I installed a Sapphire RX 580 yesterday and today I found that I can no longer boot into a separate drive, in fact I get no boot screen at all... I will do a restart and hold option key, Mac just sits there, is it a power issue? Using 2x 6 pin to 8 pin, as far as I know it should be fine.
Thanks in advance

Thanks Lou, I will look into this today...
EFI Mod for the RX 580
Forget that, it's not public, only MacVidCards offers it and the price is high.

Look at OpenCore. This is the thread:

So far I am not finding any exact info on "EFI Mod" No one is explaining exactly what this is. only talking about that they did it. Is it Flashing firmware on the board or is it a separate install...
will continue to look.

I am reading up on this now, Wow this seems a little more involved than I am intellectually prepared for.
I am not an IT professional, I saw some videos on Opencore on Ytube, looks easy but the reading material suggest I need to code.... this is over my head.

It's up to you, there are two options only. Learn how to install OpenCore, it's easy to follow the instructions I linked, or send the card to MacVidCards to be modded and flashed, pay $150+ for the service and wait a month…

Look, all these videos are made from that tutorial. That thread consolidates all the work from multiple people here since OC inception.

Btw, no video will have up to date instructions, OC is a moving target with new releases once a month that changes things.

I read that moving target comment in some other article, my only reference to the video was if it was that simple.
I am reading the link info you sent and learning the process. I am actually finding out a lot of useful info...
I just ran across information about being able to boot 10.6.4 with BootROM 144.0.0.0.0 which is kinda useful as I may be able to migrate or reinstall my current version of Lightwave 3D onto 10.7.5...
I have a bootrom MP51.0089.B00 so I am almost there...
would like to contact you further if I have any question ... if this is ok?

The first step is to upgrade your BootROM, read the first post of the thread below:


The second one is to be sure that you have a Westmere Xeon on your Mac Pro: E56xx, L56xx, X56xx, W36xx. While OpenCore works with older Nehalem Xeons, you won't have access to one of the best resources, VMM spoofing and native software updates.

If you have any doubts about OpenCore install, please ask on the OC thread, there are lots of people that can help you there.

Thanks for the info, I will read that thread again as there are some things I am unclear on specifically for me...
but this is where my Machine is at right now:
High Sierra 10.13.6
2.88 W3530
bootroom MP51.0089.B00
Sapphire RX580
SMC Version (system): 1.39f11
SMC Version (processor tray): 1.39f11

I am not interested in Catalina, just Mojave, and from what I understand,
I can just load Mojave on a disk GUID APFS ready disk, let Mojave flash it to 144.0.0.0.0
then install Opencore via the steps in your tute... Yes?

Yes.

For Catalina, you need a newer Xeon.

2 things to note:
1. You will not be able to boot into 10.6 or 10.7 with the RX580, it will not be recognised (or is this fixed with OpenCore....?).
2. Any version of Lightwave up to and including V2015 will not work properly in Mojave, a lot of the icons are garbled, this problem was fixed in LW2018 but not for earlier versions.
LW will work fine in High Sierra.

NewTek wants me to upgrade to 2020, I have the trial version loaded on High Sierra now, but I don't have $700 to plunk down on Lightwave after trial is over... I 've been using Lightwave since Inspire 3D in 1999 my latest version is 11.6.3 been running this on my MP1,1 for the last decade or so... too bad. The goal here is to get the boot screen running so I can install windows 7 or 8, then run Lightwave 11.6.3 on a Windows platform (never done that).
There is a reason for all of this, see what Lightwave is making me go through...lol

Ok so the installation of Mojave failed, the installer wouldnt shut down to do the firmware update...
I figured I would turn off things I didn't need running to help the install and I found a hidden drive on the machine "InstallESD" there are a few packages inside "Core, Embeddedosfirmware firmwareupdate, secureboot osinstall"
do you know what these are and should I delete , or eject the drive

Don't mess with the installer. Re-read the first post of the thread below and find what is your problem.

If you don't find anything on the notes, start with a clean install of 10.13.6 on a new SATA drive and remove everything else besides the Apple OEM GPU, you don't need to start from 10.12.6 like the "If nothing above works for you, try this:" says since you already have MP51.0089.B00, but use the same instructions to simplify your Mac Pro. After a clean install of 10.13.6 on a SATA drive, replace the GPU, download full MAS installer for 10.14.6 again and try to upgrade the BootROM.

** Success**
I made a new High Sierra install on a new drive, booted into it... the way it loaded up gave me a string feeling of optimism I was getting a good vibe.
so.. I downloaded Mojave right there and installed it over the new High Sierra... boot Rom success, now I am on 144.0.0.0.0 ....
Ok so I will re read the instructions on installing Opencore... wish me luck.
Thanks Alex

You definitely can't use LW 11.6.3 then in MacOS.
As I said a lot of the icons won't display in Mojave, so you will have to run in Windows, unfortunately.

Alex I have a few question,
I installed OC and it works perfectly with one exception, My Windows install is not recognized by OC.
In the OC thread "Startergo" explained what the issue was he said the formatting of the drive in hybrid MBR is unreadable. So I deleted the Windows partition and will install windows on a separate drive like I intended.
However what format will OC recognize my Windows install?
Thanks for the help

OpenCore only supports UEFI Windows installs and you need to use OpenCore ProtectSecureBoot. Read about it on the OpenCore thread.
