Hi does anybody know of any guides or images that can enable you to install OS's as old OSX 9 and OSX 8 on VirtualBox? I have some iso's of the install CDs but I just letting them boot up does not do much. I knew nothing of Mac at the time these were made. I am running VirtualBox on a Mac Pro with Yosemite. Thanks

It's not possible. Mac OS8 and Mac OS9 will not run on an Intel CPU. There used to be an emulator that would run early Mac OS's but not sure it's still around.
