If you have updated to macOS 10.15.6 and work a lot with VMWare or VirtualBox you might have noticed that the Mac stumbles.
A bug in macOS 10.15.6 causes the whole virtualization solution to crash. As Darius found out at VMWare, the bug is in the sandbox of Apple’s operating system – so a fix from Apple is required.
Not only the products of VMWare seem to be affected, but also VirtualBox or for example Android emulators. So if you depend on these programs, you should stay with macOS 10.15.5 for now to have a working system. If you have already updated, it should help to reboot every few hours or put the virtual machine to sleep while it is not in use. The error seems to be related to how long it is used.
