OpenCore Mac Pro 2008 3,1 Mojave

Mac Pro 3,1 2008 OpenCore full video acceleration with  Radeon GPU's in Mojave


The Mac Pro 3,1 from 2008 is perfectly capable of running Mojave DosDude1 but there are somethings you may want to have that OpenCore will provide.


Sometimes OpenCore default config will show odd things with the Processors this is purely cosmetic



Like a Boot Picker with out having a Mac flashed EFI card that shows native Apple Boot screens like when you press the ALT key on boot with a native Mac card or a stupidly expensive flashed card from Macvidcards?




You want the say RX 580 or an RX 570 in the system for video editing and  want to be able to utilize the full potential of the card's Hardware acceleration?

So lets put OpenCore on the system.

Well that is not so simple if you installed DosDude1's Mojave on an APFS drive.  With @Martin Lo's or  Man tat Lo  How to install "OpenCore for Mac Pro" package. 

You can use clover open the EFI drop all the files and bless the drive till the cows come home and it will never work.  Due to the helper partition and scripts that DosDude installs as helper for the system to use APFS.  

DON'T do this ... I am just telling you now.  Don't

So there is another way.  Hrutkay Mods has a video WATCH IT!!

Collin "DosDude" has a ROM Flash that will allow native support for APFS drives on the Mac Pro 3,1 2008 ***** WATCH THE VIDEO ALL OF IT FIRST!! 

How to Flash Your Unsupported Intel Chipset Mac for Native APFS Booting!


Okay, still DON'T DO THIS.. IF YOU PROCEED I CAN NOT HELP YOU YOU ARE ON YOUR OWN.

Once you have installed the APFS patch / rom flash you can boot to APFS drive YAY!!! But you can not just deleat the helper files for APFS that DosDude installed.  

You have to reboot from your DosDude Mojave patcher USB again.  

Re-install Mojave after that is done re-run the patcher tool from the USB patch for your system 3,1 making sure that the APFS helper is unchecked. 

Boot in to Mojave and open the EFI drive with clover, drop the Boot and OC folder in to the EFI drive.

Bless the system re-boot and voila you have a boot picker hadrware acceleration for you RX 580 and you are ready to rock.  

 

Need more detailed info.  Drop a comment and I will do a step by step.
