25-minute update of macOS 11.2.1 (20D74) for my Z370 | 9600K | RX 580 build with OpenCore 0.6.6

Done multi restarts....no issues (other than usual it relocated my Apache config files to Users/Shared/Relocated Items).

Updated from 11.2 to 11.2.1
Clover 5129, and all most recent kexts.
Download, 15 minutes writing prebooter.
Three restarts, with a final 10 minute update phase.
All good!

After 3 reboots, still going strong on OC 0.6.5

A few (3) reboots and all is running well on OpenCore 0.6.5

Update doesn't appear to me. I tried with gibMacOS and no luck. Any tip to force the update?
Found the issue: SIP was the culprit here, reseting nvram does the magic.

Updated without issues, OC 0.6.6

Thanks!
