[pre-release] macOS Big Sur


3,698 posts in this topic

Recommended Posts

I really don't see this big need for everyone to disable security features like SIP. These security features do not effect the installation nor use of macOS BigSur or any other version of macOS in anyway. I can understand if you need to overwrite a system file or something but after the fact, it should be re-enabled.

Hi @MorenoAv even you get green not will run Apple TV movies. It's a error in DSDT compilation that MaLD0n fix, and appears green, and run nice others thinks, except that apps that requires protect against screen recorder, for exemple. 

This error on DSDT cause red light.

@ham4ever, thanks a lot for sharing your EFI. @SavageAUS, I believe that I found the problem: I was not defining properly the device path for the WiFi card and the way it’s attached to the mobo is different as I had to install it in a PCI port in which I first installed a Startech PCI to PCIe adapter. I ran out of PCIe ports due to a USB 3.1 card that when installed disabled my PCIe x1 slots. This scenario works well in Catalina as the adapter is recognized OOB by macOS and the WiFi card was also recognized without major issues but with Big Sur everything changed. My only question is if I have to add device properties separately for both the adapter and the WiFi card. I attached the list of devices extracted from hackintool in Catalina.

pcidevices.txt

@ham4ever the WiFi issue was finally fixed with @MaLd0n assistance. In a nutshell, the AirportBrcmFixup kext was modified to remove the two new plugins, and in a DSDT @MaLd0n fixed the WiFi idk issue. I updated the config file removing from kernel section the reference to the two plugins and included the device properties based on the WiFi idk in DSDT. The only matter that I’m still curious is that even though the platform info section in the config file is properly completed based dortania guide for Hasswell, the About This Mac is showing in the serial number the following message: “To be filled by O.E.M.”. Does any of the hackintoshers know why the serial number is not displayed correctly. The serial number is the same one I have in macOS Catalina and has no issues. Big Sur is running from an externally enclosed SSD.

I have a question, is the control center lag normal in hackintosh?


I believe that has to do with your WiFi not properly working. E.g. on my late 2012 Mac Mini I had the same issue until I got Wifi working and I've seen people reporting the same issue on hackintoshes whom reported it as fixed once they've got proper Wifi configuration (kexts, DSDT patches etc).

Real macs have the same issue. Guess it has something to do with how Big Sur works, since it doesn't boot from the actual volume but rather a sealed snapshot.

Bingo. With APFS snapshots disabled, I can mount the Big_Sur volume from High Sierra and Catalina...

I don’t have Catalina installed anymore as I can’t get it to boot with my Big Sur EFI anymore. I’ll have to review the changes with an older EFI and see if I can get them both working again, as stable as big sur is it’s still beta and the next one may not install / upgrade then I’m screwed.

I've seen a few posts discussing the difficulty booting Catalina with Big Sur, I don't have the problem, as a matter of fact I moved Big Sur onto my main drive and have Catalina on an external drive. I did start off with BS on the external but swopped them around as I saw BS running stable even though it is still Beta. I have the one EFI Folder which is on the BS Partition that boots both as well as Windows.

[mention]eSaF [/mention] yeah I think I know what it may be from the KP I get. When I get a change I’ll try it out and see if I can get it installed again.

Have you tried repairing the disk in Big Sur?

For those interested it was NVMeFix that was causing a KP for Catalina for me. Removing that kext and updating config.plist with it removed has allowed catalina to boot and install.

Now I think the new plugins for AirportBrcmFixup are stopping Catalina booting. Does anyone know how to block them just on Catalina but allow them on Big Sur?

There is a new commit for AirportBcrmFixup 20 hours ago. Maybe it would be interesting to build new beta :) I don't know if the boot-args works with news plugins.

Have a look to the readme files for Big Sur.
