VirtualBox MAC OS For me many of the tutorials or iso's didn't work. The only method on VirtualBox is to get a .vmdk file with High Sierra and linking it as harddrive. (google, for example here  ) The image you can find online, will not run on a AMD processor. Also, enable USB3.0 else - your input devices will not be captured (like mouse and keyboard) Execute this command in a commandline, to fix the bootloop cd "%programfiles%\Oracle\VirtualBox\" VBoxManage.exe modifyvm "YouMacImageName" --cpuid-set 00000001 000106e5 00100800 0098e3fd bfebfbff VBoxManage setextradata "YouMacImageName" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "MacBookPro15,1" VBoxManage setextradata "YouMacImageName" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0" VBoxManage setextradata "YouMacImageName" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-551B86E5744E2388" VBoxManage setextradata "YouMacImageName" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" VBoxManage setextradata "YouMacImageName" "VBoxInternal/TM/TSCMode" "RealTSCOffset" Forums suggest this line, as well, but it causes my virtualbox to not boot VBoxManage setextradata "YouMacImageName" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1   Reach Client from Host (network) In order to connect to the virtual image, you have to add an adapter that is "host-only"   You can then start up your virtual machine and connect to it
