Also, check out the available buttons on the dialog---"Cancel" and "Eject disk image". I'm guessing that "Cancel" is the one you need to click to say "Cancel the warning and mount it anyway", which in other contexts is known as "OK". Argh.
But neither button says "trash it", and "eject" in the context of disk images just means "unmount". So now I'm even less clear about what those buttons do.
And since ordinary users will never figure that out, Apple needs to change the dialog or accept that they have now, officially become the big brother they fought against.
And do you honestly believe that it is a bad thing that ordinary, unsavvy with computers users will not immediately be able to install applications from unverified sources?
Yes I do. At least as long as it is required for them to be signed by Apple issued certificates.
As for the Big Brother reference, it was not name-calling. Apple specifically said we are not like the faceless, nameless corporate nightmare (then IBM, later Microsoft). Apple was different.
And now they have looked their customers computers down harder than Microsoft ever did and have taken from their users the freedom to choose. They have become what they fought against.
Mounting a disk image is a step before trying to run the program. The dialog shown is what you would see when you first download the app in a .dmg file. Then you mount the disk image, and either run the app from the disk image by double-clicking on it, or copy the application to your computer.
