Basic info

This is the OpenCore 0.7.3 (V2) package specifically built for Mac Pro 5,1 to run Mojave (and newer macOS) to gain HWAccel support. But this package also includes lots of other functions that requested by other users. 

e.g. 
a) Boot screen (via GOP for unflashed card. Works better with AMD RX460 or higher)
b) Boot picker (only support EFI operating systems)
c) Firmware protection (e.g. to run UEFI Windows. BootROM version will be spoofed to 9144.0.7.3.1. This is normal, and safe for the cMP)
d) ability to watch DRM streaming content (only for AMD GPU, RX460 or higher. Mojave and later)
e) NVMe and SATA drives on PCIe card show up as internal
f) TRIM (regardless trimforce status)
g) Support for Apple USB SuperDrive
h) Enable Continuity
i) Ability to run non-GUI 32bit software in Catalina
j) Ability to run any natively supported ancient OSX with modern graphic card (e.g. Radeon VII in 10.6.8)
k) Ability to boot Catalina / Big Sur / Monterey and the associated Recovery Partition [SurPlus (credit to Syncretic) is included and enabled by default to fix the racing condition macOS 11.3 or later]
l) Possible to run 8x32GB RAM in macOS [WARNING: on the first time you enable this memory config, you may need to let the cMP keep rebooting itself for 45min or even longer before all 256GB RAM can work properly in macOS]
M) Enable HDMI Audio for some graphic cards (e.g. GTX680, disabled by default)

Installation / update

A) If this is your first time to install my OpenCore package, please perform a 3xNVRAM reset, then boot to recovery to disable SIP, then follow the steps in this video

B) For existing OpenCore users, you may follow the simple steps in this video to update OpenCore

For Big Sur only, if some ports on your graphic card are disabled, please follow the steps in this video to re-enable them.

For those who already have UEFI Windows installed, you may consider to install OpenCore onto the Windows drive's EFI partition. In order to do that, after mount the EFI partition, you should
1) rename the NO NAME partition to EFI
2) keep the Microsoft folder
3) replace the Boot folder
4) install the OC folder.
This will gives you better protection, and your cMP can never boot to the UEFI Windows without via OpenCore, which can corrupt the NVRAM and brick the logic board.


N.B. Every time you update the OpenCore package, the config will be reverted to default settings. NEVER use your old config for previous OpenCore in the new package. If you need to mod your config, you have to do this after EVERY OpenCore update manually.
