Even this VM exhibits the memory allocation, while endlessly displaying at the "No bootable medium found" message, albeit at a much slower rate of 4 KB per second (still more than enough for debugging )). This VM contains no storage controller, no graphics controller, no everything I could get rid of. They have no known workaround at the moment, other than not using macOS Catalina 10.15.6 or running VMs only shortly.Īfter reproducing the crash, I've stripped down a VM to virtually nothing (see attached Empty.vbox). A VMware Fusion developer (Darius, dariusd) has "narrowed down the problem to a regression in the kext (or one of its related components)" and "filed a comprehensive report with Apple".Terminating a VM doesn't free the kernel memory, so the memory usage is accumulating until the next macOS reboot.

When the kernel memory is exhausted, macOS randomly terminates processes but cannot recover, eventually leading to crashes in a random process. This can be easily observed using sudo zprint -d. Fix macOS not booting with VMware boot loop rebooting OS X OSPY 6.64K subscribers Subscribe 42K views 3 years ago macOS Tutorials macOS not booting with VMware Workstation Player boot loop. In the macOS kernel memory zone named "kalloc.32", continuously allocation of memory takes place, with a rate of about 1GB per hour.

The VirtualBox version probably doesn't matter (e.g. Due to the issues users of VMware Fusion or Virtualbox had been advised to refrain from updating to macOS 10.15.6 (which came out in mid July), as this version of Apple’s operating system caused.

The crashes occur only on macOS Catalina 10.15.6, not on macOS Catalina 10.15.5.

The crashes have already been analyzed to some degree in a VirtualBox forum thread ( ) and in a VMware Fusion forum thread ( ). When a VirtualBox VM (or a VMware Fusion VM) has been running on a macOS Catalina 10.15.6 host for a few hours, the host OS crashes.
