I'm currently having trouble running The Powder Toy 44.6 on my Mac, which runs Leopard 10.5.8. Whenever I try to open PT, I get an error message saying "You cannot open the application “Powder†because it is not supported on this architecture.". I have no clue what's going on!
I have a similar problem on my mac too. If i try to open any of the mods compiled for mac, it says this:
Vandium's Fork cannot be opened because of a problem.
Check with the developer to make sure Vandium's Fork works with this version of Mac OS X. You may need to reinstall the application. Be sure to install any available updates for the application and Mac OS X.
