Pharos Popup on OSX Lion

Fixing Pharos Popup app on OS X Lion.

My University uses Pharos print servers to manage a few printers on campus and we were running into an issue of the Pharos popup and notify applications not working properly with OSX Lion. As I work for the Apple technician on campus I was tasked with finding out why. The popup installation was setting up the applications to run on startup just fine, the postflight script was invoking the, the drivers we were using worked perfectly when we mapped the printer by IP but what was going on? Through some further examination the two applications were in fact not being properly started either after install or on boot.

I managed to find a work around that caused the applications to run. I manually ran each of them through command line (as through Finder resulted in failure) and magically they worked as expected and now whenever my machine starts up they start on boot without having to manually run them, even if I uninstall the applications and reinstall them I not longer have to manually run them… but why?

voltaire:~ brett$ open /Library/Application\ Support/Pharos/
voltaire:~ brett$ open /Library/Application\ Support/Pharos/
voltaire:~ brett$ ps aux | grep Pharos
brett 600 0.0 0.1 655276 3984 ?? S 2:55PM 0:00.10 /Library/Application Support/Pharos/ -psn_0_237626
brett 543 0.0 0.1 655156 3652 ?? S 2:45PM 0:00.08 /Library/Application Support/Pharos/ -psn_0_233529
brett 608 0.0 0.0 2434892 436 s001 R+ 2:56PM 0:00.00 grep Pharos

I am still not 100% sure why this work around worked, especially when the postflight script included with the Popup package is set to run after installation. The only explanation I can come up with is OSX keeps a library of all of the “trusted” applications, you know that popup that asks you if you want to run a program that was downloaded from the internet, and the and are not being properly added to the list, unless run manually.

I am still looking into a solution that can be packaged with the Popup package and will post more information here when I find out more.
