Setup Catalina 10.15.3

Notes:

Latest Version from the PPA

wget -q -O - http://download.virtualbox.org/virtualbox/debian/oracle_vbox_2016.asc | sudo apt-key add -

sudo sh -c 'echo "deb http://download.virtualbox.org/virtualbox/debian bionic non-free contrib" >> /etc/apt/sources.list.d/virtualbox.org.list'

Then you need to install the latest version with apt or the package manager.

sudo apt install virtualbox-6.1

You will need to manually download and install the extension pack.

There is no guest additions iso for the Mac guest.

something about licensing :)

Linux(kubuntu) Host

Windows Guest

MAC Guest

The other way of doing this with qemu is here.

Get Ready
  • There are very many ways to do this.
    1. This is mainly taken/borrowed/stolen from here.
  • First download the files

iso

  1. You can get this from many different places
  2. Take your chances all of them may be hacked in some way.

Boot Disk

  • Create and setup the virtualbox(before you start it)
    1. Run the following command.
      1. you can run them individually or with && inbetw3een them to make it faster.

VBoxManage modifyvm "Catalina" --cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff && VBoxManage setextradata "Catalina" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "iMac11,3" && VBoxManage setextradata "Catalina" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "1.0" && VBoxManage setextradata "Catalina" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Iloveapple" && VBoxManage setextradata "Catalina" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc" && VBoxManage setextradata "Catalina" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" 1

      • Who knows how many of these are really necessary

Changes

  • Set cpus to 2
    1. Any more is a waste. Some of the boot disks won't boot with 1
    2. VirtualBox can really only use 1
  • Video memory to at least 100mb
  • Ram to as much as 8 of 12.
    1. It will run and not freeze on 4 but you won't enjoy it.
  • Chipset to ICH9
    1. Some old tutorials want PIIX3
      1. NO!!!!!!
  • Enable I/O caching in Storage

Optional set display

  • Install the OS
  • Cleanup
    1. Remove the install iso
    2. Set the display to what you want
    3. Run the command: VBoxManage setextradata "Catalina" "VBoxInternal2/EfiGraphicsResolution" "1440x900"
  • Issues
    1. Cannot get icloud to work.
    2. We recommend nextcloud
