Run Catalina On Virtualbox



I have a MacBook Air with MacOS Mojave 10.14.6.

The purpose of a creating a shared folder is to transfer documents between your Mac running Catalina (HOST) and the VirtualBox virtual machine (GUEST) running Mojave versions of Screenwriter 6.5 and/or Dramatica Story Expert 5.3. Once you follow these steps and set this up, you won't have to do this again. I use VirtualBox 6.1, but had the same problems with 6.0.14. I'm running a virtual machine with MacOS 10.15.1 without any problems. For me it is not possible to update the virtual machine to 10.15.2. I tried these things: Chose the update in System Preferences / Software Update; Download the 10.15.2 combo update and install that.

For the updates, after reboot and for the boot from ISO-disk, all activities on hard drive or DVD stop at the Apple Logo a second after boot.
Going to EFI and searching for the boot.efi in the macos_updates folder does not help. After failing, it is still possible to boot into the 10.15.1 version by manually selecting the correct entry in the Boot selection of EFI. Log files don't show anything.

Was anyone able to update to 10.15.2 or install a clean 10.15.2? Can someone confirm the problem?

This document will provide instructions on getting a macOS Catalina install working with Guest Additions on VirtaulBox 6.1.

Start by downloading a copy of the installer from the App Store. You will need a computer running macOS and you will need to convert the installer to an ISO. I will not be covering these steps here, but there are plenty tutorials online.

Installing VirtualBox

I’m hoping you already have this part covered and you are coming here only because you had issues getting macOS installed, but just in case, make sure the following packages are installed (Arch):

Creating the VM

Start by creating a new VM. Give it a name without spaces.

Give it enough memory so the install will run faster. We can change this later.

Select to create a new Virtual Hard Disk

Select VDI

Select fixed size

Give it a bare minimum of 25GB (I would advise on at least 50GB if you can spare the space)

Edit the machine, go into «System => Motherboard» and disable floppy boot and change the chipset to PIIX3

In the processor give more CPU if you can spare

In «Display => Screen» increase the video memory to 128MB and enable 3D acceleration

Enable USB 3.0

Note: if you can’t see USB 3.0 you might need to add your user to the vboxusers group

Insert the install ISO

Additional Configuration

Virtualbox

Now we need to run a few vboxmanage commands for additional settings. Either run the lines with vboxmanage from the script below (add your virtual machine name under $vm_name), or save the full script and run it.

Note: the default resolution is set to «1280x1024». You can change it in the last line of the update code. Make sure to keep it to “640x480, 800x600, 1280x1024, 1440x900, 1900x1200“

Installing macOS

We are now ready for the install. Start the machine and select you language.

Virtualbox

Select disk utility.

Select the VirtualBox hard disk and click on erase.

Give it a name, select the same options and click on erase. Close the disk utility when done.

Click on install macOS.

Continue with the install as you would until you are presented with the desktop.

Note that the installer will reboot once in the middle of the install.

Installing Guest Additions

We now need to get Guest Additions installed. Remove the install ISO and mount the guest additions CD. Open it with finder and run the VBoxDarwinAdditions.pkg

Install it as if you would install any other package.

Geekrar Install Catalina On Virtualbox

You will most likely get an error message that the install has failed.

Close everything, unmount the guest additions CD and open a terminal window (Command+Space, type terminal).

Now we need to restart the VM in recovery mode. Type in:

Once it has rebooted into recovery mode, on the top click on «Utilities => Termminal»

Can I Run Macos On Virtualbox

Type in the code below. This is to sign Oracle software as authorized. Then we disable recovery mode and restart the VM.

When the VM has rebooted you should have guest additions working. Remember that not everything works, but the features below should:

  • ~Drag and Drop~ Reported as not working (see comments)
