Then just that we have to access the unit in question and execute the file so that it is installed or executed.
It is necessary to take into account the type of file that is, since in some occasions, an actual installation is not performed on our Mac, but the application only runs, so if we subsequently delete the .DMG file we will lose access to the application. In these cases, if it is an executable application, we must drag the file to the applications.
Restore content in a unit
If, on the contrary, it is an image that contains a copy of a unit, it will not help us to access the inside of the file to consult it if we are not going to be able to access the data or make use of the application. In these cases, we must use Disk Utility, with which we can select both the file in DMG format that we want to restore and the unit where we want to do it quickly and very easily.
