CoreTelephony Trace File Error

HI,

I contacted apple support and they advised the following which worked for me. I didn't need to go the sierra option, but if the reinstall OS X doesn't work, then sure try the last option.

Steps

Let’s restart your Mac into OS X Recovery by restarting and pressing Command-R upon restart and holding for one minute. From there, let’s click on Disk Utility > click your Macintosh HD > click First Aid at the top.

This will ensure there are no underlying issues with the hard drive itself.

From there, if there are any hard drive issues, that would be an indication of a hardware issue. However, if there aren’t, we’ll want to close out of Disk Utility while still in recovery mode, then choose Reinstall OS X. ( its the second option) This will reinstall the current version of OS X and only reinstall system files without erasing any user data, and can often times fix issues like this where it’s returning a trace file error. note: if you are not connected to ethernet, you will need to connect to wifi by clicking on the wifi icon in the top right of the recovery screen.

Another option we can use to get this resolved in the event reinstalling OS X doesn’t work is upgrading to Sierra and then attempting reinstalling after.

Same problem here, 21.5 inch late 2013 iMac, El Capitan

Man, there are a lot of people running into this error recently, but still, there is no way known to me to fix it...

Install MacOS Sierra version 10.12 - the Trace file error will go away.

I purchased new, a late 2015 model that came with El Capitan and is currently on version 10.11.6. It has only started displaying this pop-up upon log-in in recent weeks. Not unlike the iPhone/iPod Touch MyMusic autoplay malfunction (i.e., upon USB connection) that Apple Forum members have been screaming about for several years now, I see no helpful response and/or even remote concern on Apple's part with these annoyances and user-UNfriendly errors. Even the "geniuses" at The Genius Bar cannot offer any useful suggestions for addressing these system failures. They should consider a new marketing strategy based upon "sincerity" and "transparency", employing the catch phrase, "There are no solutions, only problems. 😠

Problem solved!

Had mostly the same info: iMac Late 2015, El Cap etc. Tech support tried EVERYTHING. Only thing that instantly worked was to reinstall the OS from Recovery mode. Everything worked perfectly. No passwords to reset, nothing to re-authorize. Seemed a little faster too. Should've done this immediately and may in the future when things get buggy. 🙂

Same problem here too, new iMac with El Capitan. Coretelephony error popped up yesterday without any changes/updates/installments etc to the system.

Annoyed! What did Apple do here?

Try reinstalling the OS from Recovery mode. Should work fine. Let us know.

Similar symptoms here, error first appeared last week, not obviously linked to any upgrades of the OS (10.11.6) or Skype or similar services although I do use various browser-based web-conference systems which often seem to download a plugin. Changing the permissions of the /tmp directory didn't help me, but a reboot in recovery mode and a re-installation of the OS did fix the error message.

How do you switch back to Yosemite? I tried, but it wouldn't let me (sorry, I'm not too tech-saavy). Thanks for any help you can give.

That's what I did and the message has gone away. More importantly I bought a new plugin for FCPX and the installation consistently failed. Having reinstalled the OS (OS X El Capitan 10.11.6) using option under recovery mode the plugin went in and is working perfectly. I even got the shopping done while the OS was reinstalling!

The other thing that didn't work was Parallels (some error message soon after launch) although, interestingly, VMware Fusion did work. Now they both work - happiness.

I really don't feel like dicking around with a whole bunch of different, often complicated, solutions that work for some users and not for others. Am I naive to think that if I just wait there will eventually be an update that will address this problem?

Same problem, different error..

What file is that and why doesn't it have access to it?

Apple wanted to wipe my machine or accuse my 2 week old machine of hardware failure. I cannot call the people that work at the bar geniuses. This from another thread fixed my problem. Kudos to auroratom!

I found my solution! This is permission problem with var catalog '/tmp'. If You try to change permission this catalog, OS X do not let this change because, in system there is 'System Integrity Protection'. This SIP must be disabled before You change permission.

Try this:

1. Reboot your Mac into Recovery Mode by restarting your computer and holding down Command+R until the Apple logo appears on your screen.
2. Click Utilities > Terminal.
3. In the Terminal window, type in 'csrutil disable' and press Enter.
4. Restart your Mac.
5. After restart Mac, try to change manual ( command: 'sudo chmod 1777 /tmp' ) or download app: ( I recommended this utility app to do this: OnyX 3.1.8 for OS X 10.11 El Capitan - download link: http://joel.barriere.pagesperso-orange.fr/download/1011/OnyX.dmg ) 5.1 In the app, select Maintenance -> Permissions, and hit Execute. This fixes all permission problems ( including changes permission '/tmp' to correct ).
6. When the process is over ( OnyX app ) or command 'sudo chmod 1777 /tmp' works, just reboot Mac.

Now, when You changed permission, need to Enable 'System Integrity Protection'. Do this like step 1 to 4, with change: 'csrutil enable'

1. Reboot your Mac and holding down Command+R until the Apple logo appears on your screen.
2. Click Utilities > Terminal.
3. In the Terminal window, type in 'csrutil enable' and press Enter.
4. Restart your Mac. It's done :-) It will be work :-)

I hope it will help! Sorry for my English, I'm still learning ;-)

As others have noted, this reinstall also fixed installation problems with some othee programs - the Flash plugin for Safari in my case.
