An easy-to-follow step-by-step guide
Supporting the Mac Pro 3,1 / 4,1 / 5,1 EFI
The following document provides an easy to follow, step-by-step process for upgrading your Apple Mac Pro to include to support NVMe PCIe SSDs. Note: If you are running NVidia and AMD video cards at the same time, , shut down and reduce your installation to AMD or Nvidia cards.

In this step you are going to make a NEW EFI rom with DXEInject using the NVMe driver Apple provides for the MacPro 6,1. Copy and paste the following in to your open terminal window and press enter:
./DXEInject ./macPro2010-original.bin ./macPro-nvme.bin ./NVMe_DXE.ffs
If you did not get an error, as shown above, the process succeeded. You are almost done. One more page to go.
Enjoy NVMe hard disk support. You successfully added an upgrade to your Mac Pro that should have been provided by Apple. Really.. No excuse for this one.

The SMC is responsible for these and other low-level functions on Intel-based Mac computers:
x4 PCIe M.2 PCIe adapter
Supports 1 PCIe SSD
MacOS Boot drive support
Up to 1550 MB/sec*
Features to look for
integrated heathink
integrated fan (some reported to have longevity / noise issues)
PCIe 3.0 PLX Quad M.2 - Highpoint SSD7101-a
Supports 1 to 4 PCIe SSD
MacOS Boot drive support for 1 PCIe SSD up to 3250 MB/sec
Up to 6500 MB/sec* in Raid 0 with PCIe 2.0 x16 slot #2
Integrated heatsink / fan (slightly noticeable Higher pitch idle noise than cMP)
The table below details the reported maximum speeds of PCIe SSD’s in the Mac Pro 3,1 / 4,1 / 5,1 using standard x4 M.2 PCIe adapters and the Highpoint 7101-a PCIe 3.0 Quad M.2 adapter.
Mac Pro | Adapter | x4 | x16 boot | x16 modified |
3,1 | x4 M.2 | 750 MB/s | 750 MB/s | 1500 MB/s |
3,1 | x16 PCIe 2 Squid | 1550 MB/s | 1550 MB/s | 1550 MB/s |
3,1 | x16 PCIe 3 SSD7101 | 750 MB/s | 3250 MB/s | TBD |
4,1 / 5,1 | x4 M.2 | 1550 MB/s | 750 MB/s | 1500 MB/s |
4,1 / 5,1 | x16 PCIe 2 Squid | 1550 MB/s | 1550 MB/S | 6000 MB/s |
4,1 / 5,1 | x16 PCIe 3 SSD7101 | 1550 MB/s | 3250 MB/s | 6500 MB/s |
Managing Mac pro temps,
Buildup of residual heat in the silicon engages speed throttling to balance the heat by lowering performance. Using a M.2 SSD heatsink and increasing the speed of the PCIe BAY fan with Macs Fan Control, can help manage thermal throttling of NVMe disk operations.https://www.crystalidea.com/macs-fan-control/download

PCI Tools for MacOS w/DirectHW.kext
Unzips a folder structure of opt\pcitools\sbin
Drag and drop kext installation.
Follow these steps to disable SIP:
In finder, Launch Kext drop
In finder, Drag the DirectHW.kext from opt\pcitools\sbin and Drop it on Kext Drop and press install.
open a terminal window pointing towards opt-> pciutils -> sbin ( how to )
download updated PCI IDs
sudo nvram boot-args="debug=0x144"
sudo ./update-pciids

sudo ./fast.sh 00:7
Expected output
# Initial PCIe 1.0 x16

Failed speed change:
# Initial PCIe 1.0 x16
# Final PCIe 1.0 x16
Hopefully slot #2 should now be running at PCIe 2.0 - 5.0 GT/s. Note the PCI address of 00:7 is for slot #2 on a 2009 cMP. If you have the wrong address for the 2008, it can be looked up using the lspci to provide a very verbose list of PCIe devices and their current speed.
open a terminal window pointing towards opt-> pciutils -> sbin
To output a list of components on the PCIe BUS, type the following terminal command.
sudo ./lspci
The image below reflects the end of expected output from running lspci. Slots for the Mac Pro start at 01:00.0.
Let’s take a an up close look at the PCIe slots in the Mac Pro:
The Highpoint SSD7101-a starts at address 06:00.0.
We need to set the speed of the device at address 7:00.0
starts at 6:00.0 - this matches the set configuration
