Running multiple iterations of LightBurn on Mac OS

By default, Mac OS will only allow you to run one iteration of an application, but if you, for whatever reason, want to run multiple copies simultaneously, there’s a couple of ways of accomplishing it:

You can simply make a duplicate of your Lightburn app

51%20PM

And run them individually.

42%20PM

Or, a better way is to run multiple iterations of a single app from a terminal session or a script:

open -n /Applications/LightBurn.app

The ‘n’ argument just tells Mac OS to open a new iteration.

You can automate this if you create a bash script and save it in your ‘applications’ folder. Every time you click it, a new iteration runs

To create a script, first create the script file:

Open a new terminal session:

I have chosen the name LBMulti for my script.

Enter:

touch /Applications/LBMulti

That will create an empty file in /Applications

Then, edit the file:

nano /Applications/LBMulti

In nano, paste the following:

#!/bin/bash

open -n /Applications/LightBurn.app

; exit

control+x to save the changes to the file, then make the file executable:

chmod +x /Applications/LBMulti

And you’re done.

This will leave a ‘hanging’ terminal window after the script has executed, but you can fix that with a simple option change in the terminal app if it bothers you:

In terminal, select ‘preferences’

02%20PM

In preferences, select the ‘profiles’ pane and the ‘shell’ tab within that

If you want the script to look like the LightBurn app, you can paste the icon onto the script:

Highlight the Lightburn app and hit command+i to bring up the information window. Highlight the icon in the top left of the window and copy it with command+c

48%20PM

Then, highlight the script (which I have named LBMulti, but you can call it anything you like)

24%20PM

Highlight the icon and command+v to paste the Lightburn icon

34%20PM

The script and icon will persist through application upgrades.
