How do I know what is safe?
If you mean the software you are trying to install, then only you can determine that for yourself if it is unsigned. Even then, I'm not sure how safe it really is.
If you mean right-clicking and choosing Open, then install, that is again for you to decide. However, using that method, as opposed to setting the preferences to allow software from anywhere all the time, is certainly more safe. By leaving the preferneces set to one of the other two settings, rogue software cannot install itself. If you disable the Gatekeeper protection, and fail to re-enable it, you stand a slight risk of rogue software being able to install itself. The method I suggested does not disable the settings. It just allows you to install the software which you have determined to be safe, although it isn't signed.
