  7. Re: Mac Pro video card upgrade - UPDATE: SUCCESS - Ars Technica OpenForum;

The Mac Pro 3. Off-the-shelf NVidia cards also aren't supported in Mojave. Thus the Mac Pro 3. Notably, some security updates may fail at installing since they require updating the recovery partition manually. For many pros using legacy apps, High Sierra can wreak havoc on support. Note: for Mac Pro 5,1 users, this can interfere with later firmware updates, MacProUpgrade group members for instance, report that Updating to The Mac Pro 5. Updating requires pulling non-Metal accelerated GPUs they can be installed after the update and will still output video.

Currently, NVidia users are waiting for NVidia to release official drivers, but we're currently at statemate with NVidia suggesting the lack of driver updates is unsurprisingly Apple's fault. See Apple's official, Install macOS I signed it, but I can't say I'm hopeful.

Warning About Developer Previews in See the Firmware Upgrades section for more info. Apple in the past few years has moved to nagware for OS updates, often pestering users running non-compatible configurations to upgrade such as running a non-Mojave compatible GPU. You can disable the notifications following osxdaily's handy guide. I sourced the information from MacRumors , so all credit goes to the community there and forum member ActionableMango for compiling this list, this is truncated to the most important bits of information.

Also, 4. Also, go to the original thread to read up on 4. The process of delidding can be performed manually or bought pre-delidded. Most users elect to delid the CPUs themselves based on forums. Recently there's been interest in a few Mac Pro communities, but it's already been confirmed by a bold Mac Rumors poster. There's some misinformation on a few other sites like pindelski. Apple has updated Safari to prevent drive-by Javascript attacks. Using general safe browsing habits, makes it not very likely that this exploit will affect users despite very sensational headlines like Wired's Meltdown Redux: Intel flaw lets hackers siphon secrets from millions of PCs.

The only way to ensure total safety is to disable Hyper-Threading a significant performance hit , and Apple issued the article How to enable full mitigation for Microarchitectural Data Sampling MDS vulnerabilities. GPUs are probably the most annoying of the upgrades due to the required research yet one of the most commonly performed. This could change but has not yet. When I originally wrote my first Mac Pro Upgrade guide four years ago, readers found it surprising that one could use off-the-shelf Nvidia cards.

I tested a GeForce Hackintosh vs. GPUs are routinely one of the most common upgrades to Mac Pros. There are roughly three classes of GPUs. GPUs with Metal drivers for If this ever is sorted, we might have an aftermarket EFI bootscreen card. There's some overlap between the last two types of cards. This might sound undesirable but, with the gains of the NVidia cards, most users are willing to forgo the inconvenience, self-included. The most commonly flashable video cards are ones that have a Mac equivalent that was either sold by Apple as OEM or aftermarket, and the ROMs then were distributed on the open market, a few cards require physical modification.

Below are software-only flashable cards. I used for years an ATI Radeon With the NVidia video cards, even security updates can require a web driver update, meaning if you update, next boot will not output video until the driver has been updated. All the GTX series are supported by web drivers but are limited to However, neither AMD or NVidia cards will output video at the EFI boot screen, and video will not start until the drivers have loaded roughly right before the login screen.

This strikes me as predatory: OWC is actively abusing its market position as a trusted Mac upgrade vendor. The larger fan tends to block the adjacent PCI slot, making it hard to recommend for its minimal performance gains.

Recently in Mojave, updates have enabled hardware acceleration for video codecs on the RX You can read about it here and find full instructions to Activate AMD hardware acceleration. Thanks for Martin L. Many of the cards can be flashed to different bios. With the advent of Apple published an official list but did not list all compatible GPUs for Mojave. Currently, NVidia blames Apple for not approving its drivers for Mojave.

I've signed it, and I suggest others do too, even if non-NVidia users as options matter. I doubt it'll shift the tide, but a long-shot is better than no-shot. One of the rumors was that this was fought is over the Volta GPU drivers. This rumor gained a lot of traction since the last released version of the NVidia drivers, That said, without Mojave support for off-the-self NVidia cards, this severely limits the impact and do not currently have drivers for the macOS.

They will show up as a generic VGA output. NVidia driver installation is a little more tricky than one would expect, first off NVidia does not list what cards are currently supported on its web pages. Secondly, you need to download the correct version of the drivers for whatever version of Mac OS you have. TonyMacX86 forums do an excellent job of direct linking to the NVidia installers for driver version number by OS version. Currently, Seeing the above mess of information and the corresponding versions of drivers, Benjamin Dobell wrote a CLI utility to install the Mac NVidia drivers that work for your system, as described as "This script installs the best not necessarily the latest official NVidia web drivers for your system.

Several MacRumors forum members have found that Mac Pro 3. Many modern graphics cards have HDMI and thus capable of outputting audio. There's a very long thread of intrepid hackers at Mac Rumors. The cards do work but the turn-around times are long, communication infrequent and the prices are high, but they appear to be legitimate, with many testimonials floating around message boards from longtime members that they do indeed work as promised.

Note: Dave of MacVidCards notes he did contribute on previous AMD card hacks I'd rather not weigh too much on the ethics on it, but software developers do deserve compensation, and depending on the actual work performed on the EFI ROM, it may very well be truly custom. As of writing this, they are the only game in town when it comes to making the NVidia series cards Mac EFI compatible.

I suggest googling for them, and let you be the judge if its worth the cost. Update: Also, I have to note that, after reading the previous statement, Dave of MacVidCards reached out to me and also corrected on errors found on this page. So if nothing else, my experience with MacVidCards has been fair in my limited dealings with them considering my hesitation in recommending them. There isn't a "best card" for any computer, rather how much money you're willing to spend and if the money could be better spent elsewhere. This is an arbitrary metric as even a 3.

Commonly, forums and groups will mention "pairs well," or "bottleneck" but any high-end GPU will "pair well," the question is more about where a user can see more performance gains. I'd argue buying a 4. The next question is, do you want an EFI native card? There are few cards that support the EFI boot screen, and they are all older generation cards. Most users elect to hold onto an older card as a backup, for the EFI screen.

I personally have a GT in my Mac Pro at all times for this reason. Lastly, there's Mojave to contend with. This means its AMD or bust. Some readers have reported they are able to run high-power requirement GPUs off their internal power supply. These are likely required to power your GPU. Example, a GPU that has an 6 pin power port and an 8 pin power port would require one of each cable. I wrote two guides blog. The Mac Pros can support many more cards than listed here, but these are all common cards, NewerTech and Sonnet are reliable. Not all cards are equal, some are more performant, in the case of USB 3.

Also, some non-listed cards have issues. The only way to turn off my Mac Pro was to hold down the power key forcibly. I've elected not to include USB 2. 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 won't be fully saturated even by performant 3. For those looking to sacrifice ports, OWC made a series of multi-mounts to go inside the dual 5. These are essentially a SATA 3 card with two mounting ports for 2. The 1. However, due to the speed limitations, there aren't many models on the market, and the price per GB tends to be high as the industry has largely pivoted to NVMe.

Credit goes to MisterAndrew for doing the original compiling of this list here. 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. There is a firmware update for the Evo Plus that may fix issues. NVMe isn't natively bootable prior to the Note the following hack is no longer necessary, I'm leaving the information up for posterity and Mac Pro 3. 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. 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. 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. I've personally used several 4k displays with my Mac Pro at 60 Hz via DisplayPort with no issues beyond freesync. Forum members at MacRumors have confirmed that Hz 4k displays do work. The short answer is: yes, you can do it. TVs generally require some minor tweaking of the picture, such as enabling overscan correction in macOS.

Those looking to use a TV as a full-time monitor should keep a few things in mind. Not all TVs us Chroma subsampling. Video editors probably are familiar with this concept as not all cameras are but may not realize nor are all displays. Chroma subsampling refers to pixel clusters and data representation. The Human eye is much more receptive to changes in luminance than color. Thus, video data can be compressed easily by tracking clusters of chroma values and mapping them over pixels of chroma value.
