How am I a dmg installer that will automatically open after boot?

Question

I saw some dmg that not only mounts after boot, but also copies the installer to the download folder and opens the installer in the installer application.

I do not know how to do that?

Can anyone help?

Answer 1

DropDMG works great for me:

I do not know how to do it otherwise (free alternative / manually).

Answer 2

I did not see the dmg files opening automatically, but it was possible to automatically open the folder after the user installed the dmg file.

Once you have created the dmg file, mount it, and then run the following command:

blessing - folder / volumes / TITLE - folder / volumes / HANDBOOK

NAME is your installed folder name, and DIRECTORY is the directory you want to open automatically, often NAME and DIRECTORY are the same.

Answer 3

the --folder option --folder not needed if dmg is required to automatically open the finder folder window after installation

 bless /Volumes/NAME --openfolder /Volumes/DIRECTORY 

NAME is the name of the installed folder, and DIRECTORY is the directory you want to open automatically, often NAME and DIRECTORY are the same.
