MP 1,1-5,1 Mac OS 11.3 has broken support for older Mac Pros

[Runsc]

My machine behaves exactly as TECK described in #300. I installed Mojave on a SSD in bay 1. Then I pulled all HDD sleds except for bay 1. Then I downloaded Martin's Package and installed it by the book on the EFI partition of the Mojave drive. Boot picker worked. After that I put the sled for bay 2 with another SSD back in. Then I downloaded Big Sur 11.3 and started the installer from Mojave an installed on the bay 2 SSD.
The install hung once with a progress bar freeze. After a forced shut down it ran through.
Then I moved OC to the Big Sur drives EFI partition. Everything works. The only problems I have are the warm boot issues, the messages that I did not shut down the machine correctly and mysterious recovered files in the trash.

Hours later and after wasting much time: OCLP does very little for me. Reboots mostly fail, cold boots mostly work.
Back to waiting for smarter people than me to hopefully get to the bottom of this for 11.3/11.3.1.

Well, the OCLP team never claimed to have resolved the issue and it is still an open issue with them.

I'll suggest keeping an eye on the developments with the OCLP. The team is essentially part of the OpenCore team and the project is a semi official part of the OpenCore Project.

The solutions for many of the knottiest issues faced have ultimately come from that project...
- Acceleration with Legacy GPUs
- Legacy Audio Fixes
- Built-in protection from unwanted firmware and SMC updates
... to name a few.

We can then look into applying it in a minimalised manner here for those that prefer such although ultimately, with each release of Mac OS, it is likely the OCLP will become the way to implement OC as it now includes Rigid Patching (filesystem writes).
The cMP 3,1 to 5,1 have not needed this so far but this is not likely to last and there is a high probability the solution to this particular cMP 5,1 issue will involve this.

There has been a fair bit of noise in terms of reports recently that cloud the picture but hopefully the frenzy will settle down after a while and it will be possible to systematically investigate the issue and hopefully push clear findings to OCLP team etc.

People are obviously willing and trying to contribute which is great .... just needs a bit of structure. Hopefully with time, we can get more structured reports similar to this which consolidates tests done and gives a clear outcome.

I used several times the original Apple wired keyboard/mouse, no issues. That’s how I fix the Bluetooth bug in Big Sur, when I switch from Mojave. I don’t own any generic USB keyboard, only Apple. I do use a Scarlett 2i2 USB2 audio interface, functional in Mojave, Big Sur and Windows.

Can you boot without OC just
-no_compat_check?

 

[socamx]

Why people use OCLP to start with?

Because I wanted to see first hand for myself that OCLP isn't the answer. As you saw, I used a guinea pig cMP. Curiosity got the best of me and I had nothing to lose but some time.

The guide here on the forums for OpenCore is still 100% the way to go but I can appreciate that OCLP is trying to streamline it and make it easier to do at least.

Big Sur 11.3.1 Doesn't t work on Macpro 5.1 with Opencore 068 Martin Lo

Nevermind

Big Sur 11.3.1 Doesn't t work on Macpro 5.1 with Opencore 068 Martin Lo

I just updated to Big Sur 11.3.1 and Opencore 069 Martin Lo and it works for me.

It's not working if you're having booting issues. That's kind of the point here.

And that's the fact what's holding me back from updating ?

Thank you guys for testing and investigating! I hope, we will know what's up at some point...

 

[trifero]

It´s a mess. Mixed OC, OCLP and patched systems.

 

[KevinClark]

Does it really work with Opencore Martin Lo 069 Big Sur 11.3.1 on Macpro 2010 ???

If you're lucky...maybe
I wouldn't try it at this time. Just wait until there is a real and reliable solution.

Plus OCLP is very limited, configuration wise. Looking quickly at the code, it looks like it was designed for a drop-in setup recipe, which IMO is not the right approach. Not to mention they use their own OC binaries, instead of pulling them directly from Acidanthera repo.

1. Drop-in setup? We do hardware probes when the hardware is present and apply appropriate patches, see our logic for DeviceProperties probing with DRM, Wireless and NVMe patches
2. We have never used our "own" OC binaries, we build from source whenever we need latest (ie. when ForceBooterSignature was added). We work directly with Vit and we integrate new patches in rolling releases almost immediately, and these binaries are both documented with exact commit version and date as well as easily accessible on our build system: Dortania Builds. No custom builds are used, it's all public code.

So please, don't disrespect others works and make false claims... If you have issue with our work, then reach out and tell us how we can improve. We're not shy to the idea of constructive criticism, but punching down does nothing productive besides tell us that the Mac Pro community wants us to leave and not provide any resources or patches to you. Is that the kind of toxic, gatekeeper community you're proud of running?

I really hope our cMPro 5.1 can continue to update with working PCIe NVMe. I know all the people here are working very hard and their talent will become to be a new success. I know Opencore Legacy Patcher team too.

Look, My very old MacBook Pro 4,1 Early 2008 had been inside a drawer until yesterday. I have used OCLP (I knew about it in this very thread). Now, it runs BigSur 11.3.1 reasonably smooth considering it is 13y old with no metal graphic card. Everything works!! (SSD, BT and wifi, trackpad, sound, camera). It works even better than with DosDude1´s Catalina patcher, which is very surprising.

I am sure someone here or there (or the cooperation of both) will find a solution for PCIe issue in cMPro. Anyway, many thanks to all of you.

 

[TECK]

What's your exact hardware spec.

Signature up to date, dual CPU, GPU with dual ROMs.

Do you know if there is any similarity with the other three users

@Runsc (see #8,030 and #576) reported successful upgrades, this is the only person I could trace back the posts. There are others, I remember a post where someone have 2 Mac, one successfully upgraded.

What's connected to the cMP, and which port?

Dell UP3214Q with cable connected on Mini DisplayPort to RX580 DisplayPort:

Scarlett 2i2 connected to back USB2 port:

CyberPower UPS connected to back USB2 port:

Apple Bluetooth Magic keyboard and Magic2 mouse:

Where you install OC?

EFI disk1s1 partition:

So please, don't disrespect others works and make false claims

Nobody is disrespecting anything, I wanted to highlight that you are injecting code and components you build yourself from source and offer it to people as a package installer. That's all. I personally believe this is not the right approach. Acidanthera provides a very comprehensive manual for configuring OpenCore. To get the most out of OpenCore, it is important to read the manual and understand its settings, not use a system that does everything for end-user without understanding anything behind the scenes. I believe @vit9696 shares also this philosophy.

Feel free to reach at me with a PM, if you want to talk more about it.

I have already 11.3.1 but random boot successful with Highpoint 7101a. I also try OCLP but it still stuck. Don't use nvmefix.kext, it even can't boot

@VitaminK Could you please change the first post to a wiki? Let's write all the pertinent info there.

 

[TECK]

Let's write all the pertinent info there.

I think we should also have attached a minimal EFI based on @cdf guide, for people to test quickly as alternative to their current OC setup.

Oh! For you anything. Done.

Let’s not attack others or their work (obviously not direct towards you khronokernel), Opencore Legacy Patcher has come along way. Highly recommend.

A lot of us just want something that works and is easy to install. OCLP provides that path for a lot of users. I don't have a desire or need to spend hours tweaking settings inside OpenCore. I just want to be able to run Big Sur with the minimal amount of fuss.

which solution

 

[tsialex]

macOS Big Sur 11.4 Beta 2 (20F5055c) was just released in the developer channel.

Edit:

It's an update release, no full installer at this point.

 

[VitaminK]

Updated. two reboots for the installer to start, couple more to boot. Everything still supported
