How do I install applications from a .dmg file? [duplicate]
A .dmg file is kind of like an USB stick in a file and can be handled more or less the same way. To install from a .dmg file you usually do the following:
- double click the .dmg to make its content available (name will show up in the Finder sidebar), usually a window opens showing the content as well
- drag the application from the .dmg window into /Applications to install (may need an administrator password)
- wait for the copy process to finish
- eject the .dmg (by clicking the eject button in the Sidebar)
- delete the .dmg from Downloads
