I have a G4 MacMini with 10.4.11 and would like to upgrade to 10.5. I am using MYM software that runs in 9, Will 9 run in 10.5?
How often are you using MYM in 9? You could install 10.4 on a partition or external and bootup to do your MYM work. Run everything else in 10.5. This is how I transitioned my remaining 9 apps to newer apps for later OS X versions.
