Manage "Open using Rosetta" in lab environment

I have a room of M1 Mac Minis used for a Digital Art/Printing lab. The instructors like to use a plug-in that has not yet been updated to run natively on Apple silicon, so to use the plugin the students/users have been finding the Adobe Photoshop.app, getting info, and ticking the Rosetta box manually... nearly every time they go to run the app (the user account is removed upon log out and refreshed via script).

I'm curious if anyone has any experience managing these settings. They appear to be set in a plist file in the user's Library folder: ~/Library/Preferences/com.apple.LaunchServices/com.apple.LaunchServices.plist; but I have not had any success trying to manage this with a custom config profile in Jamf, nor does dropping the preconfigured file into place during account creation keep that box checked.

    Hi all,

    i've the same problem, i need to open with rosetta word for a plugin, but i didn't find any solution.

    I've tried to put .plist file in the right directory and also package word.app with setted the flag but doesn't worked

    Just got done working through this so I'll post in case anyone finds it helpful.

    I stumbled across this: https://gist.github.com/WardsParadox/d6a8fbe0c0d1f100b5574188e4bd627d

    (Script called run_under_rosetta.py)

    First off, you will need to push a Python 3 interpreter to run this script on an endpoint: https://github.com/macadmins/python

    I copied the contents of run_under_rosetta.py into a new script in Jamf.

    I added the appropriate shebang so the above Python interpreter would see it.

    For some reason it was erroring until I added a colon on line 120 after (app_path)

    I then added the path to Photoshop 2021. I usually drag an app to terminal and copy the path there. But this script didn't like the slashes that terminal was adding, so I had to remove them.

    So this is the working script:

    In my use-case, a companies (GMetrix) photoshop plug-in wouldn't work without Photoshop running under Rosetta. It's a shared lab, and I didn't want every student having to check the 'Open using Rosetta' box.

    I have the GMetrix install.pkg policy running a recon after if finishes. I also have a smart group called 'Has GMetrix installed'. I have the above script/policy run on a Login hook, targeting the 'GMetrix installed' smart group. So anyone with that app (well, it shows as an installed .app, but it's essentially just a Photoshop plug-in) installed, this script will run when they login. There is a ~5 second delay until the Rosetta box gets checked for Photoshop, but it works. Tested with the latest version of Monterey, but it should work with Ventura I think.

    Update: for some reason, this only seems to work for Photoshop 2021 and not 2022. Not sure why.
