Description of problem

Before updating to QEMU 10.0, my OS X 10.8 installation has worked pretty clear, but after QEMU update, XNU kernel now throws divide error during the boot.

Steps to reproduce

1. Install OS X 10.8 on QEMU <10.0, for example 9.2.3.
2. Update QEMU to 10.0 version
3. Launch OS X

Additional information

Screenshot of the issue:

OpenCore config (not changed before update, so above suspicion): config.plist

Full OS X folder (without Installer.dmg): OS_X_10.8.zip

How I've done Installer.dmg:

1. Go here
2. xar -xf to .pkg
3. Show package contents to extracted .pkg
4. Here it is: InstallESD.dmg, which I've renamed to Installer.dmg
