Yes. The original purpose of Martin Lo's OpenCore was to enable hardware encoding/decoding on Mojave.

Yes, provided you have an AMD GPU, Polaris or newer architecture.

Were you previously running Monterey with a different GPU or are you upgrading to Monterey for the first time?

I was running Monterey with Rx580, after a swap of graphics cards. I could not boot back to Monterey, I initially thought I knocked the NVMe on the next lane. However, two weeks later tonight, I had tried numerous methods to reinstall Monterey but nothing, always stuck at 1/4 of the Apple loading screen. I'm trying to install Catalina now :)

@@terrenterren4856 I haven’t had any such problems with mine. I also used an RX 580 to get to Monterey and then just swapped the GPUs and no problem. Is the W5700 known to work in a different machine? Could it have a modified VBIOS? I had that problem with my RX 580 initially and had to get the original VBIOS from TechPowerUp then flash it in Windows. After that it works fine in macOS.

@@terrenterren4856 Don’t put anything into the USB c port on startup. Use one of the mini DisplayPorts for your display.

Thanks for your reply Douglas, no, nothing at the USB-C port. The funny thing is I can use the w5700 with Mojave OS - with limited functions. So far, no luck with Monterey, nor Big Sur or Catalina. Perhaps something about the graphics Card. Its a new HP reference W5700. Considering it works natively with Mojave, it really should with the Monterey. I'm seriously scratching my head over this.

Works great EXCEPT that when the Mac boots with anything plugged into the USB C, I get no display. Once booted the port works fine. I have a Sandisk Extreme 1050 MB/s external SSD. In this port it runs just under 1,000 MB/s. It's the fastest port on the Mac by far, much faster then my older USB 3.0 card.

@@douglas_edward Ok thanks do you need any pixlas mode and Ava you tried it under Ventura or Sonoma with OCLP 1.5 Thanks

@@2HLPUBLISHINGRECORDSKevinClark no Pixlas mod. It needs 205 watts which is fine to power from the backplane and slot as long as you install bridge cables so the power draw from the two backplane mini 6 pins is balanced. No go on Ventura or Sonoma. The Navi drivers in those OSs require the CPUs have AVX2 instruction sets. The classic Mac Pro CPUs don’t. Unless OCLP patches the graphics drivers in the future, Monterey is the last OS for this GPU.

@@douglas_edward Ok great Thanks

Did you enable gop or is it a flashed one

I didn't actually show plugging in the cables, as I thought talking about the devices and setup would be more interesting to someone doing this. The connections are: 1) Plug the optical audio cable into the Digital to Analog Converter from the Apple TV's optical audio out. 2) Plug the RCA cables from the DAC into the stereo receiver's aux. inputs. Set the receiver input to Aux.

If you already have OCLP installed, then you only need update OCLP and use Software Update in Settings to update to the latest OS. Make sure your GPU is supported in Sonoma, though (Navi I and Navi II are not). I use a Navi I Radeon Pro W5700 in my Mac Pro, so I am staying on Monterey.

@@douglas_edward Hi, thanks for taking the time to respond. My GPU is a NVIDIA GeForce GTX 680 4 GB (flashed). What you say about updating sounds almost too good to be true - if I hadn't seen your demonstration. I think it would be wise for me to stay on Monterey. When you say 'Update in Settings', do you mean that I should allow the OS (Monterey) to carry out the update? The whole process used to be so tricky. I use a 4k BenQ monitor and it doesn't show the Apple boot screen even though it is flashed and works with other monitors - something about the drivers according to the people who flashed the GPU. Apparently, OCLP now shows a boot screen. Still can't fathom how easy you made it all look.

No I haven’t tried 2 cards.

The ability to cast your apple devices to other hardware. Its not special

App support is fantastic, it supports 4K HDR, Dolby whatever etc, it is quick and intuitive to use. The competition is just not there at all. Chromecast Ultra is somewhat comparable but they’re right to still call that a Chromecast. It is just not as good.

Nobody mentions it does lossless audio wirelessly?

AirPlay is most definitely lossy.

The lossy vs. lossless discussion is interesting. I noted in the video that my use of Bluetooth with the same stereo sounded flat and lifeless while AirPlay sounds full and rich. I suspect that I have older Bluetooth transmitting equipment is the problem. However, I had understood that AirPlay was compressed but lossless, using Apple's Lossless Audio Codec. A quick Google search shows conflicting information, but it appears that the original AirPlay standard, as supported by this Apple TV, is lossless, while the newer AirPlay 2 standard will transmit lossy compressed audio sometimes. FYI this article from Cambridge Audio www.cambridgeaudio.com/usa/en/blog/difference-between-airplay-bluetooth

You may be looking at current 4K Apple TVs. This is the 2nd Gen Apple TV from 2010. They’re long out of production but very available on eBay.

It goes over your home network (WiFi and or LAN).

Really just two ways of doing it. I had a Bluetooth receiver on the stereo but had problems with signal strength even across the room. Walking between the transmitting device and the receiver made it cut out. WiFi is strong throughout the house, so the transmitter and receiver don't even have to be close. Also, the sound is full and rich via AirPlay. I've just never got Bluetooth to sound good. It's lifeless and flat, probably because I am transmitting with older BT equipment. Bluetooth is also finicky with pairing. AirPlay never requires leaving the player app to go to settings, turn Bluetooth off and back on to try to get it to pair, then back to the player app to play.

@saltysourdough Well said!

I own 7 airport express they are the best solution for me. Legacy WiFi without privacy issues and AirPlay all over the house with synced playback.

Yep I love the air port express’s

I never understood why they discontinued this extremely useful product

Thanks for the info, i guess we just gonna stick with monterey for now !

I have same issues with anything above Monterey

I don't really think Martin Lo's OpenCore package or OpenCore Legacy Patcher will make a difference. What version of macOS are you running?

@@douglas_edward Monterey

I don't believe there is a way to install any macOS Mojave or higher without a Metal supported GPU card installed. Once the OS is installed would then work with the card removed? I don't know.

Before I answer, which macOS are you running?

@@douglas_edward Right now I’m running Mojave . No boot screen . I bought the computer 3 weeks ago as is.

The RX6600 is a great card, and flashing it is a one-time deal. Once done you have a card that can be used in the Mac Pro and transported to a Windows PC. Don't you know someone with a gaming PC? I used my son's to flash an RX 6600 XT and then an RX 6800. The company I work for has some older workstation PCs in reserve for "just in case". They would have lent me one with no hard drive for a weekend so I could have used it to flash a GPU.

@@douglas_edward I am just now getting into tinkering with computers and I don't have a group of friends who have a PC, I am already looking for an inexpensive pc to do the flashing on the RX6600 but I didn't want to go through the trouble if, for example, the w5700 would give me close to the performance of the RX6600.

@@iM-mf1ke I think the W5700 or RX 5700 XT would perform close to the RX 6600.

For now I am stuck at Monterey. Ventura and Sonoma GPU drivers require AVX2 CPU instructions, which no classic Mac Pros can have. OCLP will need to patch the GPU drivers for Navi. All of the Apple computers that shipped with Navi GPUs had AVX2 processors, so very few of us (classic Mac Pro users) need this patch. I hope they will patch it, but we aren't a high priority.

As I replied to your comment on the power draw video, the Navi and Navi 2 cards are not supported past macOS Monterey in the 5,1.

The RX 6800 XT is a Navi 2 architecture GPU. The driver in macOS Sonoma for Navi and Navi 2 requires AVX2 in the processor. No processor supported in the classic Mac Pro has AVX2. OpenCore Legacy patcher has not yet patched the GPU drivers for Navi or Navi2 in Ventura or Monterey. The last OS that doesn't require AVX2 is Monterey. SO, that GPU cannot be used in macOS beyond Monterey.

rx5000 macos 10.15 amd up

Hello @RichieKeane, I ran the RX 6800 in the 5,1 for nearly a year. Then, I bought an HP Z440 workstation to run some comparisons. The RX 6800 has been in the Z440 since. I never once had a problem with powering it from the backplane mini 6 pin connectors. I did install an EVGA Powerlink to make sure power draw was balanced. There is a video about that on my channel.

That wall paper comes with Big Sur. Since I had installed Big Sur and upgraded to Monterey, the Big Sur wallpapers stay there to use.

Maybe you're using the tool from post 887? This is the Mac version of the tool. Syncretic later followed with a Windows version in post 909 forums.macrumors.com/threads/amd-radeon-rx-6800-xt-6900-xt-for-macos.2262295/post-31045379.

Seems I've read about others having a slow boot time with OCLP. I haven't experienced that. Monterey boot is about a minute.

No, the card doesn't provide a boot screen in the Mac Pro. I get around this by using the boot screen OpenCore provides. I did also install EnableGOP on my Mac Pro, which enables the original Apple boot screen with a non-Mac card kzbin.info/www/bejne/gpynnWmCiNZmba8si=v58EhejBnKSn-_0B.

Sure. It looks like these came with Big Sur, from a little Googling. I don't know if you have to actually install Big Sur and then upgrade to Monterey to get them or if they will come in with a fresh install of Monterey. To get to them, right click o the desktop, then pick Change Desktop Background. Under the Apple folder there is a Desktop Pictures folder. In that folder they're under Dynamic Desktop.

Short answer, no. The native graphics acceleration drivers in Ventura and Sonoma require AVX2 instructions in the CPU. classic Mac Pro processors don't have AVX2 instruction set. OpenCore Legacy Patcher has patches for Ventura and Sonoma, but not Navi or Navi 2. For this reason, I am holding at Monterey.

Thank you so much

I have only the standard OpenCore Legacy Patcher installed, no mods to the Config.plist. It may have the Boot-Arg but I didn’t add it.

and with Martin Lo Opencore 097 package? @@douglas_edward

No, the 5xxx Radeons don’t need Syncretic’s patch like the RX 6xxxs do.

need flash for boot screen or we can enable GOP to get it @@douglas_edward

The W5700 is faster than the RX 580 Sapphire pulse 8 Go but does it work with OCLP and Ventura and Sonoma are you under Monterey @@douglas_edward

I've added links to the description.

​@@douglas_edwardThanks!

btw i noticed a little bit of performance lag when I use the basic 2x 6Pin PCIE cables. With a Pixlasmod I gained around 5-7% more performance, I don't know why

Does this card have to be flashed to work with the Mac Pro 5,1? I was debating about the w5700 and the rx6800 .
