Hackintosh Catalina Installation Guide for ASUS ROG STRIX Z390-I GAMING Motherboard

Perfect Vanilla Hackintosh with OpenCore bootloader like real mac.

OpenCore supports boot hotkeys, hold Option or ESC at startup to choose a boot device, Command+R to enter Recovery or Command+Option+P+R to reset NVRAM.

I used this guides as starting point:

Hardware

Gigabyte ASUS ROG STRIX Z390-I GAMING
Intel Core i5-8500T
2 x Kingston HyperX Predator 8GB DDR4 3000MHz
1 x GIGABYTE Radeon RX 580 GAMING 8GB
1 x Samsung 970 EVO Plus NVMe M.2 SSD 250 GB
1 x Broadcom BCM94350ZAE/DW1820A M.2 WiFi/ac and BT4LE (replaced on the motherboard)
- BCM4350 cards proved unreliable in terms of usage. Only some models work properly
- BCM94352Z/DW1560 is better

What works

Sleep / Wake
Power Nap (sleep with background operations such as Time Machine)
Audio (select internal speakers)
Ethernet
Bluetooth (lag when Wi-Fi is on)
Wi-Fi
15 USB port
AMD DRM for Music, Safari, TV, Plex, Prime, IQSV
