No, I don't use it for regular day-to-day use. I use this for dotfiles development, maintenance, and testing mostly.Īre you really running MacOS in VirtualBox? This installer and Base System will then be used to create a new VM and install MacOS 10.15.3 on it in a partially-automated fashion. A working boot.efi file will be injected into the installer and Base System. This project has scripts that will create a new MacOS 10.15.3 Installer and Base System images as well as an EFI Boot image. Additionally the 10.15.3 Base System and MacOS Installer app can be patched using an older boot.efi which reduces steps to install. Solution: In order to install MacOS 10.15.2+ you must boot using the boot.efi from a MacOS 10.15.1 (or older) installation or Base System. Problem: The boot.efi file from the MacOS 10.15.2+ installer and Base System will not boot on VirtualBox. (Scheduled to be fixed in the next maintenance release). In working through the issue of installing MacOS Catalina 10.15.3 on VirtualBox I (like many others) ran into a bug in VirtualBox that prevents MacOS 10.15.2+ installations from booting. As the state of the EFI issue evolves this project will be cleaned up and evolve as well. This project is a fragile work in progress process and hopefully most of it won't be needed once VirtualBox fixes the EFI boot issue. This project is a fork / merge / modification of the following projects: The process will partially-automate the MacOS Catalina 10.15.3 Install and requires some user interaction. This project will help you install MacOS Catalina 10.15.3 as a guest on VirtualBox (currently only tested on MacOS).
