[Guide] Install/Restore BigSur with OpenCore

[gaule]

@MaLd0n 

Thanks for refinement to my DSDT. It's working fine under Big Sur but I've annoying problem. If I open Terminal for the first time, it works normal but when I quit and reopen Terminal, it behaves like TextEditor. I mean there's no way to type command. I also noticed that I can't shutdown the system and Control Setting hangs during 3 - 5 seconds. Any tips will be appreciated.

Thanks I used you EFI and it did the trick! I'm feeling the Mac is a bit too slow at startup than my previous EFI. Also the volume wifi toggles don't respond well, Is it because of Beta version of BIG SUR?? Its a bit laggy when I click the buttons. Catalina on the other side is a bit laggy but not as compared to BIG SUR.

One more question... Can I change the products name iMac Pro(2017) to something new. What should I do to change that in you EFI??

Can't I make it like MacPro the latest one? Thanks xD!!

One more thing mate!! I have Catalina and Big Sur on the same partition and when I try to partition down some space from the Catalina, I was able to do so. But the new created volume can't be added to Big Sur partition. Why??

It shows untitled and gives a message it would wipe everything off!! What Should I do?? I have tonnes of extra space on the other partition. Please help me with this too... Thanks

Can I change hard disk name from Test to Something else?? How will I do that?

You can do that by changing your SMBIOS (SystemProductName and other related variables, like SystemSerialNumber, MLB, BID, etc.) in your config.plist (use PlistEdit Pro and edit those keys in Root/PlatformInfo/Generic and Root/PlatformInfo/PlatformNVRAM). The correct values that refers to MacPro you can check on Clover Configurator (use it just to see the values that you'll replace in PlistEdit Pro). If u have no idea of how to do this, I suggest u read this guide: https://www.olarila.com/topic/8918-opencore-vanilla-guide-step-by-step-full-dsdt-patched-or-ssdt/

Thanks a lot! Big Sur is taking a hell lot of time! Booting time can be adjusted but after that it takes a lot to bring up the doc. then takes a whole bunch of time to respond and then it takes time to even open up finder, folders. But after a while everything becomes fast! Do you know what is the reason? Will it be the EFI i used the pre-made EFI from here. 

 

Can someone help with the booting and startup time. Anyone know the reason???

Did not understand you brother. Start a Fine tune means???

Does it mean I need to play around and make changes in the EFI?

COPY PASTING MY EXACT PROBLEM: [PLEASE HELP]  It would mean the World to me.

 

So I have installed Big Sur recently and it takes a hell lot of time to boot. It. takes a long time with the codes and the apple logo and the I get the lock-screen entering there sometimes I get to see the wallpaper or sometimes it's black. Then it takes a long time to bring up my folders and stuff. I try to go click about the mac, it never comes up. Then I will try to open the finder it too takes time. I would open safari or any app it takes a lot of time. But after all this is done and I have used the system for while then its superb fast. Apps open up so damn fast, Rendering, FCPX, Android Studio everything.

BUT why is it taking time at the start??? I used a pre made EFI that I got from a guide that helped me to install BIG SUR! Will that be the reason?? Can someone please help I'm stuck here. I don't know why this is happening.

Please don't tell me this is because of the BETA version as I had the same Issue with Sierra. And I have seen Big Sur booting soo quick in several systems. Please help if you know what to do...

Thanks XD

Hey!

 

I get after I start OC this message:

 

OCS: No schema for BlacklistAppleUpdate at 3 index, context <Security>!

 

And when I boot BigSur I get this error symbol

I Have done everything from your tutorial twice!

 

 But Thank everyone for the help!

 

EDIT: Added my EFI folder
