I don't have a mac to try it on, but I can read the pdf's on a linux system and on an os/2 system with acrocrap 4.
The cds use acrobat index files, which I am not sure are compatible with acrobat7. On top of that, the menu system is a win32 executable, which doesn't run on macos or osx.
I have been able to read the PDFs using acrobat4 on a pc, but I think that was the version the cd loaded. If I try another version, I get 'looking for updates', then nothing.
