Can I run iWork 9 on my PowerBook G4

Hello,

Yes, earlier versions of iWork '09 supported Apple's Universal Binary which means it should work on Power PC. I believe the last version of iWork '09 that Apple shipped was strictly Intel only.

No.

Hmmm, https://en.wikipedia.org/wiki/IWork says '09 is Universal?

Thanks. :)
