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 ID: 51501 · Reply Quote

Do you have Hypervisor enabled? 2025-02-06 14:43:51 (595): WARNING: Communication with VM Hypervisor failed. Must be off. ID: 51502 · Reply Quote

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. ID: 51504 · Reply Quote
