1. Our legal folks have some very strict requirements about the
user acknowledging a license agreement before the installation
proceeds. I did find a way to attach a EULA file to a disc image,
mentioned in the Software Delivery Guide, by adding resources to a
UDIF disc image. This was incredibly arcane and involved running
ResEdit in Classic mode, much too byzantine a process to use
regularly. I could not find any information about doing this in a
more modern way. (If one exists, I'd be interested.) Otherwise I
liked the simplicity of the disc image delivery mechanism.
There is a shareware program called "DropDMG" from http://c-
command.com/dropdmg that attach license agreements to DMG images, as
well a many other things.
2. But the larger reason I chose PackageMaker was simply because it
provided an Apple-standard, fairly well-recognized user experience
for installing an application. I also liked the fact that the
packaging parameters were all contained in the PM project file, and
it supported very nicely our legal requirements for license
agreements.
I'm not altogether happy with PackageMaker. I recently released an
update to my software as an installer package. I have had a couple of
failure reports already. One failure is still a mystery. The other is
one that I worked hard to ensure would not fail - it did - once at
least.
I went to using PackageMaker because not everyone knows how to drag
an application onto the Applications folder. I would sometimes get
reports of "I installed the software, ran it a few times, went to run
it today and it has disappeared!". What happened was they rebooted
and the mounted installer disk image had been unmounted. I have not
been able to find an elegant method for determining if the user is
running from the disk image. It would have to be kludgy and I have
releasing kludge.
Recently, I have noticed a nice trick some people are doing. They are
putting a symlink to /Applications on the installer disk image with a
background image consisting of an arrow moving the app to the
installer link.
Given this little trick and my PackageMaker failures, I am strongly
considering going back to a drag-n-drop installer for simple
Application installations. I read somewhere that Apple recommends
that method.
