Having the exact same issue as rgorelik. This issue appears on login of any user on my mac mini and when I attempt to connect to network drives, disconnecting me from said drives the second the message pop-up. Any ideas are greatly appreciated.

I am getting this coreTelephony error and a whole lot of the other trouble after updating to 10.11.1.


My system is a 2013 Mac Pro with the home folder located on a second SSD connect via Thunderbolt, and that seems to be the problem.


I have been running with developer's preview of El Capitan since it was first released. Previous updates did not cause any problem. Only this one.


Symptoms:

1. The coreTelephony error dialog

2. All settings are gone. All of them, and I cannot set any preferences. The system cannot remember any setting change: e.g., I can go into the settings for the trackpad, change a couple of things, exit, then go back in immediately and the changes are not there.


Other people posting here mentioned that having the home folder on a separate drive might have something to do with this problem, and it does, I think. And here is why. Simply going into the User and Groups pane of system settings and pointing to the home folder on the external drive does NOT fix the problem. However, if I copy my home folder back to the boot drive (SSD) and point to that, all is well. It simply will not accept having the home folder on that external drive (a Samsung SSD). Someone suggested that you had to have another admin account of the boot drive for this to work, but I did that and it did not help.

What is really strange is that even doing a restore of the system from a Super Duper backup from prior to the 10.11.1 update does not fix the problem.


So I am up and running, but I don't want my home folder taking up space on my boot drive. I will keep experimenting and report back if I find a solution.

Just my 2 cents,


I have a Macbook air that I have partitioned so i can have the /User folder on the other partition.

I created an admin account on the Mac HD and in system prefs told it to locate the user folder on the other partition. This works no problem!

So I then used a symlink to create a link from the Mac HD to the partition. I created a new user account and now get this same CoreTelephony message.


My Admin account still works fine, just the test account is the problem.


From what I can see, the system is doing something funny with how its reading the location of the user folder, or in that ball park.

When logged into the admin account, the user folder is the house. When logged into my test user, the user folder is still a folder.


I hope this helps, this issue is driving me nuts!!

" CoreTelephony Trace File Error, a file operation has failed, you may be out of space"

I have Macbook Pro (mid 2012) retina. I did an update to El Capitan and got the same error. Then the Macbook Pro shut down. Now when I try and bootup I just get a crossed out circle on my screen. The weird thing is that my Boootcamp partition still works fine.

Any suggestions?

Sure. Thanks for your reply.


I am running El Capitan on a Mid 2012 macbook pro retina (256gb SSD with separate Bootcamp partition)


So, here is what happened.


Installed a run of the mill date to El Capitan this morning. Get the error " CoreTelephony Trace File Error, a file operation has failed, you may be out of space ". The computer shut itself down and on restart I see a circile with a slash through it like so

https://support.apple.com/en-au/HT204156

Scrolling down you can see that this is the "prohibitory symbol" meaning that the computer can't find the right start up folder.


My Bootcamp partition still works fine though as MS Windows starts up properly. I note that the Internal MAC SSD is not visible or accessible from within Windows.

I have tried all of the usual things via Recovery folder.


1. Tried an extended Hardware Test and no trouble found.

2. Tried installing a new copy of the existing OSX but the Internal SSD is not visible as a destination

3. Tried repairing via disk utility but it failed. It shows zero available space on the SSD and listed missing threads and says 'Volume needs minor repair'. The SSd is greyed out in utilities, but Bootcamp partition is not.


Hope that helps.
