VirtualBuddy can virtualize macOS 12 and later on Apple Silicon, with the goal of offering features that are useful to developers who need to test their apps on multiple versions of macOS, especially betas.
- Apple Silicon Mac
- macOS 12.3 or later
- In order to install a version of macOS that's newer than the version running on the host (for example, macOS 13 VM in VirtualBuddy running on macOS 12), Xcode is required; Xcode beta may be required for installing macOS betas (
FB11061314
) - In order to install a Linux distro, macOS 13 is required
- Ability to boot any version of macOS 12 or macOS 13, including betas
- Ability to boot some ARM-based Linux distros (tested with Ubuntu Server and Ubuntu Desktop)
- Built-in installation wizard
- Select from a collection of restore images available on Apple's servers
- Install the latest stable version of macOS
- Local restore image IPSW file
- Custom restore image URL
- Install a Linux distro from a local .iso file
- Select from a collection of Linux distros
- Install Linux from URL
- Boot into recovery mode (in order to disable SIP, for example)
- Networking and file sharing support
- Clipboard sharing (without the need to be running macOS Ventura) (experimental ¹)
- Customize virtual machine hardware configuration
- Edit NVRAM variables
¹ To enable clipboard sharing, build the VirtualBuddyGuest
scheme, then copy the VirtualBuddyGuest
app to the virtual machine (through file sharing, for example) and run it. This will keep the clipboard in sync between the guest and host machines. The feature is experimental, so it might be buggy and it's definitely not secure.
Sometimes when trying things out in the OS installed in one of the virtual machines, things might break, requiring a full install of the guest operating system again, which is a pain.
Thanks to APFS cloning though, you can just duplicate a virtual machine within your library folder (using Command + D in Finder), and the copy will take almost no additional disk space. This way you can have a "clean" copy of your VM, do whatever you want with a duplicate of it, and then throw the copy away and re-duplicate the clean version if things break.
VirtualBuddy sets up its virtual machines to have the same screen resolution as the host's main screen. This is great if you want to use the VM in full screen and take advantage of the entire resolution of your Mac's display.
The default mode the VM OS selects for the display uses the native resolution that's available to it though, which can make things look really small. In order to address this, go into System Preferences > Displays within the guest operating system and choose a scaled resolution.
You can share folders from your Mac to the Virtual Machine and vice-versa using regular macOS file sharing that can be configured in System Preferences/Settings.
When both the Virtual Machine and the host are running macOS 13 or later, it's possible to share folders directly by configuring them in the VM settings within VirtualBuddy before booting up the VM.
To mount shared folders in the VM, run the following command in the VM's Terminal:
mkdir -p ~/Desktop/VirtualBuddyShared && mount -t virtiofs VirtualBuddyShared ~/Desktop/VirtualBuddyShared
Xcode 14.1 is required.
- Open the
VirtualBuddy/Config/Signing.xcconfig
file - Set the
VB_BUNDLE_ID_PREFIX
variable to something unique likecom.yourname.
- Select the VirtualBuddy project in the Xcode sidebar
- Under "Targets", select "VirtualBuddy"
- Go to the Signing & Capabilities tab and select your development team under Signing > Team
- Repeat the same process for the "VirtualBuddyGuest" target
- Build the
VirtualBuddy
scheme (the one that doesn't have(Managed)
in its name)
