Marcin Wichary:
Mac’s operating system has a peculiar way to install apps. An app typically arrives in a file with a .dmg extension (it stands for “disk image”; my brain always reads it as “damage”), which upon double clicking becomes a kind of a drive. You go inside the drive, and there is the app icon.
But the journey isn’t over. While you can run the app from the virtual drive, the drive will eventually disappear after the reboot – or if you eject it – so it’s in the app’s interest to suggest a more permanent home for itself.
