Running Mojave in VirtualBox under Big Sur

[ajanogueira]

I am running Big Sur on a MacBook Pro 2017 with 16Gb memory. Everytime I run the script when the Virtual Box is launched I allways get the same

I tried with other OSX images other then Mojave (all generated by installinstallmacos.py) I always get the same message. As you see from the log everything goes smothly
runMacOSVirtualbox.log

Hope you can help me sorting it out

Have you tried to delete all old files with clean and stash / stashvm? See make help. However, I'd assume something with using installinstallmacos.py is wrong. At the same time, the log doesn't look too bad...

I repeated tyhe whole process after running make clean and creating the Mojave install again.
The drive created in VirtualBox 6.1 boots properly but when I select Install MacOS I always get the message
"This copy of the Install macOS Mojave application is damaged, and can't be used to install macOS"

Any clues on what I should do? If needed I can shared the Installation disk with you (about 500 Mb).
Thanks

Instead of using the menu option "Install MacOS" I tried to launch the installer directly from the Terminal using
/Install macOS Mojave.app/Contents/MacOS/InstallAssistant

and the system installed properly
