Okay, a quick one. I’ve updated my macbook now to Big Sur today. A lot of files have been copied and moved and written and so on – I think that update was something around 12 GB of files to download…
So my virtual windows machine won’t start. With a quick Google search I found some hints, that the kernel drivers will not load or something like that. A few posts below I read something about the System Protection of macOS and read on a bit.
Now to make things short: I restarted the macbook, went straight into recovery mode and fired up the terminal.
csrutil status told me, that my system was in an undefined state.
I’m not sure what I changed here on the last major macOS version but it printed
a few changes and something that I did not read completely. I just enabled the
protection system as suggested on the forums before and rebootet the system again.
To enable Apples protection system, type this command:
$ csrutil enable
After that, type
reboot and hit enter.
This fixed it for me and I am now able to run my virtual windows machine. But: I still cannot open my NFS shares on my Raspberry Pi yet.
