I think the problem of Lang is different, he says: "The problem is especially with GEM, as in this case I have double lights turned on and everything is too bright." It is more a problem of the patch launching twice in the same pd instance, specific to OSX 10.7+ (IIRC)
yes I've seen this after the mail was sent...
Under osX, to launch two pd instances you just have to start them from terminal. Nicolas
not under maverick...

I had same problem with using init.d script from svn, this launches pd twice at bootup, --no-gui didn't change anything... I resolved it by restarting from an howto page:
https://help.ubuntu.com/community/UbuntuBootupHowto
by the way thanks for the lock-file trick, I had once tried to launch several pd instances on OSX maverick, it was only possible by removing lock-files, really annoying...

Dear list, is there a way to avoid that a patch which is run from a script either from crontab or just autorun from the system runs twice? I heard about --no-gui solution, but never managed to use it on Mac.
i don't know how "--no-gui" is supposed to help you here. it only might obfuscate the fact that two instances are running...
i can think of two simple ways to avoid double runs:
- setup a shared-ressource (a lock-file): when the script starts it
checks for the lock-file; if it is not there, it will create the lock, launch Pd; once Pd is finished it will remove the lock; if the lock *is* there, the script will exit immediately. see flock(1) on linux and shlock(1) on osx.
- stop all running instances of the patch before starting it.
usually you would just do something along the lines of
pkill -KILL pd, before starting a new instance of Pd.fmasdr IOhannes
