Updated OpenCore to 0.7.0, added support for macOS 12 Monterey Developer Beta
Changed default SIP mode to fix macOS system updates not appearing (I recommend running csrutil enable --no-internal from the Recovery's Terminal for existing installs, the key is the --no-internal flag)
The Algrey CPU topology patch has been replaced by OpenCore's new ProvideCurrentCpuInfo quirk
The +invtsc CPU flag is no longer required for the guest's clock to run at the right speed (but it doesn't hurt)
Note: After Monterey installation, when you initially get to the desktop, if you shutdown or reboot from this point macOS will get stuck in an infinite loop during boot. This is because the loginwindow process currently crashes when it is displayed. To avoid showing the loginwindow, before you reboot, either turn on FileVault encryption in Security settings, or enable automatic login for your account in the Users & Groups settings.
