I got this error:

"CoreTelephony Trace File Error
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"

I tried to solve it by searching similar CoreTelephony errors. Couldn't solve it yet.
Software not working, specially photoshop...

Any ideas?
