macOS Catalina for Asus Strix B450-I/F (OpenCore)

⚠️ OpenCore is still in beta. Please keep this in mind.

🛎 Join the Telegram Channel for notifications about updates.

Tested with macOS 10.15.4 SU1 with OpenCore 0.5.7 - any later versions of macOS and OpenCore have not yet been tested, so use them at your own risk. This configuration works with iCloud services, but it's strongly recommended to flush a new SMBIOS. Using the included one could result in a permanently banned Apple ID, which I can't be held responsible for.

System Specification

  • Motherboard: ASUS ROG Strix B450-I

    • Networking: Intel I211-AT
    • Audio: SupremeFX S1220A (ALC Layout 7)
    • Wireless: Realtek 8822BE (Stock)

Dual-booted with Windows 10. OpenCore installed on macOS SSD and set as primary boot device for OpenCanopy.

BIOS Settings

For the best results, load optimised defaults and change the following options;

  • SVM Mode -> Disabled (Enable after install)
  • SATA Mode -> AHCI
  • IOMMU -> Disabled
  • XHCI Handoff -> Enabled
  • Boot/CSM -> Disabled
  • Secure Boot -> Other OS

Ryzen G CPUs using integrated audio:

  • Core Performance Boost -> Disabled

These settings were tested with BIOS v2801 (24/09/2019) - use the latest available version of your BIOS to mitigate any issues (in general).

Known Issues

  • Internal WiFi & Bluetooth are not supported by macOS.

Solution: The internal wireless card can be replaced with a compatible one, such as the Dell DW1820A. I haven't tried this myself, but there are reports of it working...
