I had this error report come up when installing an Apoggee Duet manual on an external bootable drive with Mt Lion on it.Here is what it says:
"Your security preferences only allows installation from mac app store & identified developers".
How do I change this setting? Is it safe to change it?
Imac
In System Preferences>Security change the setting to Anywhere (you'll probably need to unlock the preference panel using your admin password).
Alternatively, leave the setting as is and simply right-click or control-click on the installer package and select 'Open' from the menu that appears. Only do this if you are confident that the download has come from a bona fide source.

Paul_31 has provided excellend advice. I would also recommend reading the current issue of MacWorld (go to your local newstand) there is an article about switching from PCs and one sub article touches on security, I think you may benefit by reading it.
