macOS guests on VirtualBox are generally incompatible with other CPU models. The script is designed for x86 CPU Mac hardware. Some features may behave unexpectedly, such as USB device support, audio support, FileVault boot password prompt support, and other features, including critical functionality. Further functioning order of VirtualBox or macOS is beyond the scope of this script. The scope of the script is completing a default macOS install process on VirtualBox on supported hardware. See the documentation command for further information. After the installation is complete, the storage size may be increased. The script by default assigns a target virtual disk storage size of 80GB, which is populated to about 25GB on the host on initial installation. These can be set in EFI and NVRAM by editing the script. ICloud, iMessage, and other connected Apple services require a valid device name and serial number, board ID and serial number, and other genuine (or genuine-like) Apple parameters. iCloud and iMessage connectivity and NVRAM The majority of the script is either documentation, comments, or actionable error messages, which should make the script straightforward to inspect and understand. Documentationĭocumentation can be viewed by executing the command. If you would like to become the maintainer of this repository, please see issue #645 - maintainer wanted. MacOS Catalina (10.15), Mojave (10.14), and High Sierra (10.13) currently supported. Should work on most modern Linux distros. Works on macOS, CentOS 7, and Windows on x86 CPUs with VT-x or AMD-V. Macos-guest-virtualbox.sh is a Bash script that creates a macOS virtual machine guest on VirtualBox with unmodified macOS installation files downloaded directly from Apple servers.Ī default install only requires the user to sit patiently and, less than ten times, press enter when prompted by the script, without interacting with the virtual machine. I use a cheap NVMe SSD in a 10Gbps USB-C enclosure-not this exact one, but one like it.Push-button installer of macOS on VirtualBox Any external SSD attached over a 5Gbps or 10Gbps USB connection or the Thunderbolt bus should feel fast enough for most things. Mac users with limited internal storage might want to change that to an external drive to save space, since the default disk size for new macOS VMs is 64GB. And more is better, especially if you'll also be running heavy apps like Xcode alongside (or inside) your VM.īy default, VirtualBuddy keeps all of its files (including VM disk images) in a folder at ~/Library/Application Support/VirtualBuddy. Personally, I wouldn't recommend trying to virtualize macOS on an Apple Silicon Mac with less than 16GB of RAM. But you'll be running two entirely separate OSes on the same computer, and that comes with RAM and storage requirements. VirtualBuddy and the Virtualization framework don't have hard-and-fast requirements aside from requiring an Apple Silicon chip for macOS-on-macOS virtualization. You'll also want to pay attention to the hardware requirements for virtualization. With the Xcode beta installed, everything works as intended (but if you can find a way to get this working without installing a 33GB app that takes an hour-plus to install, I'd love to know about it). When I've tried this without Xcode installed, macOS has tried (and failed) to download extra software to make it work-sort of like how macOS needs to download additional software the first time you use Rosetta. If you're looking to virtualize Ventura on top of Monterey, you'll want to install and run the beta version of Xcode 14 from Apple's developer site before you start. If you want to virtualize macOS Monterey on top of macOS Monterey, you won't have to download anything else.
