You can try something called fhred on the PC:

I have used Mac Coder 3.0 briefly for Mac, but find fhred easier, even if it requires swapping files to my PC. Find Mac Coder here:

The other option is to send me stuff. I have Photoshop and as long as I know where you got the files from, I can contact the author and get permission to make necessary changes. Then I can build a depository of actions files...and that would be most helpful to a broad number of users.
