Hey! So I'm still getting used to my new iMac and have a couple of questions. Once I've installed an app, iWork for example, can I delete the .dmg file? Or is that what's running it? It's labeled iWork09Trial.dmg Might be a silly question but I don't know if this .dmg is now a copy of the app since I installed it, or if that's still the app itself. I just don't want to accumulate too much clutter. Thank you! One more, I installed Little Snitch a few days ago because it was recommended, I then decided I wanted to delete it and simply dragged any Little Snitch files I saw into the trash and emptied it, but some components are still lingering (like the meter on the top toolbar of my desktop). I don't think that was the right way to go about deleting a program. Is there any way to find all files associated with it? Should I reinstall it altogether (will it even override the existing files?) then do a proper uninstall? Any/all help is appreciated . Edit - Ooh one more. Is there a way to get to extras on Skype? Like the games, mainly. I can't find them D:. I was surprised to find Skype, Yahoo messenger, etc. so minimal compared to the Windows versions. Like, I can't seem to even change the color of my font on Yahoo. Anyway, just mainly asking about the extras .
