Extendscript STARTUP folder location in /Users/<user> range

I don't use Mac, but what I understood it worked on OsX before some system update, so if I'm right Photoshop code should be adjusted to that change?

No, since it should not be required. Since from my understanding it is just a simple string variable used in a if statement only to prevent other applications from executing the code inside the brackets. For a better understanding, here is the actual code I am testing right now:

var LOCAL_1 = $.getenv("L1");

var LOCAL_2 = $.getenv("L2");

if(LOCAL_1 == null || LOCAL_2 == null){

    alert("Environment variables not present, scripts will not load!");

}

alert("L1 [" + LOCAL_1 + "], L2 [" + LOCAL_1 + "]")

if(!Folder(L1).exists){

    // FUTURE CODE WILL BE HERE

}

As you can see the code is simplicity itself. Outside of Photoshop I setup environment variables L1 and L2, which I then read and report in current script. It works if I browse for the script manually in Photoshop or if I put it inside of

/Library/Application Support/Adobe/Startup Scripts/

or

/Library/Application Support/Adobe/Startup Scripts/Adobe Photoshop/

and restart Photoshop, which will trigger it on startup as I want.

The problem is the writing permissions required by the /Library hierarchy, which would for example for a bash script automated placement/copying require a sudo call, which I do wish to avoid for production level, which would be a script distribution across in the range of 100 employees.

According to the documentation using the ~/Library hierarchy should be possible but it seems that the provided location in the documentation does not work. So the question again, is there another user (~) range location that PhotoShop checks for startup scripts?

BTW, why can't I use the startup folder method (as you said in the previous post), since it is documented as a legit option and is also what I need to automate the process I wish to achieve?
