What the **** is TCCD?

Hey folks -

I have a fresh install (format, install from thumb drive) of 10.8 on my Mac Pro in the office. I've been having problems with Mail.app, Calendar, and Contacts when I configure them to connect to our internal MS Exchange server. Specifically, they'll sometimes lock up and need to be killed from "Force Quit.." menu.

Digging into it a little further, I see this process running amuck:

camshaft# ps auxww | grep tccd

jvp 3592 99.7 0.0 2500120 2728 ?? R 4:36PM 986:31.32 /System/Library/PrivateFrameworks/TCC.framework/Resources/tccd

If I kill that process, then each of the aforementioned apps unlock and continue running without a problem.

Any idea what tccd, or the TCC.framework is part of?

I'm kind of confused what that article offers as a solution to tccd overusing resources? Hazel is some 3rd party software right?

TCC stands for Transparency Consent and Control and does interact with contacts but it is more related to getting a users ok for a particular process behaviors. A good example is when your iPhone asks if you'd like to give an app access to something, like the camera or your location. Processes ask for permissions too on macOS but they usually require you to enter an admin password.

It is disappointing however that the tech support and really more like receptionists who are definitely under informed than technical "experts".

Even more problematic is they're sort of the end of the road. They can submit a Request for Technical Assistance to someone in engineering but that's a long shot since they're hesistant to even offer that, it's really playing telephone with difficult to understand issues, and you're unlikely to even get a response--at least in my experience. It's funny too the documentation for everything is online (open source and developer docs). Apple devices get a reputation as a black box but I think it's really just a laissez-faire attitude from users who are likely subconsciously reluctant to face reality.

Hazel is/was a fairly popular third party add on three years ago when that post was written. That's two versions of Mac OS ago. I'd look for more recent information.

It looks like it is responsible for managing which applications have access to your contacts. The similarly named tccutil is a command line tool to manage your privacy database. tccd has a database file in each user's home directory ~/Library/Application Support/come.apple.TCC/TCC.db that appears to store which apps you have allowed and denied access to for your contacts.

I noticed this process using more CPU than I'd think would be necessary (5-13%), but it seemed to drop down after 10-20% minutes of being like that. Certainly seems like it might be a little buggy.

Thanks, that makes perfect sense.

Is your setup connected to an MS Exchange server (Mail, Calendar, Contacts)? Mine is, and I suspect that's a contributing factor.

Mine is not, no. I do have GMail, Twitter and iCloud configured in there though. The only apps currently in tccd's database are Adium, Alfred, Postbox and Chrome.

Cool, thanks. I actually just decided to nuke it from orbit and let the system rebuild the db file. And I've since disconnected the 3 apps from our Exchange server (in favor of going back to LookOut.. bleah).

I'm frequently finding my tccd process running at 100% on my 2011 MacBook Pro, ramping up the fans. System Prefences then fails if I go near Mail, Contacts & Calendars or Security & Privacy > Contacts .

Can I just delete the TCC database without dire consequences and start again?

I would like to detele this tcc database or fix the permissions on it. I have no idea where it is stored - do you?

As tehnoir mentioned TCC.db is in the users home directory ~/Library/Application Support/com.apple.TCC/ . You can get there by pasting that path into Finder > Go > Go to Folder...

I deleted my TCC.db and have denied access to all applications requesting it. So far no problems since. (It was still playing up under 10.8.1)

I get this error:

TCCD quit unexpectedly

Application Specific Information:

database error: attempt to write a readonly database (183)

abort() called

Ever since I installed OS X 10.8 I keep getting this and believe me, it is annoying.

I verified access to the folder ~/Library/Application Support/com.apple.TCC/ and the tcc.db file in there - all is ok. Even deleted the file. Still - this does not seem to be causing it.

Thanks

Hello Cristian,

I got the exact same error as you, and the Mighty Google has no clue about it.

The tcc.db file is here too, permissions OK. But every time I launch or quit any program, TCCD quits unexpectedly. Any solution?

No solution so far. This gets more and more anoying. I really have no clue what to do. Did you run disk utility to fix permissions?

I re-installed the system. I fixed the permissions by booting from the Recovery partition, starting terminal and then there is a utility to fix permissions that goes deeper then Disk Utility: resetpassword. This did not solve anything. I also used ACL Fix - a utility that solved some permissions problems for me long ago - still nothing.

I even used a command-line LSOF to find out which files TCCD accesses before it crashed and could not sort out what is going wrong. Below the details but it's all garbled up because of the size.

I called Apple support and they don't have a clue even what tccd is - they asked me if I use a software called virtual DJ... :-( And it's built into the OS X.

I have a particular setup on my MacBook: I eliminated the DVD and put in the 750Gb hard disk and in its place I installed and SSD drive. I can boot from both the old hard disk and the new SSD. I share the same user folder. The installation works great, I can boot from the old hard disk and the ssd and I do not see a difference as a user, I keep exactly the same desktop, mails, settings, files, etc. The one obvious difference is the speed from the SSD. It boots up in seconds, whereas the other boots up in minutes - this is just to give one example. The OTHER difference is that I don't get that tccd crash from the HDD - it work perfectly.

Anybody has any useful ideas?
