I've recently updated my os from 10.4 to 10.6 and have been faced with some rather unexpected changes in the new version of PackageMaker 3.0.3. To put it another way, I'm having to make choices I didn't have to make previously and not really being a full-on Mac user, I'm not confident in all my choices, soo... 1) Within the package contents section my main app is listed with me (my name) as the owner, admin as the group and mode as drwxr-xr-x. These are default settings. Is this correct for my users? Apple's PackageMaker User Guide pdf states "In most cases, the owner should be root and the group admin." I tried to change my name under owner to root (since i don't exist on my users machines), but the build gave me warnings saying "User ID 0 does not match 501 of root volume /Applications/MyApp.app. Make sure to have disk permissions repaired with Disk Utility". Yet, when I click "Apply Recommendations", it chooses my name as the Owner again! what the hell? 2) To see the differences between the new pmdocs and old pmproj files, I've opened my old .pmproj files as well as created new .pmdocs. For some reason when creating new ones PackageMaker defaults the Package Identifier to com.CompanyName.AppName.companynameAppName.pkg instead of the shorter, more intuitive com.companyname.appname like was used in my pmproj files. my question is, isn't this used for updates and don't i need to be consistent with this identifier for that reason? i don't understand why it chose that as the default name and why .pkg is at the end, so if someone could enlighten me, i would appreciate it!
