Mac OS High Sierra on VirtualBox on Linux/Ubuntu 16.04/Xenial

1. 1. Need a way to download the install cd from Apple’s store
      I got an xcloud for a month – could have used macincloud
   2. download High Sierra from the app store on the mac
   3. Create virtualbox image
      I Had to go for generic Mac OSX 64 bit, not the specific High Sierra one !!

VBoxManage modifyvm Sierra  --cpuidset 00000001 000306a9 00020800 80000201 178bfbff
