Currently you can not install OSX on non-Apple hardware. If you have a Mac you can set up dual booting with windows or linux using either Bootcamp from apple that lets you boot into one operating system or another. There are also virtualization options like parallels desktop that will run windows like an app in OSX.
I have installed Ubuntu on an HP 7100 with 2GB ram on an 8GB USB flash drive. It booted ok.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
