Description of Issue

Nothing has changed in my system, but I’m receiving this error message and tried to re-install with no luck. My actual server is sonicore and I use my computers to control that. My other computers work, but I cant get past this error message. Please help.

I had the same error this morning.

I found another post with the same error.
I followed the instructions below in the Mac Terminal app and this cleared the issue:

cd /tmp
sudo chown $(whoami) /tmp

you may have to enter your mac password after the last command.
This worked for me.


That worked!!! I would have never figured that one out!!! Thank you Marc!

Thanks Marc, the command helped me out as well.
