CoreTelephony Trace File error

Hello all,


After installing an SSD and using it as primary drive for my Macbook Pro (running El Capitain), after each restart I get a "CoreTelephony Trace File Error" with the above message:


A file operation for CoreTelephony tracing has failed, you may be out of disk space. Details 'Error opening file /tmp/ct.shutdown, err = Operation not permitted

Does anyone face the same error? I have already found some solutions, but they haven't helped for my case.


Any help will be much appreciated!

MacBook Pro (13-inch Mid 2012), OS X El Capitan (10.11.4)

I actually tried all these suggestions with the terminal command and changing permissions and even tried the advanced option of the user account in system preferences but none of them worked.


What did do the trick was an archive and install and run all your software updates and this resolved the issue. It also solved the problem of photoshop crashing. Just make sure to backup your data first before reinstalling OS X 10.11 again and you should be good to go afterwards.

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 ;-)
