03 Create macOS virtual machines
Installing macOS in a VM can be a bit finicky, if you encounter problems, check the Discussions for solutions or ask for help there 🛟
quickget
automatically downloads a macOS recovery image and creates a virtual machine configuration.
quickget macos big-sur
quickemu --vm macos-big-sur.conf
macOS mojave
, catalina
, big-sur
, monterey
, ventura
and sonoma
are supported.
- Use cursor keys and enter key to select the macOS Base System
- From macOS Utilities
- Click Disk Utility and Continue
- Select
QEMU HARDDISK Media
(~103.08GB) from the list (on Big Sur and above useApple Inc. VirtIO Block Device
) and click Erase. - Enter a
Name:
for the disk - If you are installing macOS Mojave or later (Catalina, Big Sur, Monterey, Ventura and Sonoma), choose any of the APFS options as the filesystem. MacOS Extended may not work.
- Select
- Click Erase.
- Click Done.
- Close Disk Utility
- Click Disk Utility and Continue
- From macOS Utilities
- Click Reinstall macOS and Continue
- Complete the installation as you normally would.
- On the first reboot use cursor keys and enter key to select macOS Installer
- On the subsequent reboots use cursor keys and enter key to select the disk you named
- Once you have finished installing macOS you will be presented with an the out-of-the-box first-start wizard to configure various options and set up your username and password
- OPTIONAL: After you have concluded the out-of-the-box wizard, you
may want to enable the TRIM feature that the computer industry
created for SSD disks. This feature in our macOS installation will
allow QuickEmu to compact (shrink) your macOS disk image whenever
you delete files inside the Virtual Machine. Without this step your
macOS disk image will only ever get larger and will not shrink even
when you delete lots of data inside macOS.
- To enable TRIM, open the Terminal application and type the following command followed by pressing enter to tell macos to use the TRIM command on the hard disk when files are deleted:
sudo trimforce enable
You will be prompted to enter your account's password to gain the privilege needed. Once you've entered your password and pressed enter the command will request confirmation in the form of two questions that require you to type y (for a "yes" response) followed by enter to confirm.
If you press enter without first typing y the system will consider that a negative response as though you said "no":
IMPORTANT NOTICE: This tool force-enables TRIM for all relevant attached devices, even though such devices may not have been validated for data integrity while using TRIM. Use of this tool to enable TRIM may result in unintended data loss or data corruption. It should not be used in a commercial operating environment or with important data. Before using this tool, you should back up all of your data and regularly back up data while TRIM is enabled. This tool is provided on an "as is" basis. APPLE MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF NON-INFRINGEMENT, MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, REGARDING THIS TOOL OR ITS USE ALONE OR IN COMBINATION WITH YOUR DEVICES, SYSTEMS, OR SERVICES. BY USING THIS TOOL TO ENABLE TRIM, YOU AGREE THAT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, USE OF THE TOOL IS AT YOUR SOLE RISK AND THAT THE ENTIRE RISK AS TO SATISFACTORY QUALITY, PERFORMANCE, ACCURACY AND EFFORT IS WITH YOU.
Are you sure you with to proceed (y/N)?
And a second confirmation once you've confirmed the previous one:
Your system will immediately reboot when this is complete.
Is this OK (y/N)?
As the last message states, your system will automatically reboot as soon as the command completes.
The default macOS configuration looks like this:
guest_os="macos"
img="macos-big-sur/RecoveryImage.img"
disk_img="macos-big-sur/disk.qcow2"
macos_release="big-sur"
-
guest_os="macos"
instructs Quickemu to optimise for macOS. -
macos_release="big-sur"
instructs Quickemu to optimise for a particular macOS release.- For example VirtIO Network and Memory Ballooning are available in Big Sur and newer, but not previous releases.
- And VirtIO Block Media (disks) are supported/stable in Catalina and newer.
There are some considerations when running macOS via Quickemu.
- Supported macOS releases:
- Mojave
- Catalina
- Big Sur
- Monterey
- Ventura
- Sonoma
-
quickemu
will automatically download the required OpenCore bootloader and OVMF firmware from OSX-KVM. - Optimised by default, but no GPU acceleration is available.
- Host CPU vendor is detected and guest CPU is optimised accordingly.
- VirtIO Block Media is used for the system disk where supported.
-
VirtIO
usb-tablet
is used for the mouse. - VirtIO Network (
virtio-net
) is supported and enabled on macOS Big Sur and newer, but earlier releases usevmxnet3
. - VirtIO Memory Ballooning is supported and enabled on macOS Big Sur and newer but disabled for other support macOS releases.
- USB host and SPICE pass-through is:
- UHCI (USB 2.0) on macOS Catalina and earlier.
- XHCI (USB 3.0) on macOS Big Sur and newer.
- Display resolution can be changed via
quickemu
using--width
and--height
command line arguments. -
Full Duplex audio requires VoodooHDA OC or pass-through a USB audio-device to the macOS guest VM.
- NOTE! Gatekeeper and System Integrity Protection (SIP) need to be disabled to install VoodooHDA OC
- File sharing between guest and host is available via virtio-9p and SPICE webdavd.
- Copy/paste via SPICE agent is not available on macOS.
If you see "Your device or computer could not be verified" when you try to login to the App Store, make sure that your wired ethernet device is en0
. Use ifconfig
in a terminal to verify this.
If the wired ethernet device is not en0
, then then go to System Preferences -> Network, delete all the network devices and apply the
changes. Next, open a terminal and run the following:
sudo rm /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
Now reboot, and the App Store should work.
