Forcing a specific driver to load with brcmfx-driver= may help.

Mainly user-space patching has severely broke, meaning certain functionality may have broken.

Getting started with ACPI: Prebuilt SSDTs (opens new window).

Big Sur has added new requirements for ACPI, so you'll need to grab some new SSDTs:įor those who'd like precompiled files, see here: Reminder for AMD Users: Don't forget to update your kernel patches with those provided by AMD OS X, otherwise you'll be unable to boot Big Sur:įor X79, X99 and X299 users, pay close attention to the below.

Note: The about command will require you to include bit 0x2 in Misc -> Security -> ExposeSensitiveData, recommended values for ExposeSensitiveData is 0圆 which includes bits 0x2 and 0x4.

If you're unsure what version of OpenCore you're using, you can run the following in terminal:

MSI Navi users no longer require the ATY,rom/ -wegnoegpu patch to boot the installer.

This way, it will work in both Catalina and Big Sur so you can remove SATA-unsupported if you want.

We recommend setting the MinKernel value to 20.0.0 for the kext CtlnaAHCIPort.kext to avoid any potential conflicts.

You can find a sample kext here: Catalina's patched AppleAHCIPort.kext (opens new window)

A partial fix is to inject Catalina's version with any conflicting symbols being patched.

Due to the outright removal of the class, trying to spoof to another ID (generally done by SATA-unsupported.kext) can fail for many and create instability for others.

For some reason, Apple removed the AppleIntelPchSeriesAHCI class from AppleAHCIPort.kext.

Potential work-around is to inject a patched IO80211Family, see here for more details: IO80211 Patches (opens new window).
