My FX-6300 hackintoshs can not update security update in Catalina 10.15.7(19H1708).
The error message and picture were posted here:
The same error presented as reboot loop during update of Big Sur or Monterey if legacy booted by Clover 5142/5143

Do you have SIP enabled and working NVRAM?

Do you have SIP enabled and working NVRAM?

SIP was disabled by 0xfef without native NVRAM in FX-6300 hackintosh.
What do you advise to fix this issue ?
I need enter F11 key to reset NVRAM before legacy boot by Clover.

Try this. Found on the German Hackintosh forum,

Then enter the following in the terminal:
diskutil mount /dev/disk0s1 and confirm with enter (change path to disk0s1 on your hard disks if different)
Then enter the following again
bless --mount /Volumes/EFI --setBoot and also confirm with enter.

Thanks for your kind help and I'll try it ASAP.
