For your tooltips issue, you can boot Catalina without OC, then you will know if that's OpenCore related in few minutes. And if not, then you better open another thread in the Catalina forum for this particular issue.
I thought OpenCore was needed at all times for Catalina (unpatched) to run on a 5,1 but maybe I'm misunderstanding things. Is OpenCore only needed for the installation part?
 
OpenCore is needed to boot Catalina unpatched.
This is NOT correct.

We can install unpatch Catalina from a VM, or another Mac. Then all we need is just a no compat check boot argument to boot unpatch Catalina on cMP.

OpenCore is our recommended method, which can provide boot picker, HWAccel, and allow us to boot to Catalina recovery partition etc. However, never a requirement to install / run vanilla Catalina on cMP.

Since you already have Catalina installed, all you need now is just that boot argument to boot Catalina, and test if tooltips can work properly.

This I knew. But according to the stickey adding the boot argument isn't the preferred method since the creation of OpenCore. So, it's not a consideration anymore per @tsialex.

"Preferred method" is NOT "required / needed".

And if you follow the entire story, you should know that I suggested him to boot Catalina without OC for diagnostic purpose (because he suspect OC cause tooltips issue). I never say that's my recommended way to run Catalina on cMP.

You are being too literal, the intention is to try to identify what is really causing the problem, taking OC out of the picture is useful in this diagnostic scenario.

Using -no_compat_check is extremely inconvenient nowadays, OpenCore can provide native installs and updates while disabling the compatibility check can't, but it's very useful to identify if some problem is related to OC configuration or the Catalina install itself.

Previous advice to the same poster on a similar situation:
you should have tried pulling the disk with OpenCore and then booting into Mojave directly to verify that your issues are related to OpenCore being present as a first step before reaching a conclusion about this. That is, remove "Y" from the equation and see whether "Z" is still present.
 
As was posted earlier already: here

the problem I was having with tooltips, was NOT related to OC in any way, shape or form.... see above post for the details. Tooltip problem NOT related to OC or hardware acceleration or anything related to OC. Sorry for the bandwidth and thanks to others for pointing me in the right direction to figure it out.

I stand corrected...
 
Does OpenCore resolve the USB issues for Big Sur?
- USB HID devices on system bus not recognized if inserted after boot
- USB 3 add on media devices (auto and video) not smooth
This was not an issue with earlier Big Sur betas, but is a problem now.
 
Can you disconnect/reconnect the USB keyboard or mouse in the back/front USB ports without loosing functionality? Are you using any SMBIOS spoofing?
SMBIOS spoofing? I honestly have no idea. I have the Logitec G512 Keyboard and have my MX Master 3 dongle plugged into the keyboard itself. Then, the keyboard is plugged into the back.

To answer your question though, the same problem occurs when the mouse or keyboard is plugged into the front USB ports.

That answer was to another user who claimed there were no problems on his computer. I know there are problems with the USB and they actually are related to Big Sur itself not particularly to the cMP.

Would getting a PCIe USB 3.0 hub potentially solve this issue?
 
URGENT QUESTION: I want to enable hardware acceleration according to this post, but there's a mention of danger with dual booting.

Since I have no boot screen, I currently use System Preferences to select my startup disk if I want to get into Windows 10, and from Windows I use Bootcamp Assistant if I want to get back to macOS.

If I install this hwaccel patch, am I going to wreck my ability to get back and forth between OSs?

Maybe the aluminum USB keyboard does not have this issue as implied in the previous comment?
for me some devices have this issue and some others don't.

I also have the compact apple aluminum wired keyboard and I can reconnect it just fine, but my Logitech mouse doesn't .
he even admitted he had to use a hub to fix his midi issues lol.

bottom line is, some devices reconnect, some don't.

why don't you have boot screen? what's stopping you from following the guide and getting it?
I'm also dual booting windows and Catalina on one 5,1 with full HW acc. it works just fine.

I must preface this answer by saying that I am an amateur who has simply tried to follow the instructions in the earlier posts.

I assume that you mean you have not yet set up OpenCore and, if so, your system is essentially the same as the one I had before moving to an OpenCore setup. If this is the case then your Windows 10 SSD will be legacy boot and you will have to change that to UEFI fo make it work with OpenCore. I followed the instructions in the first post to the letter and reinstalled both MacOS and Windows 10 on NVMe drives (using really cheap PCIe cards). It took a while to get it right, but I now have the OpenCore boot screen, which allows me to switch between Catalina and Windows 10 by simply selecting the disk rather than having to reset the NVRAM to get back to MacOS (I didn't use Bootcamp).

The bottom line is that if you want the hwaccel patch you will have to install OpenCore and if you install OpenCore your current legacy boot Windows will have to be changed to UEFI in order for OpenCore to recognise it.

I hope this helps.

Hello
I tried to start my Mac Pro today without lilu and WhateverGreen, it didn't work. My Mac boots normally up but then my monitor just stayed black. I use in my Mac the Readeon RX 560. Does anyone have an idea what this is due to?
Thanks in advance!

The iMac Pro board ID which to activate HWAccel makes the macOS believe that you are running an iMac Pro with just one internal monitor. Therefore, only one of the graphic card's port still work.

To work around this, we use Lilu + WEG, then make the "board id -> board ix" patch. So that all ports can work again.

You removed Lilu and WEG, which also disabled the board ix patch. And most likely you haven't connected the monitor to the "right port", that's why stay back.
 
Thank you for the great explanation but I thought lilu and WEG were broken in Big Sur. This happened to me in Big Sur. I’m confused right now.

You must use the Mac Pro 7,1 board ID

Really been months since I want to install it in my Mac Pro. But reading this thread it frightens me.
