kill -9 $(ps aux | grep -e accountsd | awk '{ print $2 }')

It will auto restart next time you access an account (just run System Preferences / Internet Accounts)

So.... Apple. My dearest Apple, Something is going wrong with your accountsd process. It's rotting. Hanging. Or something. I hope your engineers can fix this so that I'm not super-inconvenienced every time it decides to rot again. But now I know how to fix the issue every time this happens, without having to log out, which is a HORRIBLE experience. So, I'll make myself a little script to kill it. Which turns this HUGE inconvenience into a minor annoyance. I dont even like to be minorly annoyed, so I do hope you fix it.. 🙂

More error messages, for helping in people's internet searches. (see my previous response with a bandaid fix).

My console app was FULL of these, with different GUIDs, i'm talking 100's.

My problem still exists of course. Every day or so, I have to run my one-liner command to kill accountsd.

Would love a permanent fix.

Mine is slow to load. After that it seems ok.

Yes. Mine gets to the "Loading Internet Accounts..." listing in the top of the main pane, and then it sits there for as long as I don't get bored. All other panes open quickly. Not this one. I'll leave it for an hour or so, see if that makes a difference. Maybe once a cache is built, it'll open faster.

Yes. Hangs, fans fire up to full speed. Nothing loads - even after long waits. Fans slow down and speed back up again loudly. No other panes can be accessed, Force quite System Prefs is the only way out.

Me too. I discovered this while trying to fix a crashing Mail app which would hang as soon as I open it (when the 'pick an account to add' popup shows). Does your Mail app also crash? Wonder if these things are related.

Another "me too" with Preferences hang. Running 100% CPU. Some weirdness going on in Mail. Also having sync failures in Calendar that seem to be related to internet accounts. It's reporting failures to connect to google and other serves. Works fine for a while after reboot but then things start hanging.

Calendar hasn't given me a problem, but Mail freezes on quit, and Maps won't load -- all on one machine, but they all work fine on another. They're both mid-2010 iMacs, but the one that works is the wide-screen one, the one that doesn't is the smaller-screen machine.

The accounts setup should be the same for both (but I can't tell because Internet Accounts won't load on the one machine).

As for the problem machine: Besides hangs in Mail, I also tried to launch Maps in Maverick after a short time earlier failing to get System Preferences to properly load Internet Accounts and having to force-quit it againt. I think the problem with Maps was Internet Accounts, but I can't (yet) prove it as I have an actual life.

Maps loaded to the point where the menu bar appeared and its location-in-use triangle showed up there as well, but the app did not go further: it did not dispay a window, let alone a map, nor did it instead draw the swirling busy icon despite repeated attempts to get it to either compete loading, to quit (no menus would respond to clicks) or to trigger the icon so it would report as unresponsive in Force Quit Applications (which not only reported it was running fine, but wouldn't force it to quit,either). Maps just sat there, half running and half not, and untouchable.

I had to power up Activity Monitor, find Maps in its list, and force-quit it from there.

This is really starting to bug me. Logging out to the System and back in again to my adminstrative domain on my machine does not solve the issue, either. Neither Internet Accounts nor Maps would work.

Embarrassingly, restarting and going straight into Internet Accounts worked for me; I then disabled Google Mail sync and things resumed normality. I've heard so much negative stuff about Apple Mail and Gmail in Mavericks that I'm not going to use that combination for now.

I'm having the same problems; first noticed in Calendar with most calendars failing to sync (even iCloud ones). I do have a google account in there, which I thought I deleted but came back. I'm trying to delete it again — gotta restart I suppose to get Internet Accounts to open.

HOWEVER — I repaired permissions, which found a ton of errors, and after that Internet Accounts and Calendar worked just fine — for a while. Then it went back to the same issue, and subsequent permissions repairs aren't doing any good.

I'll remove google calendar and see if that does the trick. In fact I can probably remove it entirely, since I check google mail in gmail. Will report back.

OK here's news… after a reboot I was able to open the Internet Accounts setting. I have three google accounts, all of which Mail was turned on for, however I check all those accounts in the browser so I turned 'em all off. I turned off calendars as I don't need that, and everything else too wtih the exception of contacts on one account which I *do* need synced.

So far, Calendar is syncing no problem (all accounts are iCloud), and Messages started behaving again too.

Time will tell if that fixes it, but it's a good start for anyone else with this issue.

I experience the same behaviour for both Internet Accounts ánd iCloud, all the other "sub"panels of Sys. Pref. are working fine...

The problem was caused by dodgy entries in the accounts.plist file in my User Library folder. It appears that either when I upgraded to Mavericks this file gained many thousands of duplicate entries, or maybe these entries were in there before but previously the OSX/Mail combination was more tolerant. When I removed these the problem with Mail disappeared. Here’s what I did….

1> Make the user Library folder visible - in Mavericks this is a lot easier than Lion/Mountain Lion. Simply open up your user directory in Finder, select menu View>Show View Options, and select “Show Library Folder”

2> Navigate through username>Library>Mail>V2>MailData and select the Accounts.plist file. If this file is multiple megabytes (mine was 40+mb) then this is likely the cause of your problem (once sorted mine ended up at 19k in size!)

3> To be safe, make a copy of this file (I placed the copy on my desktop).

4> Using your chosen text editor (I used Text Wrangler but I’m sure TextEdit would work just fine) open the Accounts.plist in the MailData folder (not your backup copy) and take a look. If it’s the same as me you will find hundreds and hundreds of entries for the same mailbox repeated in there. Mine was an old MSN mailbox that I never use any more (I’ve seen in other forums that other Hotmail type accounts also seem to be the culprits in this context). There will likely be two lots of repeated data, one in the XML “DeliveryAccounts” <array> section, and one lot in the “MailAccounts” <array> section.

5> Delete (keeping in mind the need to select the XML sections correctly from <dict> to </dict> completely) all those extra entries that you found, keeping the mail accounts you do need, in the XML and save the file.

6> Mail should open up nice and fast again and not eat your system

7> If this did not work, and causes problems because of over eager deleting in <5> you can replace your broken Accounts.plist file with your backup and try again.
