BladePro no longer works on 64 bit Macs. Yet Flaming Pear continues to sell it and say it works with "OS 10.3.9 OR LATER". Flaming Pear either needs to update their obsolete products or stop selling them to unwary customers. Besides, it's nothing but a Photoshop plugin. And now that you can only RENT Photoshop (which costs more than my monthly cable TV bill!), Photoshop plugins are simply a further waste of money.
Fortunately, there are much better & much less expensive stand-alone FX apps available on MacUpdate, the AppStore & elsewhere.
When I upgraded to 64 bit I started using ArtText, a stand-alone app that costs half as much, does way more than Blade Pro & is way easier to use. There is even a very useful free version available on the AppStore. Besides many amateur-level FX apps, there are also many more useful stand-alone FX collections, ranging from the very reasonably-priced JixiPix, to the very costly Filter Forge.
Then, of course, there's always the amazing Gimp, the entirely free open-source alternative to Photoshop. Version 2.8 has even more available plugins than Photoshop (including many Ps doesn't have). Gimp continues to astonish me with all that it can do. As Photoshop gets more out of reach for most people (even many professionals), Gimp is becoming more popular, more powerful and easier to use.
Finally, for high-level professional photographic editing, there are several choices, including two great free open-source apps that rival Aperture or Lightroom. My favorite is LightZone, which is not only quite powerful, but also fast, easy to use & very stable. Photivo allows a little finer control but is also a little harder to use.
