I have been unable to get Sidecar to work on my 5,1. I have an updated WIFI and Bluetooth card. I see sidecar and It even shows my iPad but then it just flickers the iPad’s screen and throws an error message.
Got a tip for us?

While FeatureUnlock (included in Martin's package) will make the Sidecar pane appear in System Information, the feature will not work on the MacPro5,1 because it lacks an iGPU.
Well whaddya know... it DOES work with simply copy and replace.
Nice and happy running 11.6.1, though not happy when Safari was subsequently updated and lost all its open tabs, can't reopen previous session, and history only shows up to April 2021.
Hello, I have a 5,1 Mac Pro. Today is my first day attempting to use Open Core. I followed videos and text from martin Lo, and I watched the video series "Open Core - The Basic Way" by Joerg Henninges.
The changes were going well until I tried to upgrade to Big Sur. For some reason, my computer seems to be constantly booting up. The term on google appears to be "boot loop."
Unfortuntately, I have not been able to find any solutions. If anybody has any suggestions, I would greatly appreciate the help.
My original OS was the 10.14.6 version of Mojave. I have a Flashed GTX 680. Nothing has been modded internally—just basic HD to 2.5 SD upgrades and RAm upgrades (Single Tray).

I don't understand why you are using a ready made OpenCore solution tailored for AMD GPUs with a NVIDIA GTX 680?
Maybe using OCLP 0.3.0 will work better and be easier for you, since you are starting with OpenCore.

I brought this up on the Open-Core support group before I started. The problems started when I tried to update to Big Sur. The members told me that Nvidia GTX 680 would work fine... and it did. I'll check out your link, though.I don't understand why you are using a ready made OpenCore solution tailored for AMD GPUs with a NVIDIA GTX 680?

Update: My computer finally booted up. I now have Big Sur on my Mac Pro 5,1. However, it looks like I've lost access to the internet. I believe there's a video for this. I am now going to search that video to see if there's a solution there for me. Hopefully, things will go well. Thanks
No, NVIDIA GPUs don't have hardware assisted compression/decompression/conversion/grading with macOS like AMD GPUs after RX 460 have, what is commonly called AMD hardware acceleration. This is the main focus of the solution of this thread.
Btw, with this package you won't get the display port from NVIDIA GPUs to work, while OCLP have a solution for this issue and probably will get your original AirPort Extreme working again.
Look at the options mentioned in the setup post in this thread. If you still have a legacy WIFI card in your 5,1, there is a change you have to make in the OC config file to re-enable it. If you put a modern WIFI card in, it will be natively supported in Big Sur. ‘Additional Option 4”: https://forums.macrumors.com/thread...n.2180095/page-53?post=28255048#post-28255048
Thanks for this, I need this change for my 6 core MP5,1 until I get the wifi and bluetooth upgrade. I was searching and couldn't find it. Much appreciated.
I was running Opencore 7.2 from Martin on Big Sur 11.6 on MacPro5,1 spoofed as a MacPro7,1, and it was working pretty well; however, it was a bit sluggish until Jessie's Flying on YouTube discovered spoofing cuts your speed in half. I've upgraded to Martin's Opencore 7.4 with the Slur Plus path, copying over required attributes and the memory mappings to the new config.plist, no longer spoofing, and everything is snappy again.
However, the system isn't stable where once a day, all running apps crash and cannot be re-launched. A complete system reboot is required. Attached is a log of one of many crashed apps with the same error.
I'm guessing this is related to the floating-point memory issue with 11.6, but I thought that is what the Slur Plus patch addressed.
Anyone else experiencing this or have any suggestions for remediating this?

Could you elaborate on this? Because a minimum of spoofing is a requirement for hardware acceleration on the MacPro5,1...
Thank you, I have to go to work, but I will look through this and try it when I get home. I'm going to look into a wifi card replacement as well when I get the chance. Best!
Seems that even using the VMM flags trick, the latest RC doesn't show in the Software Update panel. I guess if something new is needed for this latest and ( may be ) final release.
EDITED: Thanks to user @GSXB, apart of changing the VMM flags to "on", I changed the SecureBootModel from Disable to Default and that showed the update. But unfortunately after 2 reboots trying to update the system, it returns to the previous Beta 9 I have installed in my MP 4,1->5,1. Same behavior I had when trying to update from Beta 4 to Beta 8. At that time the VMM flag trick worked, but not now. Seems something is still missing. People are installing the latest OCLP 0.3.1 nightly build that seems to work but I would like to stick with Martin Lo's OC as it have been working fine for me for several years. And honestly I don't know how to make the change neither if needed, but hope a new trick could be apply to Martin's OC.

I also tried using the 0.7.4 to upgrade to Monterey via the Apple beta program methods. The installer runs, does a restart then I see a new "Macintosh HD" option at the start screen.
That runs briefly, reaches about 35% of the progress bar then goes no further. The normal option for my Mac OS just goes back to 11.6 and nothing further happens.
I guess that's the same behaviour as above. Just noting the behaviour.

The user @ghost82 have the answer at Monterey forum from a chat with khronokernel, and it's this:
"Apple removed VMM from the Pallas Catalog temporarily, should be restored in the coming days. Either use a non-T2 SMBIOS or set SecureBootModel with a T2 ID and ensure VMM is not exposed
Nothing to be done on our end, wait for Apple to fix this"
So we have to wait for this to be fixed... If Apple decide to do so, or somebody finds a new trick.
All was well, then ooops - I Wanted the cool new tracking features in FCP 5.6 whilst I was on the older BigSur 11.2 - FCP 5.6 is not available in 11.2 - so sadly i clicked the system-upgrade to the latest BigSur 11.3 without first updating OC 0.7.4 or adding SurPlus ! 🙁 not a good idea. My bad. Now it won't boot from the nVMe. Anyway can anybody suggest the best path to make a USB-bootable system for a 5,1. They do/dont boot from a bootable Catalina USB? or do i need a bootable Mojave USB?
Did the install even finish? From my experience without the OC (and Surplus) then the install won't even complete.
If it did finish, then you'd need OC on a USB or some older HDD (mount the EFI partition) then bless that and it should hopefully work.
I always keep a Mojave install on another HDD which I can put in the computer as an emergency option.
That's right - if I do something with OC and it doesn't work out - then Mojave is my backup to get the computer started.
Normally I have OC on the same drive as my install of 11.6 - but if that stops working (usually because I stuffed up something) I can put in Mojave HDD and it will start again then I can fix it up.
I'm still a bit of a newcomer to this stuff compared to the experts here.
I also keep the old Radeon 5870 1GB graphics card that I can put in the computer in case I need to be able to see the default Mac startup screens. The 5870 will even work in Big Sur, but very, very slowly. It's enough for recovery purposes.

I finally have been able to update from Beta 9 to RC2. The description of what I did is in the OpenCore on the MacPro forum, starting at post #9230 ( https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/page-370 ). Here it is my own config.plist modified as explained there. Hope it can help you to update your system too.
