Before you begin, we strongly recommend performing a full backup of your existing system using Carbon Copy Cloner. By doing this, you can always go back to your working macOS Catalina installation.
Guide: Update Directly to macOS Big Sur
1. Update your existing bootloader. Bootloader update to OpenCore 0.6.3 or Clover Release v5.1 r5126 required for installation. For the purposes of this guide, we will reference Clover locations. Note: Clover requires proper Quirks config.plist additions. See here for details.
2. Open Clover configuration folder on the root of your system drive or EFI Partition using EFI Mounter v3. Copy VirtualSMC.kext and any other extra necessary kexts to /EFI/CLOVER/kexts/Other/. If you need kexts, download them here. If you need precompiled SSDTs, download them here.
3. Download Install macOS Big Sur Application from the Mac App Store. When complete, the app will open. Please note, the Application will disappear after use.
4. Choose system drive for install (Example: Macintosh HD). When complete, the computer will automatically reboot.
5. At Clover boot screen, choose Boot macOS Install option (Example: Boot macOS Install from Macintosh HD). Choosing your system drive will go back to your previous installation without updating.
6. Complete the installation process- the computer will automatically reboot a few times.
7. At Clover boot screen, choose Boot macOS option (Example: Boot macOS from Macintosh HD). The computer will then complete the update.
