I have attached a compiled test app that should tell you what types  
Photoshop is providing.  I also attached the source code to the app.

You can decompress the .bz2 file with bunzip2 or bzip2 -d.


$ gcc NSPasteboard_types.m -Wall -framework AppKit -framework  
Foundation -arch i386 -arch ppc -o NSPasteboard_types

$ file NSPasteboard_types
NSPasteboard_types: Mach-O universal binary with 2 architectures
NSPasteboard_types (for architecture i386):	Mach-O executable i386
NSPasteboard_types (for architecture ppc7400):	Mach-O executable ppc

This is what it looks like after having done an Edit->Copy in the  
Gimp's window.  I think that the NSPasteboard transparently happens to  
provide PICT in this case, since we set a TIFF.
$ ./NSPasteboard_types
type public.tiff
type NeXT TIFF v4.0 pasteboard type
type com.apple.pict
type Apple PICT pasteboard type

Please tell what it reports after you have done a Photoshop Edit->Copy.

In fact, anyone that is having trouble pasting from a Mac app to an  
X11 app should give it a try, and send us the results.

Thanks,

George
