Hey Martin

I'm not sure what you mean by "detached mode"? We're just using TeamViewer to remotely connect to the Mac.

The Windows 10-2021-09-22-14-43-05.log file ends prematurely and I don't see any indication of a crash. Please describe in some more detail what you mean by that.

Please reproduce the crash, look on the macOS host for a corresponding crash log, and additionally provide /Users/<username>/Library/VirtualBox/VBoxSVC.log.

Hey fth0

Okay, so the window with the VM is in focus. Either someone else connects to the Mac via TeamViewer or a new completely new connection is started. Then, what that user sees is: First the login-screen for the user, on which they are allowed to access. The password is typed in and the MacOS-Catalina login animation is displayed. Next, the window with the VM is visible for maybe 1 second before it just simply disappears. After that, the user is prompted with the "VirtualBox quit unexpectedly -crashlog-" and that's all that happens.

I have attached both files in a .zip-file, I hope this helps :)

Please add the macOS crash log to your Bugtracker ticket 20579.

Please try if entering the following command, while the VM is not running, makes a difference:

Code: Select all

VBoxManage setextradata "Windows 10" GUI/HidLedsSync 0

Hi fth0

Thank you so much, that command fixed it all! Wow, it was actually that easy...

I actually have one last question: what does that command do exactly? I need to document it, so we can explain it if we ever have to.

I really appreciate your help, have a wonderful day :D

See the VirtualBox User Manual: 9.25. Support for Keyboard Indicator Synchronization
