Hello, Im trying to load OS X Puma 10.1 in virtualbox, but it just comes up with this:

The OS-X Puma release requires OS9 to be run concurrently and also will only run on a limited group of Mac systems of the era. It was mostly a development release than a real consumer release. How about going the newer OS-X/macOS release your system can support. I do recommend getting to Sierra 10.13.x as it is the oldest still supported release but your given system also plays a part here it may not be able to support it.
