Unable to launch Minecraft as a different user logged on computer

Unable to launch Minecraft with any other user than the user that installed Minecraft.

What I expected to happen was...:
Minecraft started

What actually happened was...:
Error message "Unable to start Minecraft, if you are running from a dmg, please drag to Applications and try again". Screenshot attached.

Steps to Reproduce:

Steps to reproduce this bug on a Mac:

1. install minecraft (as an admin user)

2. run minecraft (it works)

3. switch to a normal user (or a different admin user)

4. click on minecraft icon

5. The error message "Unable to start Minecraft, if you are running from a dmg, please drag to Applications and try again" will appear on the screen

The same error occurs if you launch from the command line.

If you 'su admin' (the user that installed minecraft) then run the launcher then the launcher works. Appears to just be a permissions mistake when minecraft launcher is installed / updated.
