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
The real easy way to run Catalina is to use the script to install Mojave on VirtualBox and then run it in VMWare and upgrade it to Catalina. 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. I was able to fix the UEFI problems as follows (credit to techrechard website):At UEFI prompt: Type exit You’ll be brought into an EFI text-mode GUI. Select Boot Maintenance Manager and click.

Install.log from a guest additions install on macOS 10.15 Catalina macOS-10-07-17-24-21.log (286.6 KB) - added by Kalak 18 months ago. Machine log from macOS host.
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
Virtualbox Catalina Vm
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
groupInsert the install ISO
Additional Configuration
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
How to scrape website data. ), 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.
Select disk utility.
Select the VirtualBox hard disk and click on erase.
Yes, FB changed something and now it doesn't work. A lot of ajax in the metadata file and no Titles. Update: Info is correct for January, 5h, 2021 I use DownAlbum for my FB group.

Give it a name, select the same options and click on erase. Close the disk utility when done.
Install Macos Catalina On Virtualbox Final Version
Click on install macOS.
Continue with the install as you would until you are presented with the desktop.
Install Os X Catalina On Virtualbox
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.
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»
Type in the code below. This is to sign Oracle software as authorized. Then we disable recovery mode and restart the VM.
Sync ios contacts to google account. When the VM has rebooted you should have guest additions working. Remember that not everything works, but the features below should:
- Copy/Paste
- ~Drag and Drop~ Reported as not working (see comments)
- VirtualBox Shared Folders
- Guest Control
