How to Prepare for Big Sur

[sqig]

Hello, I have atempted up update from system definition 14.1 to 17.1. I used the guide in the OP and then pasted my old Serial number , Board serial number and System UUID into the Clover configurator Sbios page. Iam signed out of the apple ID. When I restart I still have iMac 27inch Late 2013 in my about this mac window. The rest of the infomation seems correct. How do I fix this ?
I now have the option to update to Big Sur in Software update.
Thank you

Reboot clear your NVRAM and see if that fixes it!

@scottkendall, thank you for your help.
In the end I changed to Opencore 0.6.3 and made a new iMac 17.1 serial.etc.
I was then able to install Big Sur.
Im impressed with OpenCore so far.

Oh my mistake I just assumed you were using OC already. OC is really the way to go for Big Sur, since clover actually just uses OC to boot the OS.

I had been using Clover since probably High Sierra and just recently switched to OpenCore 0.6.3 for Big Sur. I'm telling you, OpenCore is the way to go! I have one of the older Z270 motherboards and everything just works with OC/Big Sur (sleep, wake, sound, etc.) with the help of Lilu, AppleALC, WhateverGreen, IntelMausi, and VirtualSMC of course. I have never had any macOS installation that went this smoothly.

Can you send me a copy of your EFI folder for the Z270 board. I've been trying to get my OC config.plist to work with my GA-Z270x-UD5 board

I looked at my config.plist in Clover Configurator and saw that the SmUUID field was actually blank. But I have iMessage, handoff, dam, etc., all working fine....

Looking in the System Report, I do see a Hardware UUID value. Is this the same as SmUUID? It does have the same format aaaaaaaa-bbbb-cccc-dddd-eeeeeeeeeeeeeeee.

BTW: I do have a CustomUUID, and it *does not* match the Hardware UUID reported by the system. And if I ask Clover Configurator to "get it from system" it returns the Hardware UUID reported by the System Report. It is a wonder that iMessage ever worked.

Thanks

Having the same issues, with some exceptions. Changed system ID to 17,1 and ported my serials etc., tried deleting the NVRAM in my Clover EFI folder and I still see iMac 14,2 indicated in "About This Mac". That said, selecting System Report does show 17,1 indicated. Any idea how to get the "About This Mac" splash screen to correctly show what shows up in the System Report?

Someone else posted about this issue only I think there problem was reversed. In their case they had an old board ID for 14,1, with a 17,1 serial. In your case it sounds like you are using a 14,1 serial I would guess that to fix about Mac you would need to update to a 17,1 serial. However, as far as I understand it the stuff listed in about Mac is cosmetic.
