I have several 4D v6.7 clients on Mac OS 10.4 (PPC-based) using Classic. 
I believe 10.5 does not include Classic.

Another potential complication is you might need a PPC-baed Mac for 
Classic. I'm not sure whether Classic works on an Intel-based Mac.

Any Mac that'll run Classic, e.g. a NON-Intel Mac. The Mac OS has to  
be Mac OS X 10.4 or earlier to allow you to run in Classic. Mac OS  
10.5 killed Classic. It's possible to run Classic on an Intel Mac  
using SheepShaver, but I've not spent the time doing it, so I can't  
comment based on first hand experience. But once it's been converted  
to 4D Ver. 6, bringing it to 4D 2004 or V.11 will be fairly straight  
forward.

Watch out for the old externals, aka plugins/bundles. Old style Form  
Events still work. Popup arrays are now handled differently. Serial  
Port commands addressing the serial ports work much differently, as  
the "Printer Port" and "Modem Port" of the Mac no longer exist.  
They're all USB ports. Subtables are verboten in 4D V.11, so promote  
them now if possible. Sub-subtables don't work at all in 4D 2004. The  
Method Editor won't compile any references to them. Lots of things to  
look for.

If at all possible, borrow an OLD Mac that'll allow you to run the  
old version. This might make it easier to test the new upgraded  
version so that you can compare functionality, old code vs. new code,  
User interface issues, etc.

Just finished doing a project along these lines a couple of months ago.
