I happened to download a new version today and noticed that there is a VirtualBox 7.0.2 download for 'Developer preview for macOS / Arm64 (M1/M2) hosts' on the virtualbox.org website. https://www.virtualbox.org/wiki/Downloads

I had some tasks fetched at around 09:00UTC 05Nov21 which failed with X509 errors - for example:

These ran for quite short times (200-300s).
but I have a task fetched at about 22:50UTC 05Nov21 which is still running now. I am hopeful the problem has been fixed.

Thanks. I will change my BOINC manager proxy setting to the machine IP address as it is a fixed value assigned by my router.

This seems to be related to macOS 11.16.x

I came across this thread on Ask Different https://apple.stackexchange.com/questions/408154/macos-big-sur-virtualbox-error-the-virtual-machine-has-terminated-unexpectedly-d with a similar 'VirtualBox Error the virtual machine has terminated unexpectedly during startup with exit code 1 (0x1)' as I had experienced. I'm testing out the suggested solution (run csrutil, uninstall and reinstall VirtualBox) and it seems to be hopeful. My single CMS task has been running for 55mins where it was stopping after 10s before.

Not sure how to troubleshoot CMS task errors like this https://lhcathome.cern.ch/lhcathome/result.php?resultid=331542649
which shows as 'Error while computing' in my task list.

I'm running BOINC Manager 7.16.19 and VirtualBox 6.1.28 on an Intel Mac Mini macOS 11.6.1
I think these errors started since I went from macOS 11.5.x to 11.6.x, but I have also been moving my BOINC Data folder to a different SSD (now back to its original SSD)

Thanks, I'll try these steps if it turns out not to be a server problem.

I'm running on a Mac Mini (macOS Big Sur 11.5.2) and recently had to rebuild my system disk and the disk where my home directory is located from a Time Machine backup. I also re-installed BOINC (v7.16.19), VirtualBox (6..1.26) and its corresponding Oracle VM VirtualBox Extension Pack. I'm not running a local proxy HTTP server.

My CMS tasks are all failing with 'Error while computing'.

My VMS console showed this (for a single task):
https://www.dropbox.com/s/0a791879nscyjo4/VMS%20console%202021-08-25%20at%2006.15.04.jpg?dl=0
The VMS log for the time of this failure is:
https://www.dropbox.com/s/mhv2ernacrqg04b/VBoxSVC.log.gz?dl=0

My computer is listed twice in my LHC@home 'computers on this account' page. Should I merge these entries?
