If I want to move to Monterey, shall I do it through system preferences update like regularMacs?DO I need to updated bootloader or it was already updated with the new EFI folder I added. And I cant thank you enough!

Model Name: Mac mini Model Identifier: Macmini7,1 Processor Name: Quad-Core Intel Core i7 Processor Speed: 3.4 GHz

I generated new system serial number, SystemUUID that goes with MacMini 7,1

I did it . Update OK at least I managed to restart w/o a problem and I will keep using my old Big Sur.

I dont want to be too much where shall I find my SystemUUID. I cant believe myself I have been hackintoshing for many years and still no grasp of basics. I found ti but how to replace, shall I open the new EFI with configurator and just replace it?

Yes it must be

No I did not. I messed. I guess I am too old for this thing. Whenever I try to update I mess and try to remember what I needed to do and dig the internet and wait for rescue (you and other members generously provide which I am grateful) I still have the original installation USB somewhere I...

Well, I started with this, wanted to update bootloader first, I dont know what version it is but must be old as I havent updated for nearly a year. To updated it , I downloaded latest OC version and I opened my EFI folder and started to replace files Did BOOTx64.efi OpenCore.efi...

Hi everyone. I run Big Sur 11.6.1 (20G224) and want to move to Monterey. What's the safest and easiest way to upgrade? I can try to do a clean install but there is some stuff I have to reinstall.

I feel stupid, I should have checked them and send a message (if needed) afterwards. I fixed the BIOS settings and booted up. Thanks for your kind reply

I needed help again I changed the BIOS battery today as I did not have one last time but now I can't start Mac OS

It was not that bad. Having an installer USB was priceless.

So I need to repeat all steps from scratch. That's a pain but my own fault. Thank you for your swift reply.

It went OK, it is 11.6.1 (20G224) now. But there was a problem, when restarted the screen does not come back on 570's HDMI . I had to connect internal GC's DP to the monitor. I havent done restart yet with Big Sur, after I post this I will. Edit: It has restarted normal

I downloaded the one you posted n the original thread , so it must be 0.6.9 OC Should I upgrade OC and use System Preferences update ? PS I already updated the BIOS to 25

A quick question, I installed Catalina today with OC from scratch after Unlock CFG and Increase DVMT pre-allocation to 64MB" according to @trs96 's original golden built. Can I now just update from Catalina to Big Sur or I have to make a fresh installation (that I failed miserably last time)

Hi everyone, a happy festive seasons to you all. I messed my Optimac while trying to update to Big Sur and I had to start from beginning. I failed to install Big Sur and no matter I did and finally just installed Catalina which worked fine (used OC) and works fine except bluetooth. It is Wifi...
