问题:

I want to create a dmg file for my Mac project. Can someone please tell me how to do this? This being my first Mac project, I do not have any idea how to proceed. I also want to give the user an option of running the app on start-up. How do I do this?

Thanks.

P.S. I also want to add a custom license agreement.

To do this manually:

Method 1:

Make a folder with the files your DMG will contain.

Open Disk Utility (It's in /Applications/Utilities/)

Go to File > New > New Image from Folder (Cmd + Shift + N)

Choose the folder containing you files
Make sure "Compressed" is checked, then set where you want to save the created DMG

Method 2:

To do things like setting a background image can be a bit convoluted (You basically add the background image to the DMG, set the windows properties to use that image, using the command line you move the background image from background.png to .background.png to make it hidden)

I would recommend iDMG, which makes things a bit less tedious.

You can also script the creation of DMGs using the command hdiutil. Something along the lines of

hdiutil create -srcfolder mydirtodmg mydmg.dmg

As for the custom license agreement, you should look into the tool included with the Developer Tools "PackageMaker" - it's pretty self-explanatory. It's in /Developers/Application/Utilities/

If you need to add a custom EULA to your disk image, this page describes how to do so using command-line tools. The gist of it is to use the template software licensing agreement resource provided in Apple's slas_for_udifs_1.0.dmg, modify the resource with your EULA text and inject the resource back into your disk image file. (I include brief instructions below in case the above link becomes unavailable, and to update the search term it provides in step 1.)

Using your Apple Developer account go to the Downloads page and search for Software Licensing for UDIF
Download and mount the disk image

In Terminal:

cd /Volumes/SLAs_for_UDIFs_1.0 DeRez SLAResources > /tmp/sla.r

Edit /tmp/sla.r in a text editor, updating the content of the data 'TEXT' (5000, "English SLA") resource to contain your new license text.
Unflatten the disk image file that contains your installer:

hdiutil unflatten installer_image.dmg
Add the edited license resources to the image:

Rez -a /tmp/sla.r -o installer_image.dmg

why don't you just run a script from your xcode project. try something like this:

# be sure to check the man page for hdiutil # it is very powerful and has tons of options...  hdiutil create -megabytes 54 -fs HFS+ -volname awesome_app_install myAwesomeApplication.dmg hdiutil mount myAwesomeApplication.dmg cp -r /build/Release/AwesomeApplication.app /Volumes/awesome_app_install/

then save your script as something like 'makeDMG.sh' and in your target,

select add->new build phase->run script build phase
and drag your script into this build phase.

once you've done all that, then when you build your project the script will create the disk image and copy your release build into it...

of course you should spice your script to flavor... these three lines are just the raw meat

ps: your custom EULA should get built into your packagemaker project (which you can also script very nicely)
