I'm trying to add a few files into a dmg. How do I create a DMG file from a directory?

Could you be more precise? You can create DMG with Disk Utility, do you want something to automate it (bash scripting...)? –  Loïc Wolff Apr 12 '12 at 16:07
    
@LoïcWolff Nope, no need to be. I didn't know that Disk Utility allowed for that. –  Moshe Apr 12 '12 at 16:15

Some step by step instructions can be found here.

After opening Disk Utility:

  1. Click the New Image icon
  2. Place the contents of folder/directory into the newly created disk image.

If you want to do it from the command line, you can use hdiutil like so:

hdiutil create -volname WhatYouWantTheDiskToBeNamed -srcfolder /path/to/the/folder/you/want/to/create -ov -format UDZO name.dmg

Man hdiutil for more details.

Just what I was looking for! Made a bash script to help automate it for convenience: gist.github.com/AlistairIsrael/5308455 –  AlistairIsrael Apr 4 '13 at 7:15
