The latest version of MacOS X 10.4 is MacOS X 10.4.11. It is still supported by Apple. Only yesterday, Apple released a security update for this OS. I have no idea why you would even consider that MacOS X 10.4.9 would render things that worked under MacOS X 10.4.8 inoperable. Classic works fine under every version of MacOS X 10.x up through MacOS X 10.4.11. This includes MacOS X 10.4.9. Whatever capability you have in MacOS X 10.4.8 you will retain in MacOS X 10.4.11.Once a year I have to launch OS9 on an old Quicksilver Mac for a very profitable project. Currently I am running OS 10.4.8.
Can I upgrade to 10.4.9 so that my son can update iTunes and still launch Mac Classic?
Thank you.
