This method had been known for some time, even I had talked about it. The only problem is that all the internal temperature sensors are not correctly detected with this string. Can you please check ? Thanks

P.S. I use Macs Fan Control program

I do not use temp sensors, but you are correct, by changing to MacPro7,1 the RAM modules are wonky, (all cosmetic)
-EDIT here's the fix: https://github.com/IOIIIO/MacProMemoryNotificationDisabler/releases/

and I just downloaded istat and it doesn't show temps for CPU or GPU but I haven't found that to be a problem in anyway yet.

If you want to avoid the error report for RAM modules, put SystemProductName = iMacPro1,1 but, you will always have the problem of temperature sensors

I actually found a kext I'm going to try to see if it works. I'll report back on it after a week or so.

Was quite busy, a bit late for the reply. but I think you now know we discussed why we don't spoof the ident to get NightShift, SideCar, etc.

Also, my post about NightShift was about to mean "NightShift Enabler via Lilu won't work". But not "no way to make it work". As mentioned, we already tried the ident spoofing.

I was in rush, and only use simply reply for that poster.
 
That one will not work work with the latest Lilu. You can try my fork

Hm, not sure what to do with the folder full of files that don't look like anything in my OC directory. Maybe it didn't work correctly I'm getting error:

xcode-select: error: tool 'xcodebuild' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance

OpenCore on Legacy Apple Hardware

This guide explains how to use the excellent OpenCore bootloader on a classic Mac Pro to install, run and update macOS Catalina, resulting in a clean, unpatched operating system no different than on a supported Mac.

Why OpenCore?

There are several advantages to using OpenCore on a classic Mac Pro:

Boot picker screen (even with a standard graphics card)
View attachment 916024
Software Update (just like on a supported Mac)
View attachment 882160
Hardware acceleration (and DRM for Netflix on Safari)View attachment 919405
Requirements

Mac Pro modelEarly 2009 with MacPro5,1 firmware,* Mid 2010 or Mid 2012
Processor architectureWestmere (E56xx, L56xx, X56xx) / Gulftown (W36xx)
Boot ROM version144.0.0.0.0*
GraphicsCatalina supported GPU**, EFI (flashed) or a standard UEFI card (PC GPU)

* Need to upgrade? See the upgrade instructions.
** Several GPUs that are supported with High Sierra had support removed from Mojave and Catalina, like any non-Kepler generation NVIDIA GPUs or AMD GPUs earlier than HD 7950. Several HD 78xx GPUs (Pitcairn) were rebadged as R9 2xx and are not supported anymore by Mojave/Catalina drivers. All Mac Pro factory GPUs had support removed with Mojave.

Acknowledgements

A big thank you to @vit9696 and the other talented developers of Acidanthera for making all of this possible. Special gratitude goes to @h9826790 for spearheading the hardware acceleration study and @startergo for the relentless testing that led to boot screen support. And thanks to all those that have contributed to this thread!

Excellent guide :apple:

Thanks really to all of you who make it possible and share with us your knowledge that allows us to continue using our cMP, thanks, thanks ... infinite thanks.


In case my experience when executing your guide can help someone else, first say that everything was as indicated in it but in my specific case I found two problems already solved:

1- Continuity & Handoff stopped working in Catalina with my OSXWIFI Apple Broadcom Bcm94360cd (it did it without problem in Mojave for 2 years with "SystemParameters.plist" code only) but I solved it by following the 2 codes indicated in this thread, part "If you run macOS 10.15+" :

Thanks also !!!

2- My Startech 10 GbE network card (ST10GSPEXNB) disappeared in Catalina, detected without drivers, so restoring with Time machine the driver that it worked in Mojave, is now OK again.

The rest of my hardware that you can see in my signature works without problems, first NVMe with "new Catalina OC", more than excellent Boot picker screen (even with my standard ... Sapphire Pulse RX 580), later on I will encourage hardware acceleration;) but for now I have enough and I am very grateful to all those involved in this ( @cdf , @h9826790 , @tsialex , @crjackson2134 , etc....
 
I have AC wife w/ BT 4.2 on my cMP and Opencore 0.6.3 running Big Sur.

I can't get handoff or Apple Watch unlock working. Allow handoff is enabled and I get the following for Apple Watch unlock but it never enables;

That will bring the memory error popup and sensor issues, then we need to install Lilu with MacProMemoryNotificationDisabler. I'm going to wait until 0.6.4 is out, to sort all bugs. For now I stay with Big Sur minimal setup and no boot Mojave.

I did the sudo mount -uw /
and got this
mount_apfs: volume could not be mounted: Permission denied
mount: / failed with 66

For the next part I got

Can't open /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents/MacOS/AirPortBrcm4360: No such file or directory.

Is there something I'm missing?
