OS X: how do I distinguish Intel-only from PPC-/Universal apps?

While rumaging my archive I come across some game titles from Big Fish/MacGames. Can I easily check which are suitable for MG (except the 10-year rule)? Read somewhere about open the executable in HexFind or such and look for FEED-FACE , CAFE-BABE etc. Is it possible with these games too?

You can check the architecture using the file command in Terminal.

Run terminal and type "file" followed by a space. Then browse the app bundle to get to the binary (Appname.app/Contents/MacOS/Appname) and drag this to the terminal.

Run the command (file Appname.app/Contents/MacOS/Appname) and it will list the included architectures.

Thanks! I presume even PPC will show up as I'm in 32/64-architecture.

Yes; MachO binaries have a header at the top that indicates what architectures it supports -- I can't recall how well this method works for the old JOY!PEFF binaries, but those should be obvious that they're either PPC or FAT (68k/PPC).

Right click on the app, click Get Info. Look under General: Kind: Application. It will say PowerPC, Universal or Intel. You can also use System Profiler>Software>Applications to see the architecture of most executables on your system.
