Hello

I made an upgrade to Virtual Box Version 6.1.36 r152435 (Qt5.6.3)
After then an upgrade to MOINC Manager 7.20.2
I'm only doing ATLAS Simulation.
So the new downloaded tasks will lead to a calculation error after 9s.

What can I do?

Using iMAC 27" 2020 with MacOS 12.5

Anwendung ATLAS Simulation 2.00 (vbox64_mt_mcore_atlas)

There are not many active Apple experts around here.
If you don't get a quick answer you may try the main BOINC forum:
https://boinc.berkeley.edu/forum_index.php

It looks like something got wrong during your upgrades.
A reboot sometimes solves problems regarding missing kernel modules like:

00:00:00.154497 nspr-2   SUP: Couldn't find any matches. The kernel module is probably not loaded.
00:00:00.154603 nspr-2   SUP: Couldn't find any matches. The kernel module is probably not loaded.

Thank's for the reply.
I restarted and it didn't help. Same error.
I'll try in BOINC forum. If I get help I will provide the answer here again.

Everything is working again today.

First I deleted BOINC and VirtualBox. Installed new with different VirtualBox versions .32, .34 and .36. Nothing helped.
I removed all folders with data inside from BOINC and ATLAS workload.
No solution to my problem.
So I decided to leave BOINC shut down and wait. A few times I started it and the workload was closed with calculation error.

Today I saw a new update for MAC 12.5.1 (Security fixes) and the MAC had to restart.
As BOINC started with startup I tried new workload. And voila it works again with no problems. Actually the first task has finished 5% and still counting.
