Thankyou @pwalker8 and @odamizu.

That is a learning for me! I had no idea firmware was so impactful in OS X world, or maybe computer world. I realise now I should of purchased an old MacBook and waited until all the apps are mature in 64 bit, rather than this new MacBook Air. Geez...

I will try VM solution (With how-to using the free Parallels lite by imore)

Thankyou for both of your help. Greatly appreciated.
