Re: How to change UUID on 10.9?
OK- fixed it. Used Terminal code:
/Applications/VirtualBox.app/Contents/Resources/VirtualBoxVM.app/Contents/MacOS/VBoxManage internalcommands sethduuid "/Users/MyName/Downloads/BMWCodingV3/BMWCoding.vmdk"
It assigned a new UUID, then I edited the .vbox file in TextEdit of the Hard Disks to be that number, then renamed the VM UUID within the same file by just changing one of the 4's to a 3. haha.
