Hi everyone,
first, huge thanks to people making possible to keep our old 10+ yo macs "up to date"
Feels great to have big sur on the cheesegrater.
Legacy mac pro 5,1 owner here, and cannot quite say that update has been smooth.
Anyway, i managed to have hardware acceleration on RT 5700 XT, which is already great.
Don't know if i'm at the right place for assistance, but here it is :
For now, i have 3 problems :
- black output on display port for 27' cinema display (from RT 5700 XT) - second screen works great though
- 5 min boot time, due to (3 times): IOKit Daemon (kernelmanagerd) stall[0], (60s): ‘IOHIDInterface’ (from verbose)
- mac sees update, but refused to even download it (see attached pictures) and make an error.
Update is available (strange double version number though)
Download seems to stop after few seconds
then makes an error - roughly translates to "download failed, check your internet connection"
Runnin low on solutions for these, i'll be glad to bring anything you could ask to help me

Hi, I am having a problem installing Catalina after successfully installing OpenCore 0.6.9.
When I am trying to install Catalina it goes through the first part fine and everything looks ok but when it goes to the restart it starts back up in Mojave.
Any ideas what I am doing wrong?
Thanks,
Chris

Hello, I understand this is a primarily MacPro4,1/5,1 thread though was curious if anyone had any insight into possible work arounds to the UGA setup of the MacPro3,1.
Recently picked up a machine to mess with however I’ve been unsuccessful getting UEFI output on my PC based GT 710 with GOP support, even with miscellaneous quirks in OpenCore such as UGA to GOP conversion with GopPassThrough as well as the Nvidia rom quirks such as ForgeUefiSupport and ReloadOptionRoms. GPU does boot fine into the OS, simply UEFI and kernel space output is missing. Discussed with vit9696 before and he didn’t have any ideas to try.
Has anyone been able to get a similar setup working? If not, are there any threads regarding where to find an Apple VBIOS (rather not have to flash, though have an SPI flasher in my desk to easily swap ROMs if needed)

GT 710 should technically work with ForgeUefiSupport and ReloadOptionRoms.
Can you try the MyBootMgr process linked in my signature?
This will set RefindPlus up to do what ForgeUefiSupport and ReloadOptionRoms do and the GOP bootscreen will propagate to OpenCore when chain loaded (even without those two quirks). This is for cMP3,1 or any other cMP.
If this doesn't work, then something's wrong with the GPU unit you have as the GT 710 has been tested with this setup.
I have GT-710 and I have updated the GOP with this tool and I have a boot screen with OC.

TL;DR: MacPro3,1 requires GopPassthrough for Apple based VBIOS that don't support GOP, however is not required for PC based GPUs that do support GOP.

Well, something odd there as this didn't affect @amstel78 when he raised the issue that led to implementation of GopPassThru:

Hello, so on my adventures of the MacPro3,1 I've gotten pretty far. However seem to have hit another road block. I wanted to try and see if I could get my RX5700XT working in this old guy.
Catalina boots perfectly fine once MouSSE is enabled to work around the SSE4,2 requirement of the AMD drivers, however Big Sur is the OS I hit a snag. Once userspace and graphics kick in, I just receive a black screen.
I am able to connect over SMB to access the drives but VNC fails. Additionally tried OpcodeEmu in case perhaps the Navi 10 drivers now require AVX but that didn't help.
Anyone here try a Navi 10 based card (ie. RX5500, RX5600, RX5700) in a MacPro3,1? I know they're extremely overkill but would like to get a Metal AMD GPU I have locally to work as I fear Kepler support will be dropped in macOS 12

I guess most are not bothering to try such on cMP3,1.
I suppose some might have such in their 4,1 or 5,1 that they can swap in for testing.
dont forget the need to make a power mod for some of those big GPUs.
the limit on the letter is still 75 Watt for a 6 Pin power connector. Real world is about 100 Watt till emergency cutoff.
8 pin is 150 Watt, so combining 2 x 6 to 1 x 8 is ok.
2 x 8 so is critical, 1 x 6 and 1 x 8 combined could fit depending of the power draw.
Pixla Mod is doable on a MP 3,1 too.
hi, I´ve got a big problem with my Mac Pro 5.1, GeForce GTX 770, 32G ram, I managed to install Mojave with my new GPU on my principal drive, then I have used opencore legacy to install Big sur on a second drive, unfortunately it was the 11.3 with many boots problems and dual monitor not well handled, I managed to make everything work but after the last reboot it’s stay stuck on the progress bar on any partition I’ve got, even my principal drive with Mojave gets stuck, I can’t do anything, recovery mode gets stucked too, BigSur installer too... any clue ? Thank you
Reboot with the Option key down and select the Mojave drive from the menu before the OC selection screen.
Then install Big Sur 11.2.3
Then install Big Sur 11.2.3

Is adding this key as a device property on the GPU's path all that is needed to inject the framebuffer?
Thanks
Has anyone tried installing 11.3 or x.4 on a SATA SSD? I keep reading about PCIe, but I mean worst case I just put my NVME in a nice Icy Box Server Caddy and inside that an SATA SSD to NVME adapter.
Would still end up speedy enough for me…

Unfortunately, this doesn't work in general. The issue is apparently related to PCIe devices but not caused by them.
Yes, but bear in mind that the port mapping on at least 1 output may be screwed. The ports can be remapped through SSDT, but I am not sure how to do it in the config file. @cdf may know how. You can record the port mapping from a regular IOregistry entry when booting natively and assign it in SSDT. When I have time I may play around with it and show an example.
This would be really interesting to use VBIOS versions expecting an DP connected internal LCD on LVDS based systems like the iMac10,1 and before. Can this really work out? Or do I only see what I would like to be true here?
This has been tested. It doesn't avoid the issue in general. There is, however, great variability from machine to machine for no clear reason, so you can always try your luck. See this thread for the latest on the issue:
Mac OS 11.3 has broken support for older Mac Pros
macOS Big Sur 11.3 Beta 3 has broken Mac Pro's early-2009 to mid-2012 ability to boot reliably into macOS. It's still possible to boot 11.3/11.4, but the process requires multiple restarts and a connection has been made between PCIe devices, especially storage related devices and USB controller...

Thanks for getting back. I also saw someone on reddit who had success by downloading and attempting to install 11.3, but then used the 11.2.3 Installer Pkg from Apple directly and that somehow ended up installing 11.3, maybe it spoofed the system into believing that the current os update snapshot is for 11.2.3 to then allow the 11.3 snapshot to process and not panic.This has been tested.

It makes sense especially in the context of Apple wanting to lock our old Mac Pros out of the ecosystem.
I will try this later.
This don't exist at all, only SATA M.2 to plain SATA.
BTW, SFF8639 adapters work because the U2 SAS cable also has the PCIe signals.
