site_archiver@lists.apple.com Delivered-To: installer-dev@lists.apple.com Thanks for the useful input. I will experiment with building my image on Leopard and Tiger to see if it makes a difference. I also liked the suggestion to dot files instead of hidden attributes to hide the graphic file in the DMG. I think the bless step is only useful if you are building a bootable image but I was desperate so I followed some instructions I received from another source, verbatim. -Michael On Nov 5, 2009, at 11:05 PM, John Gee wrote:

There are two issues with the resulting DMG. First, the original dimensions of the finder window are not preserved when the DMG is opened on a Mac other than my development machine (where it was created). Second, the background graphic, which is a PNG file, is not displayed.

1. On which version of Mac OS X are you creating your disk image and on which version are you testing it?

If you build a disk image on Snow Leopard with a background image, the background image will not be seen on Tiger.

A problem with operating systems is my first guess too. I haven't seen the Finder compatibility documented, but it is likely in general that Finder settings are forwards compatible. If you configure the disk image on your oldest supported operating system then it is likely to be ok on newer systems.

Building on a new system and deploying on an old system is fragile. In particular as noted, Snow Leopard to Tiger has issues. I have been fine using Leopard and deploying to Tiger through Snow Leopard, both the dimensions of Finder window and the background image do display as intended.

2. I don't understand why you need to bless the dmg.

To specify the folder which opens when the disk image is mounted. (Otherwise can get volume mounting silently with no pretty window appearing.)
