Olol, well that's totally different.
K, so I gather you've dragged the Toribash app folder to your drive & you're not trying to run it from the .dmg?
Anyway, assuming you have copied it to your drive you need to do the following:
Click the Toribash icon
File menu -> Get info -> Ownership & permissions
You can set it up so you have full read & write access there.
If it's greyed out or missing, then your Mac account isn't admin.
