It includes fixes for USB 3.0 support, mouse and keyboard support, and other useful VirtualBox patches. Before creating the macOS virtual machine, you need to install the VirtualBox Extension Pack. How to Create a macOS Big Sur Virtual Machine With VirtualBox.
Virtualbox Os Free Space Temporarily
You also need ~20 GB disk space for the virtual machine, as well as ~18 GB free space temporarily for the creation of the install media.Create a macOS install ISO file for VirtualBox It's always a struggle to get macOS as a guest system running on macOS as the host system, but today was my lucky day and after several failures I managed to get it running! So here is how I did it.MacOS Sierra 10.12.6, VirtualBox 5.1.28 with installed VirtualBox Extension PackYou will need at least 4096 MB RAM of host memory, more is better. These can be found in out/darwin.x86/release/dist along with a small script (loadall.sh) to load.So I have a MacBook Pro running macOS Sierra (10.12) and I wanted to run a virtual machine (VM) of macOS High Sierra to try out the new operating system. Close VirtualBox, run Command Prompt as an administrator, and copy/paste the first line from the screen resolution code file.Running VirtualBox Load all the kernel extension modules. However, this can be changed using the macOS screen resolution code.
Open a Terminal window, create a "virtual USB flash drive"/disk image: The version of the "Install macOS High Sierra.app" has to be 13.0.66 or above. Apple made some changes to the previous released version, especially to the installer, which are important to get this VM running. Hint: if you have downloaded macOS High Sierra before the 5th of October, delete it and redownload it.
System -> Motherboard -> Boot Order: deactivate Floppy Virtual hard disk size: ~20 GB (an empty installation of macOS High Sierra takes about 11,4 GB) Version: Mac OS X (64-bit) or macOS 10.13 High Sierra (64-bit)

After the reboot, the VM will display an error message: "Boot Failed. The installer installs some files and after a while the machine will reboot automatically Choose your previously created virtual hard disk and finally start the installation with a click on "Install" Agree to the terms of the license agreement When the erase process is done, close Disk Utility Highlight "VBOX HARDDISK Me.", then click "Erase", choose a name for the virtual hard disk and click the "Erase" button to partition and format the virtual hard disk
You have to be very quick! If the machine is already displaying "Boot Failed. Now you have to be very fast: while the VM restarts, press the fn+F12 keys a few times, so that it gets into the VirtualBox boot manager. To do this, restart the machine (CMD+R will hard reset it, or, if the "Part 1"-Installer is already running, click on the Apple logo in the menu bar and choose "Restart"). So we have to do this manually. Why? VirtualBox doesn't recognize that there is a new disk, containing a second EFI, in which we need to boot into.
macOS High Sierra will then continue to install itself. Choose boot.efi, this will boot the machine into the "Part 2" installation process of macOS Go to "Boot from File" and hit Enter again. If you were fast enough, choose "Boot Maintenance Manager" and hit the Enter key.


What needs to change that it boots into the already installed Mac OS?Have you changed the boot order to HDD in the setting of the VM or have you removed the ISO from the virtual disc device?This was a very good tutorial, and you obviously took a lot of time composing it. After reboot the VM wants to start from installation again. I saw other people as the question but did not see an answer. One time I did take out the installer, but every time, I keep coming to the same problem and errors.Great article. I did initially reset the order for startup to put HDD in front of the CD drive that still has the ISO installer. This is third time going through the process.
But then it stopped, and the “Choose Language” window never came up.You can see an image of where it left me at I would really appreciate it if someone could guide me about how to make things work, so I can get Mojave working within a VirtualBox machine. I followed each of your steps, substituting my own filenames:Hdiutil create -o /tmp/Mojave -size 8G -layout SPUD -fs HFS+J -type SPARSEHdiutil attach /tmp/Mojave.sparseimage -noverify -mountpoint /Volumes/install_buildSudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia –volume /Volumes/install_buildHdiutil detach /Volumes/Install\ macOS\ MojaveHdiutil convert /tmp/Mojave.sparseimage -format UDTO -o /tmp/Mojave.isoMv /tmp/Mojave.iso.cdr ~/Desktop/Mojave.isoBryans-iMac:~ bryanhiggs$ hdiutil create -o /tmp/Mojave -size 8G -layout SPUD -fs HFS+J -type SPARSEBryans-iMac:~ bryanhiggs$ hdiutil attach /tmp/Mojave.sparseimage -noverify -mountpoint /Volumes/install_build/dev/disk4s2 Apple_HFS /Volumes/install_buildBryans-iMac:~ bryanhiggs$ sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia –volume /Volumes/install_buildTo continue we need to erase the volume at /Volumes/install_build.If you wish to continue type (Y) then press return:If you wish to continue type (Y) then press return: yCopying to disk: 0%… 10%… 20%… 30%… 40%… 50%… 60%… 100%Install media now available at “/Volumes/Install macOS Mojave”Bryans-iMac:~ bryanhiggs$ hdiutil detach /Volumes/Install\ macOS\ Mojave/Bryans-iMac:~ bryanhiggs$ hdiutil convert /tmp/Mojave.sparseimage -format UDTO -o /tmp/Mojave.isoBryans-iMac:~ bryanhiggs$ mv /tmp/Mojave.iso.cdr ~/Desktop/Mojave.isoBryans-iMac:~ bryanhiggs$ rm /tmp/Mojave.sparseimageI followed your steps for creating a new VirtualBox machine (the screens were slightly different, presumably because I am using a later version of VirtualBox (Version 6.0.14 r133895 (Qt5.6.3)) ), and I substituted my filenames, of course.However, when I started up the VirtualBox machine I had created, it showed some promise because it seemed to be executing a lot of commands.
