The solution was to download the latest, Catalina-compatable VirtualBox installer.dmg (version 6.12 and up) and run VirtualBoxUninstall.tool. This failed, but prompted for extra permissions in System Preferences. In this video, I show you guys how to run macOS Catalina on Windows 10 using VirtualBox!I'm sorry in the long delay between this video and my last. Install VirtualBox on macOS Catalina When the VirtualBox dmg file imported to Virtual machine. Double-click and extract the setup file. While the setup wizard opened right-click and click on Open. Therefore, open VirtualBox and start the installation of macOS Catalina 10.15 on VirtualBox. After that, you run the installation just follow the steps to install properly macOS Catalina 10.15 on VirtualBox. Open VirtualBox and click on Created Virtual machine and click on the Start button.

I have a MacBook Air with MacOS Mojave 10.14.6.
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
• Create an ISO from the 10.15.2 Installer Application and boot from DVD/ISO Image

Run Mojave On Catalina Virtualbox

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?
