OT: How to make an app accessible for all users on Mac?

[Tiemo Hollmann TB]

Hello,

I am missing some basics of Mac handling. When copying my app folder
(including several apps) out of a DMG from CD into the program folder on HD
as an Admin, only the Admin can "see" and start my app. Every other user
doesn't see my app folder.

What do I have to do, that my app is accessibly for every user? Can the
Admin set any permissions on my folder, so that it is accessible for
everyone? If yes, where and which rights?

Thanks for OT coaching
