V.8 In [https://docs.inductiveautomation.com/display/DOC80/Vision+Client+Launcher](https://docs.inductiveautomation.com/display/DOC80/Vision+Client+Launcher) there’s a command line section where it describes the commands for Windows and Linux to launch projects from cmd/terminal. It’s pretty obvious that Linux command should work for MacOs terminal. However, it seems not to work because I can’t find the visionclientlauncher.sh anywhere on Mac. Please some help! ---

Mine was installed in the Applications folder and is called “Client Launcher.app” ---

MacOS can perform this using the open command as well: `open -a /Users/tester/Desktop/Vision\ Client\ Launcher.app --args -Dapplication=MY_APPLICATION` ---

Great @jcoffman thanks, was this part of > [@jcoffman](#): > > --args - that I didn't realized how to use. In addition, I want to add some knowledge. If a project has a empty space between it's better to use \ and not %20 as suggests in docs. Thanks ---

The launcher application should use `%20` - the `\` in JJ’s example is escaping the space in the filename (common to POSIX shells); `%20` is HTML-escaping the space for the parsing logic specific to Ignition. ---

running for MacOS terminal the %20 didn’t work for me, instead \ did work @paul-griffith or @jcoffman I need an advice, now I’m trying to run this command from system.util.execute in a button in a MacOS Client but I can’t make it work. For example, for Windows I need to call “cmd.exe” in Ubuntu there’s not need o call the terminal. How about MacOS? ---

Well, you can do two things: 1. use the `open` command, though you will likely need to do some fancy calling from a bash script or something 2. call the bundled executable within the .app directly. like `...Launcher.app/Contents/MacOS/Vision\ Client\ Launcher -Dapplication=MY_APPLICATION` ---

I understand your point sir, you’re right the %20 would be valid inside a Ignition function. The \ is valid within MacOS terminal. Is good to make that clarification ---

For testing I will just try to launch Vision Client Launcher app first with no project specified I still don’t make it work. In a button script: ```auto system.util.execute(['open -a /Applications/Vision\ Client\ Launcher.app']) ``` But in MacOS terminal ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/3/3f586651995bbaa5e019536f43e5fec18c577852.png) And it opens the app!! For bundle execution: ```auto system.util.execute(['/Applications/Vision\ Client\ Launcher.app/Contents/MacOS/Vision\ Client\ Launcher']) ``` also ```auto system.util.execute(['/Applications/'+"Vision\\ Client\\ Launcher.app"+'/Contents/MacOS/'+"Vision\\ Client\\ Launcher"]) ``` Even giving the full path: ```auto system.util.execute(['/User/localhost/Application... ``` For all of those I have the ![image](https://us1.discourse-cdn.com/inductiveautomation/original/2X/b/be36c55d28b07984ed9a3edef89e935689201f41.png) error ---

Awesome, it worked…the problem was those \ , I should have tried that… Thanks @jcoffman
