OSX quickie... How to make a program install anyways when it says you should delete it.

OSX 10.8 has a nasty bug called Gatekeeper.   It's designed to stop you from installing software outside of the blessed list.  Well even turning it off will not actually turn it off.   Many apps come signed that have a revoked cert because they were for 10.7.  to fix this problem issue the following command in a terminal

"xattr -c "

This will fix the problem for you.  I suggest saving the fixed installer and getting rid of the old one so you dont have the problems later when you need to re-install.
