Xaviou,
The Mac DMG build using the SF files ends up being different to the DMG file you have. The differences are related to the DMG installation process where with your DMG it uses the extra files to show the drag and drop dialog so the end user does not have to manually (like I have to do) drag the C::B icon onto the finder application dialog.
Can you supply the additional process/files so they can be included in the SF C::B repo? Even a link to the files or repo and then I can create a ticket and include the files as a patch to save your time.
Thanks,Andrew
