Hey gang,

Any advice on trying to do the latest security update on Catalina?

I download, restart, and it just doesn't take! OC Picker only shows my main boot drive.
Very strange because I've done plenty of updates this way with no issues...

Please advise!

EDIT:

Temporarily disabling SIP by changing csr-active-config to 67000000 worked!

I've said the same thing too, now shopping for the Xeon 3rd gen. :lol:
I’ve only seen some low profile reviews for them, some weird benchmarks showing pretty poor single threaded performance. Did you spot some more comprehensive stuff? Thanks.

Ha Ha! It happened due to the computer starts from CCC disk's EFI with the unchanged config.plist.... gone into Bios and set the proper start disk. and it is ok now.

Thanks! Just read through, I used the older version of Propertree to do the snap shot. Hence the problem. Everything works fine now.

I wonder if @rustEswan or someone else with an Asus Prime X299- A II would be so kind to share their OC 0.7.3 config.plist? I'm trying to update OC from 0.6.8 to 0.7.3 and having one hell of a hard time getting it to work. Keep getting weird "borked" error messages on startup despite me trying to update my new config.plist. to match the old one as closely as possible. Thanks!
