Hi,
since some weeks I struggle with lots of computation errors for LHC@home with CMS and Theory tasks. I've updated Virtual Box to latest version (7.1.6 r167084 (Qt6.5.3)) but it didn't solve it. Is there something I have to do with Vbox or is a plain installation sufficient?
I use Mac Powerbooks (Sequoia 15.3 and Monterey 12.7.6) with BOINC 8.0.2. On both Mac's I have the same behavior.
Have you any idea what I can do?
Thanks in advance, Dirk

Do you have Hypervisor enabled?

Must be off.

Hmm, where or what is Hypervisor? I've heard about HyperV with Windows, but on Mac? Or is it a config in Vbox?

The problem seems to be caused by vboxwrapper v26208 deployed Jan.16.
The developer(s) are working on a fix. The problem does not appear with Linux and Windows OS.
