Requesting encryption of local Joplin data (at rest encryption)

I only became aware of the --profile switch as it has been mentioned on this forum as an unsupported feature. I am sorry but I am not a Mac user so I cannot tell you how to do this. All I can say is that on windows you just append --profile X:\drive\and\path\to\profile\dir to the executable path in the properties of the program shortcut icon. Is there a Mac equivalent of shortcut properties?

Edit:
Either of these help?
