Note: This is not to be taken as a complete list, but rather a list of known working cards that users have confirmed. If you know of a card that's supported by macOS, please reach out to me. Currently, the list is expanding, non-bootable cards will be listed as such. Known bootable cards will be listed as such. If no notes appear, it's because I haven't researched this yet. In the unlikeliest turn of events, Thunderbolt has landed on the cMac Pro PCIe Thunderbolt cards were exclusively for PCs that have compatible motherboards with specialized chipsets, generally requiring a pass-through jumper connection.
The original speculation started at eGPU. The only way currently to use a Thunderbolt 3 card is to cold-boot to Windows Initialize the Thunderbolt 3 card with the proper drivers installed, then reboot to Mac OS, where the Thunderbolt 3 card will remain Initialized. Also, only some Thunderbolt 3 devices work, such as audio interfaces.
Right now, it isn't very viable for all but tinkerers to purchase a Thunderbolt card, but this may change.

As notable progress unfolds, this section will be updated to reflect it. This isn't recommended as the computer will not wake from sleep and remains experimental. SATA2 still hasn't yet been fully saturated even by performant 3. The even the fastest current-gen 3. For those looking to sacrifice optical bays, OWC made a series of multi-mounts to go inside the dual 5.
New Mac users may not be aware, but built into macOS is an exceptionally powerful backup utility that not only keeps a backup of your entire boot drive and any selected external drives , it also has ability to undeleted files and resurrect old versions of files in addition to being able to restore your entire computer. For my fellow developers, it's essentially version control like Git but for your entire computer. I highly encourage all users to use Time Machine. Unless you do not care about the data on your Mac Pro, Time Machine is the single best upgrade you can add to your Mac.
Simply put, if there's any data you value on your computer, it is the best investment in this upgrade guide I can recommend. I've written a mini-guide, Making the most out of Time Machine. It covers recommended ignore paths, how to use Networked Drives, how to change the update intervals, and so forth.

Mechanical hard drives still a place in the SSD world thanks to their price-per-gigabyte. These are essentially a SATA 3 card with two mounting ports for 2. The 1. Mac Pro will have two M. Using M. The Mac Pro, being older doesn't quite have the options that the PC field has and does not support Bifurcation, the ability to split high speed PCIe port into two lower speed ports see the PCIe and You portion of this guide for more info.
Instead, the classic Mac Pros must use cards with controller chipsets specifically for computers that do not support bifurcation, hence more expensive. Also, important to note that some M.

The more expensive cards have switches that have a switch for PCIe 2. Lastly, M. Credit goes to MisterAndrew for doing the original compiling of this list here. However, due to the speed limitations, and age there aren't many models on the market. Clever users found workarounds. Then users found using firmware hacking. They could enable NVMe booting by using a firmware hack upgrade. See the entire thread here.
Notably, this firmware hack appears to work for 3. The latest Mac Pro 5. See below for more details.
A PCIe 3. Outside of PCIe 2. To summarize. There is a firmware update for the Evo Plus that fixes issues. While this guide will not explain the finer points of SSDs, it is important to understand that SSDs come in multiple variants based on its storage capacity. This is the top reason why HDD performance has radically increased over time. However, the same cannot be said for SSDs. Each storage unit in an SSD is represented as a cell. The first SSDs could store a single bit per cell, positive or negative.
This is referred to as a Single Layer Cell. The doubling of data per cell comes at a price: speed and reliability.

This additional data load per bit increases stress on each cell and takes more time to access the data, which is fractional, but 3 bits vs. Is it worse? Does it compare to a mechanical HDD? There are better sources on the internet, but it is somewhat speculative.

The best estimates are using Mean Time to Failure vs. Terabytes Written from large data centers, and we simply do not have the data. SSDs write data in data in units known as pages, and usually pages form a block. For an SSD to write data to a block, it first must delete the block reset the cell state before new data can be written, thus slowing down data writing speeds to previously used blocks. If only some of the pages are changing in a block, TRIM will shuffle current relevant data to a different block, freeing up the entire block to be written, instead of having to re-write the block.
I suggest searchstorage. In To enable a drive, open up a Terminal window and use the following command. You will be prompted for your password and given a warning. TRIM can be disabled at any time by using disable instead of enable. The Mac Pro 3.
Early 2009 Mac Pro, video card upgrade advice wanted.
Currently, the Mac Rumors has a works in progress guide. NVMe isn't natively bootable prior to the Note the following hack is no longer necessary for 5. Rather than re-outline them, the following links are useful. The Aura series is unlikely to be found in a cMac Pro setup as it'd require an external case. The Mac Pro's display limitations are a factor of graphics cards, what OS you are running, and whatever monitor you can afford or are willing to pay for. There are users with 5k displays and Mac Pros, including a user confirming two 5k displays working perfectly fine on his Mac Pro.
FRC works by parsing the bit color stream, and for colors that fall outside the 8-bit range, cycling between near shades of colors within the 8-bit spectrum. This visually creates a simulated bit experience and improves the perceived gamut. This is acceptable for many purposes, but film editors, colorists, and graphic designers may require the accuracy of true bit color.
These come with a much higher price tag. When buying a display, it's also important to consider color-space coverage. Color spaces for the unfamiliar are standards of color ranges that can be represented by a display, projector, or printer setup. Monitors may brag about its color space profile.
Not all color spaces are equal, some representing a lot fewer colors than others.

It severely suffers in the ability to represent shades of green and some blues. Adobe RGB is also similar to P3. Both represent a much wider gamut than sRGB. Selecting monitors based on color spaces can assist you in finding a display that's more suitable for photo editing, color grading, and capable of more range in the expression of color.
The Hz of a display measures how many times a second the screen is refreshed, which defines the maximum frames-per-second FPS a display can render. A Hz display can render a maximum of FPS. As computer hardware has improved, so have refresh rates. FreeSync and G-Sync are technologies that allow for variable refresh rates to improve the visual experience prevent effects like " tearing " , especially in the realm of gaming.
I can attest that enabling Freesync on a Freesync display caused the monitor to stop outputting video in Also, both tonymacx86 and MacRumors forum members have experienced the same sort of issues. The workaround is to disable the G-sync and Freesync if the monitor does not produce any video output. Forum members at MacRumors have confirmed that Hz 4k displays do work.
There's a minor caveat that flashed s and s booting with 60 Hz 4k displays will hang, thus must run at 30 Hz at the boot screen.
Later GPUs, do not have this issue. Not so fast. DVI has always been a bit of a hodge-podge standard, owing to the era it came from when displays were mostly analog. Both support 8k resolutions at their current iterations, as well as audio. The converters need additional power, thus usually have a USB connector to draw power.
