Ubuntu image for virtualbox mac full#
You can run as many virtual machines on your mac as you want, as long as you've paid for the OS on your mac, which you can't buy separately anymore (making any restrictions on licenses a full ban on macOS VMs, which nobody wants). The last I heard about the macos situation is that virtualisation of macOS is allowed as long as you do it on Apple hardware that you have a license to run macOS on. You're right that you can only run one instance of a given Windows product code on a machine for long-time use, though. Option (2) only works on Apple hardware, and so by using option (2) Apple's license condition, of only virtualising macOS on Apple hardware, is automatically enforced.Ĭonsidering that VirtualBox is from Oracle, and as well as open source, they also sell it as a commercial product, you can understand why Oracle's lawyers want option (2).ĪFAIK you can use Windows unlicensed as long as you activate it after evaluation.
Option (2) is a lot of extra complexity compared to option (1), but has the advantage of being legally much cleaner. VirtualBox already has a bunch of kexts needed to provide various features, and so this is just a bit more code in one of those kexts. Apple doesn't supply a public API to retrieve this value, so VirtualBox has some code which runs inside a macOS kernel extension, and directly uses the SMC hardware registers to request it. Obviously method (2) only works if your host is a Mac. When enabled, VirtualBox retrieves the value from the SMC of your Mac.
(2) Ensure the "GetKeyFromRealSMC" boolean config parameter is enabled (not sure if it is turned on by default or not). (1) You supply this value in the "DeviceKey" config parameter VirtualBox supports two methods of operation:
