If you need a starter-kit for Windows or Mac you can get the full install of DPP for your 1D from the Canon site (of COURSE you have a 1D, you remember the 6-digit serial number, right? starts with zero, has 5 other digits like 13579 or something close, right? I'm not suggesting you lie though, that would be bad).
Then you can upgrade to whatever the latest version is. Not sure where that takes you for Mac, works for Windows though.
