The Mojave installer first will update the boot rom to (144.0.0.0.0). Here the installer will tell you what needs to be done first. Run the installer and follow on screen instruction.*(In this guide Sapphire Radeon Pulse RX 580 8gb GDDR5 is being used, however other mentioned cards will work fine too.) The Process: SAPPHIRE Radeon PULSE RX 580 8GB GDDR5*.MSI Gaming Radeon RX 560 128-bit 4GB GDRR5.We are assuming you are using one of these. Mojave requires a Metal Supported Graphic card.Check the boot rom version see if it matches with something similar to this (00).Firmware updates won’t work if your startup disk is a RAID drive, so use an onboard SATA.Make sure file vault is disabled ( Here’s How).Before you begin please make sure of the following. This is a step by step guide on how to go about updating your Mac Pro 5.1 to Mojave 10.14.6 form High Sierra 10.13.6.

There are threads on about which NVME drives and adapter cards work. If you do go with a PCIe NVME solution, understand that you will only be able to use High Sierra or later because modern NVME drives (512byte blocks) only work in High Sierra or later. A PCIe NVME SSD will blow the doors off of a SATA SSD, but it requires the ROM update first.īTW, once you get the boot rom up to 140.0.0.0 or later, you can still use High Sierra. Even if you don't stay on Mojave, it will get you the updated boot ROM, and that is key to putting in a fast SSD. I would first go with a Mojave/Metal capable GPU, so that you can then upgrade to Mojave. The most cpu intensive task I give mine is recompressing video, and that is only a few times a week. Most day to day tasks don't use multiple cores, games rarely use more than 4 cores even today. If, on the other hand, you are gaming, or just doing occasional tasks above, then a dual CPU will get you pretty much nothing but a nice score to look at.

If you make a living editing video or doing a lot of 3D, photoshop, video ripping or other professional work, then a dual CPU would be worth the cost. It really depends on what you plan to do with the machine.
