(I'm posting this as Commentary because the site won't let me post Developer Notes at present for some reason.)

Privilege Processor does not work with Mac OS X 10.4 Tiger (and may not be fully compatible with 10.3 Panther). I have done some initial investigation into solutions, but haven't completely resolved the problems.

Due to other priorities, I am unlikely to finish this work any time soon. I apologise for any inconvenience this may cause.

Note that Privilege Processor is open source and licensed under the GPL, so any AppleScript developer can have a go at modifying it. I am happy to share the work I have already done with anyone interested - contact me via my homepage.
