Also tested without success: native sandbox, GNU parallel. Docker is headless and still bound on X11 (not considering the learning curve). I tried with ssh -X, but it seems to work only with X11. Instead, this Skype instance becomes a subprocess of u01's Skype and u02 isn't present in Activity Monitor. Sudo su u02 -c /Applications/Skype.app/Contents/MacOS/iTunes &

Sudo su u01 -c /Applications/Skype.app/Contents/MacOS/iTunes &Īctivity Monitor says that iTunes is running as u01, perfect. So I created 2 additional OS X users, in order for the userspace to be segregated: u01 and u02, plus the main user.įrom the main user's desktop I open the terminal: I'm testing on a Mac OS X Sierra and different Skype accounts (any cocoa app is good for testing). I need to run the same application (cocoa native, not X11) with multiple instances (different credentials) at the same time.
