Many apps are installed by the "drag it into the Applications folder". Is it true that usually, if you copy that app (which is a
.app folder`) onto another Mac that you have that has the same OS X version or higher version, then the App should work too?
(unless it is not supporting Rosetta apps due to backward compatibility).
Some apps are installed by running a program, and go through the "Where do you want to install to", and "Agree with Terms?", etc, etc, and probably those apps can't be properly installed by just copying the
.app folder to another Mac?
(I need to do this because VLC 2.0.3 can't play some format of rmvb files, and I need to install 2.0.1 to another Mac and the downloaded file is missing, only the VLC.app folder is in the Applications folder.)
