Packagemaker and destination folder
 

I am trying to find out if it is possible during an install to read a .plist file on a user's system, and install a file into a location listed in that .plist. Anyone have any ideas how to do this, and if it is even possible??

Yes. But PackageMaker is EOL product i don't really use it as other Tools exist that have always done a better job ( Iceberg http://s.sudre.free.fr/Software/Iceberg.html (FREE) or Packages http://s.sudre.free.fr/Packaging.html , Composer ( Commercial) and good for snapshots.


So you would have a pre-install script that would read the contents of file and determine if to continue i presume ? Then if all is Ok it continues to install a plist or manipulate it using Plistbuddy ;-)
