Auval and Auvaltool not working through SSH

audiomojavessh

I was successfully validating audio unit plugins with OSX 10.11 over SSH. On my new machine which runs OSX 10.14 (Mojave) everything works fine until I try to validate a plugin from an SSH connection. I use the same command in the same directory both in local and over SSH.

/usr/bin/auvaltool -v aumf MyPl Loco

The thing is, using SSH, auval do not detect my plugins (/usr/bin/auvaltool -a), but only Apple default ones. When doing the same on the screen sharing, my plugins are in the output.

  • This does not seems to come from $PATH.
  • This does not seems to come from permission (I have tried a chmod 777 on every .component)
  • This does not seems to come from group/user (I have tried to chown it to diferent user)
  • This does not seems to come from administration (I have tried to sudo it)

So my question is, do you know any SSH security limitation that can break my execution of auval and auvaltool ? What can be different on SSH that could make some execution behaviour changes ?

Thanks.

EDIT: How to reproduce ?

  • Install any non-apple AU plugin.
  • Launch a terminal and:
    • "auval -a" will output the previously installed plugin.
    • "ssh localhost" will connect to you machine through SSH
    • "auval -a" will NOT output the previously installed plugin.

This is a long shot, but I once had to install tmux with brew install tmux (and I already had https://brew.sh set up and ready to run) so that I could graphically log in and establish a terminal session for the user in question.

With fast user switching, you can then return to the log in screen - leaving that one user console session blessed with full GPU and full graphical console permissions and then ssh in to attach to the existing TMUX sessions.

Hopefully someone has a more direct answer, but after several days of bounties and some great comments trying to back into the answer, I wanted to get on the record that a graphical log in does have higher powers and permissions and you just might need that for now if no-one has a better fix for this.
