MacOS – When installing an application is there any way to avoid any drag and drop

An application on a Mac is just a folder full of files with a .app extension. However, macOS hides this fact from you and displays the folder as a file with an icon. Now when you download something it's very uncomfortable to download multiple separate folders (without a download manager). Therefore this "App Folder" has to be put inside a single file somehow. This is accomplished one of three ways:

• Using a .zip file (a container that compresses its contents to save space)
• Using a .dmg file (which is a flat file filesystem–as opposed to a hierarchical file system)
• Make an installer (which, however, also has to be either in a .zip or .dmg because installers are folders on a mac, too)

Since most apps are self-contained and do not need anything outside of the app folder, an installer is not only overkill but also slower than just distributing the app folder.

You can obviously launch apps from wherever you want; it's only a custom or a recommendation to put them into /Applications as it easier for you to find it again and it works with multiple users.

The app can do that can do what you want is Apple Remote Desktop. You can drag&Drop files from desktop to desktop and get and push clipboards from and to other computer.

The best set is to have 2 monitors (having the remote desktop fullscreen-ed), so that you can stare at the two computers at the same time. If you don't, you will have a window with the desktop of your second mac.

Another advantage of this solution is to you only have one keyboard and one mouse in front of you. And you can also put the second computer away from your desk. You just need to have it connected to you network.
