How to use multiple A12 Windows on Mac?

Hey there,
quick question for my Mac fellows.
do you know how you can open two A12-“Instances”/Windows on Mac simultaneously?

Hi @julius-low-kernel,

do you mean running two A12 applications (or maybe one application but in different worktrees) locally or opening the SME/Preview App?

Hey Denise,
I mean two SME Applications, so that I can see two different Workspaces at once.

hi @julius-low-kernel ,

On Mac if you want to run 2 or more instances of SME, you can try to run this on terminal if you have A12 Tools folder in “Applications”:

open -n -a "Simple Model Editor"

Or if you have a specific path for a specific version of SME you want to open, you can just simply copy the path to that SME instance and:

open -n -a "<Path to your SME app>"

For example:

open -n -a "/Applications/A12 Tools - 2025.06-ext4/bin/simple-model-editor/12.4.1/Simple Model Editor.app"

That you for your help!
