On OS X, PL 15 running 64 bit, Topaz Adjust shows in the filters menu but crashes the program.
Running 32 bit (but NOT Rosetta), Topaz Adjust works perfectly.
Running 32 bit WITH Rosetta, Topaz Adjust shows up in the filters menu, but doesn't do nuffin'.
Before it showed up in PL, I had to go to Computer/Library/Application Support/Topaz Labs/Adjust 4/Plugins/ and copy the file "Topaz_adjust4.plugin" to your plug-ins folder.
A guy who's running it successfully in Canvas 12 on Windows says the procedure in Windows is:
Substitute PL for Canvas and you have the procedure.In Windows, Topaz Labs installs itself in its own folder inside the Program Files folder where all Windows programs install themselves. What's necessary is to find the file "tladjust4ps.8bf" and copy it into the Plugins folder for Canvas.
Now -- I suspect that everything the Topaz Adjust plug/program does (it works as an alternative editing program from within iPhoto and I would highly recommend it in that role because it doesn't do the nasty compression with each save that iPhoto does -- in addition to having much, much more functionality, of course) could be done with PL, but the beauty of Topaz adjust is that it presents a whole bunch of alternative presets -- which adjust a bunch of stuff then you can fine tune the sliders.
In reality, I suspect PL could have a whole bunch of Actions that would correspond to the Topaz Adjust presets, but it hasn't. hence I recommend Topaz.
Have a look to make your valuable PL even more valuable. http://www.topazlabs.com/
