Virtualbox 6 Macos



A couple of days ago all was working fine on my macOS 10.15.5 with VirtualBox 6.0.20.

VirtualBox 6.1.2 will not run Catalina 10.15.2 and later guests. Virtualbox 6.1.0 added support for booting APFS.Unfortunately there is a problem if you do not have 10.15.1 version of Install macOS Catalina.app. There is a bug in VirtualBox which is exposed by 10.15.2 and later versions of boot.efi.See this VirtualBox forum thread Catalina 10.15.2 does not start. When setup is finished, Windows 10 will be running in VirtualBox. When you’re finished, quit VirtualBox like any other application and Windows 10 will shut down. When you want to run Windows again in Mac OS X, just launch VirtualBox again, select your Windows 10 virtual machine, and click the “Start” button to boot Windows in the app. I am using VirtualBox 6.0.10 with Windows 10 host and macOS Mojave 10.14.5 guest. Installed Guest Additions successfully but still no clipboard and no shared.


I have Windows10 and Ubuntu. Today I needed Windows and when started I got the Windows 'blue' screen saying that some critical system files were not found and it tried to repair itself, for no avail.
Then I tried Ubuntu, which simply didn't start and its status turned to 'Aborted'
Making a long story short. I did a clean install of VirtualBox 6.1.10, used new and backed up VDI files for Windows and Linux. Created new VM re-using my VDI disks and tested, trying to look at the logs.

Open up your VirtualBox application and click New Click Expert Mode and select the following options then click Create. Type a suitable Virtual Machine Name. Virtual Machine Location (a. Introduction to Guest Additions. As mentioned in Section 1.2, “Some Terminology”, the Guest.


It simply getting aborted whatever I try. I have no idea of what's going on. Looking at my log at

I can run Ubuntu memory test from the Grub option and starting the VM in headless mode the status shows 'running' and that's all.
I hope someone can help me somehow.
Thanks in advance,
AlanOn my iMac 2017 5K, macOS Mojave, 10.14.510.14.4 (sorry), I successfully used VirtualBox 6.0.4 and wanted to update to VirtualBox 6.0.8. The update was apparently successful. Also the guest machines, Windows 7 and Windows XP ran well in the beginning. But later there were crashes of macOS, i.e. spontaneous restarts. Finally with broken machines, so my virtual machines didn't start anymore. So I uninstalled VirtualBox 6.0.8 with the uninstall tool and installed the old version. But the machines were broken. Finally the complete system was restored from backup. Now everything runs again.

Virtualbox 6 Macos Mojave

Sorry, I don't have any screenshots or logs.
And I'm terrified to try the update to VirtualBox 6.0.8 again.
Has anyone had similar experiences?
