I am working on a very careful manual installation of OpenCore on a Mac Pro 5,1.

After reading many posts on many sites I now know that: "You can install Mojave natively on a Mac Pro 5,1"; "You cannot install Mojave natively on a Mac Pro 5,1".

I want to have the most recent version of the OS that can be natively installed on this machine, before I start the OpenCore process.

The Mac Pro has the following system specifications:
Model Name: Mac Pro
Model Identifier: MacPro5,1
Processor Name: 6-Core Intel Xeon
Processor Speed: 3.33 GHz
Number of Processors: 2
Total Number of Cores: 12
L2 Cache (per Core): 256 KB
L3 Cache (per Processor): 12 MB
Hyper-Threading Technology: Enabled
Memory: 24 GB
Boot ROM Version: 144.0.0.0.0
SMC Version (system): 1.39f5
SMC Version (processor tray): 1.39f5
Serial Number (system): XXXXXXXXXXX
Serial Number (processor tray): XXXXXXXXXXX
Hardware UUID: 6BA48E8D-904C-5691-8516-EC287C709611
Here is the information about the GPU:
Chipset Model: Radeon RX 580 Saphire
Type: GPU
Bus: PCIe
Slot: Slot-1
PCIe Lane Width: x16
VRAM (Total): 8 GB
Vendor: AMD (0x1002)
Device ID: 0x67df
Revision ID: 0x00e7
Metal: Supported, feature set macOS GPUFamily2 v1
I have a 2 Tb EVO 860 drive in a IcyDock holder that I can use for storage and experimentation by itself. The drive is blank right now.

I have 2 HP 24m displays with the following specifications:
Resolution: 1600 x 900
UI Looks like: 1600 x 900 @ 60 Hz
Framebuffer Depth: 30-Bit Color (ARGB2101010)
Display Serial Number: 1CR9130JW3
Main Display: Yes
Mirror: Off
Online: Yes
Rotation: Supported
Automatically Adjust Brightness: No
Note: I plan to use the second HP 24m as well.

Do I need to replace the Wifi and Bluetooth cards to start a manual (not OCLP) upgrade of the computer?

So, which answer is probably correct? "You can install Mojave natively"; "You cannot install Mojave", natively on this Mac Pro?

Thank you for your help.

No, you don't

That you can install Mojave on your MP51 as your firmware is already at the latest version, 144.0.0.0.0, and you have a Metal capable GPU.

It is often best to wrap such long datasets in spoilers

Use square brackets [ ] to wrap "Spoiler". I used braces to keep them from being active in my post.

BTW, delete these lines of confidential information from your post, the first in particular:
Serial Number (system): xxxx
Serial Number (processor tray): xxx
Hardware UUID: xxxx
 
No, you don't

OK. Thank you for the advice and information. Will do.
 
After much work, and Apple refusing to provide High Sierra, because it was "out of date/too old", and my computer refusing to install it (from a USB drive which has multiple operating systems) because the software was too old, I got the software put on, on a new drive.

I had to set the calendar back to 2016 on the Mac Pro, disconnect the ethernet connection to the internet, and then boot off the bootable USB flash drive. Once those things were done, the computer successfully installed High Sierra.

I can select High Sierra in the startup drive of the system preferences, and High Sierra boots properly; no boot picker on startup.

My plan is to do the same thing with Mojave, except to upgrade (rather than clean install) the High Sierra to Mojave, using the Mojave install from the bootable flash drive.

Does anyone see a problem(s) with this plan?
 
Just partitioned (using MacOS Extended Journaled and GUID Partition map) a 2 Tb EVO 860 SSD into two 1 Tb drives. I used Carbon Copy Cloner to clone my main Mojave drive (which had been bootable through a boot picker) onto one of the 1 Tb drives.

On the other I cloned my clean installation of Mojave upgrade from High Sierra to Mojave (no boot picker yet).

My plan is to experiment on the clone of the clean (no boot picker yet) Mojave. That way if something blows up, I still have the original drive.
 
I am needing to do this because I did have open core on my Mac and somehow lost access to the Catalina disk/partition after I worked with High Sierra extensively for a project that I had. At least that what I attribute to causing the problem. Plus I wanted to go through the setup again and learn more.
 
Another step is to find a good wired Apple, or Apple compatible, keyboard for this computer. I am happy using new or used.

Any suggestions, new or old?

Thanks.

P.S. I am currently using a Walmart onn brand wired keyboard and I wonder if the Alt switch really does the same thing as a real Option key on an Apple keyboard.

I am not sure if I missed anything. But if you want a good Apple keyboard, then why not just buy an Apple Keyboard?

For your info, the Magic keyboard can serve as a normal USB wired keyboard on the cMP when you connect the Lightning cable.

I'm thinking about the Magic keyboard. What is the lowest operating system that it supports?
 
Other World Computing has a nice selection of both Apple and Matias keyboards:

I have tried, and like the Matias keyboards. I especially like the mechanical ones and am thinking of getting a Matias Tactile.

Suppose OSX 10.11, but if you connect the USB cable, most likely it will work with any OS (apart from the special function keys may only can work as normal Fn keys).

Set the calendar back and upgraded from High Sierra to Mojave. It went well. Thanks!
In the future, if you still need to download Mac OS installers without having to change the date, this Macrumours thread indicates where to download previous or new OS installers, post #26

Download page

Alternately, I would also visit this blogsite by Mr Macintosh to download Mac OS installer. Mr Macintosh is also one of the best source on Opencore Legacy Patcher installations.
