MP 1,1-5,1 Obsolete, Use OpenCore instead | What you need to do to make Catalina work with MacPro5,1

But... I'm running socket 1366's... and ECC RAM is a requirement... and macOS says ECC is enabled. Lies?

macOS shows that the memory you have support ECC, but in the memory controller of any i7 1366 socket ECC support don't work since it's disabled.

Read @handheldgames posts about it.

Can confirm this works on iMac 12,1. Using the original graphics card. Not many issues with the UI. Crazy, thought that metal would make it crazy, like the mojave update.

 

[Hunterkillz123]

Any issues with the Mac 5,1 catching under the Apple sign after using the recover command method? I am stuck at about 50%.
Been this way for about 10 mins.

If you used a supported Mac to install and used -no_compat_check to bypass the distribution file, you can't clear the NVRAM. To overcome that, just add Mac-F221BEC8 to SupportedBoardIds and add MacPro5,1 to SupportedModelProperties.

You have to do it in two places:

First one, from the /System/Library/CoreServices/PlatformSupport.plist

/System/Library/CoreServices/PlatformSupport.plist

The second one, from the same file in the Preboot volume. You have to mount the Preboot volume first, than go to

/Volume/Preboot/xxxx-xxxxx-xxxx-xxxx/System/Library/CoreServices/PlatformSupport.plist

Example:
View attachment 841462

SupportedBoardIds for MP5,1 is:

<string>Mac-F221BEC8</string>

SupportedModelProperties for MP5,1 is:

<string>MacPro5,1</string>

How do you edit PlatformSupport.plist on the Preboot volume? I just get "No such file or directory"

Thanks

Ok, so I’m new here. Not trynna cause issues, does that mean that I need to boot this file into Linux and alter the files? Or can I do that through the recover terminal? Thanks in advance

Guys stop complicating your life Catalina now makes system drive read only so you need to make it read/write to make changes. You don't have to make any extra moves to install Catalina with dosdude's USB. It behaves like a regular install.

I did that install. It failed, COULDNT get any output from a AMD570, that’s why I liked this better.

Just use the -no_compat_check. If you edit PlatformSupport.plist, you will have to do it again every new DP.

I did this and it failed. I will try again, maybe I’m incorrect on execution.

I did this last night on the 12,1 iMac no issues. So I know it works on 12,1 iMac. Seems like it would also work on this the same.

If you use a supported Mac to install, you just need -no_compat_check to run it with a MP5,1 that have a Mojave supported Metal GPU.

Other install methods have other requirements.

Would using a efi-card non-metal cause it to catch at 75%? All I have that I can see the boot is non-metal.

Don't know, never tested without a Mojave METAL supported GPU.

Apple released Catalina DP3, build 19A501i:

Still blocks MP5,1, hope never ends

[doublepost=1562092550][/doublepost]Seems Apple is releasing new firmwares for Catalina supported Macs, EFICheck AllowListAll was updated too.

[doublepost=1562092639][/doublepost]DP3 is a full install only and it's 7,42GB download.

 

[tsialex]

New CommandLineTools too.

 

[Fangio]

Ta-daah – WiFi is back in 19A501i with the 1.0b6 patcher post install





obviously the Mojave AirPortBrcm4331.kext is included in b6. Nice!

 

[Hunterkillz123]

Anyone tried this method with a amd 560? I haven’t gotten mine to show any screen other than recovery. But once booted in, nothing. Just shows as “display”. Thanks in advance.

 

[tsialex]

DP3 still installs as the previous versions when you use VMware Fusion and a rawDisk. Keyboard still don't work.

 

[PeterHolbrook]

Is there a way to download the "delta" version of DP3 to install on top of a DP2 Fusion virtual machine? Oddly enough Software Update doesn't seem aware of the update at all.

Software update only works with supported Macs and don't work with Fusion at the present release, 11.1.

DP2 and DP3 are full installs, there are no deltas.

Edited the previous post to "Sidecar needs native HEVC encoding support, all Skylake and newer Macs does HEVC encoding with QuickSync except iMac Pro which uses GPU HEVC encoding"

• InsanelyMac Legend sais :I managed to make Sidecar work with my Mid 2014 MacBook Pro work and iPad Pro. It’s great in terms of minimal lag, but the image quality is bad. I guess the limitation is about hardware HEVC encoding which requires Intel Core 6th gen processoHere’

Okay, I finally got it installed with the dosdude method after several failures (it may have been a faulty usb drive). Using 19A487m version with Nvidia GT640 PC Card, no black bars on Safari or any other glitches. Could not get -no_compat_check to work at all on any install. Thanks for your help, and keep up the good work.

Actually, that boot option is integrated in the installer. You can check with:

sudo nvram -p

I could not get this method to work either. Downloaded on a supported Mac (2018 Mini using an external 2.5” SSD, then transferred to flashed 5,1 Mac Pro), then entered the “no_compat_check” in Recovery. Just got a circle with a slash through it upon booting with the transferred SSD installed.

Might have to go with dosdude’s USB install. Will try one more time before I resort to another method, since so many others have reported success.

It's -no_compat_check, not no_compat_check.

sudo nvram boot-args="-no_compat_check"

I'm using a more focussed check, this one
