Note: Big Sur guests are not supported due to the changes Apple made to the system volume. Additionally, because Apple has changed the anatomy of the installer application, AutoDMG cannot create a never-booted DMG for Big Sur or above. And finally, Apple Silicon doesn't even support virtualizing macOS. As a result, I won't be updating this script any longer. My heartfelt thanks to everyone who contributed code or issues. This community is amazing.
This script takes a never-booted DMG and converts it to a VMware Fusion VM.
The germ of this idea came about, as all good ideas, and germs, do: while drinking beer. Specifically, I was tossing back drinks and tossing around ideas with Gilbert Wilson, and he mentioned that he uses the VMware CLI tools to convert DMGs to VMDKs based on a blog post he'd read. Intrigued, I asked Gil to email me the specifics. After seeing how potentially cool this was, I wrapped it up in this here terribly illegible, queasingly unpythonic script.
Note: Big Sur guests are not supported. Because Apple has changed the anatomy of the installer application, AutoDMG most likely won't be able to create a never-booted DMG for Big Sur. And since that is a dependency for vfuse, we are currently out of luck.
Note: Version 3.0 requires python3. If you wish to continue using vfuse with Apple's system python2, you should use the vfuse 2.2.6 release. However, at some point in the not-too-distant future, Apple is going to remove python completely from macOS, and you'll need to roll your own python3 to be able to use vfuse.
Options for installing python3:
usage: vfuse [-h] [--version] [-i INPUT] [-o OUTPUT] [-n NAME] [-w HW_VERSION] [-m MEM_SIZE] [-s [SERIAL]] [-t TEMPLATE] [-e] [--disk_type DISK_TYPE] [-p PACKER] [-d D] [--hw-model HW_MODEL] [--board-id BOARD_ID] [--use-qemu [USE_QEMU]] [--recovery] [--snapshot] [--snapshot-name SNAPSHOT_NAME] [-c CHECKSUM] [--list-templates] [--list-cache] [--clear-cache] Create VM from source DMG. optional arguments: -h, --help show this help message and exit --version show the version number -i INPUT, --input INPUT /path/to/dmg -o OUTPUT, --output OUTPUT /path/to/output/dir -n NAME, --name NAME Use a custom name -w HW_VERSION, --hw-version HW_VERSION VMware hardware version -m MEM_SIZE, --mem-size MEM_SIZE Memory Size in MB -s [SERIAL], --serial [SERIAL] Custom Serial number -t TEMPLATE, --template TEMPLATE Use a template -e, --esx Create pre-allocated ESX-type VMDK -p PACKER, --packer PACKER Populate a packer template -d D Path to CD/DVD ISO path --hw-model HW_MODEL Custom hardware model --board-id BOARD_ID Custom hardware board id --use-qemu [USE_QEMU] Use qemu-img intead of the Fusion CLI tools [/path/to /qemu-img] --recovery Boot into Recovery HD --snapshot Create initial snapshot --snapshot-name SNAPSHOT_NAME Custom name for the initial snapshot -c CHECKSUM, --checksum CHECKSUM Generate checksum of a DMG --list-templates Return list of available templates --list-cache Return list of cached disk images --clear-cache Clear cached disk images
vfuse does not necessarily require sudo rights, but if you don't want to be prompted in the GUI for an admin password, run it with
sudo. (Escalated privileges is required to run the
vmware-vdiskmanager binary, which
The only required argument is
--input. Run thusly, it will create a vm called
macos-vm.vmwarevm in the current working directory:
/usr/local/vfuse/bin/vfuse -i /path/to/dmg
See the wiki for more on how to use
vfuse is meant to be used with never-booted disk images created with AutoDMG. Using
vfuse with a dmg created with Disk Utility is not something that has been tested, so you're on your own there. Likely, it's even more of a longshot with APFS.
