Which of the following macOS file types requires mounting before installation?

A.pkg

B.zip

C.app

D.dmg

Show Suggested Answer

Suggested Answer: D

The .dmg file type in macOS requires mounting before installation. .dmg files are disk image files used to distribute software on macOS. When opened, they mount a virtual disk on the desktop, from which the application can be installed. Other file types like .pkg, .zip, and .app have different processes for installation and do not require mounting in the same way.

Wait, is .dmg the one that also comes with a complimentary trip to the Genius Bar? I always get those mixed up.

Easy, it's .dmg. Who doesn't know that macOS installers come in that format? It's like the universal language of Apple software.

I always thought .dmg files were just disk images, didn't know they needed to be mounted for installation.

Hmm, I think .pkg is the one that requires mounting. Or was it .dmg? I'm not 100% sure.

Definitely .dmg, I remember that from my last macOS upgrade. You can't just double-click and install with that file type.

I'm pretty sure it's .dmg, that's the file type for disk images that need to be mounted before installing.

I've made the mistake of trying to install a .dmg without mounting it first, it never works.

I think the answer is D) .dmg because it's a disk image file.
