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

[Laurentfr45]

My tests with 11.4 a few pages back in this thread were done with OC 0.6.8. And they were unsuccessful. See if you can replicate the number of boots that I have in those tests without any panic issue. And if successful, then duplicate the number of boots to see if you can match JohnD record. Otherwise, unfortunately it is hard to believe that your system has no (potential) boot issues at this time.

EDIT: ...and here more 11.4 tests with SIP disabled

Hi
thank you for your feedback and I read all your tests and I follow the thread since the beginning, for my part I find my system more stable now
with 11.4 than it was with 11.3.2 I don't push the mac to the error to test more, it was just my feedback

Not expecting anything to change. But would be interesting to test macOS Monterey on a 5,1 if that's even possible.

Public beta in July. Theoretically would be possible, but no guarantees things would not massively change between initial beta and public release.

Developer Beta today. I'm sure there are Devs here. But yes, not expecting much.

All devs here are busy, you know, with WWDC this week and all...

Since late-2013 Mac Pro is still supported by macOS Monterey, perhaps we can get it working down the road.

P.S.: I'm really surprised to see 2014 mini still supported. Besides late-2013 Mac Pro being some months older, it's the oldest/weakest Mac supported with other Macs based on the exactly same platform dropped (2014 Air/13" MBP/21,5" iMac).

Most likely it's because they sold the 2014 mini for four years before an updated model was released, whereas the iMac, MBP and MBA are updated nearly every year.

I would give it a try if my MBP M1 wouldn’t have to go back to Apple again

I installed Monterey on my 6,1 (on its own volume). If there's anything in particular you want me to check out let me know.

Does it generally feel like an updated Big Sur UI so far?
Reporting as Version 12.x or something different in initial build?

Thanks (speaking for everyone working on this issue). I'm installing macOS 12 on my 5,1 test machine right now. It's going on an HDD, so will take quite a while to complete. Not expecting any better behavior, but...

Fingers crossed!

Seems Monterey at least boots with a MacPro5,1. A friend got it installed with a supported Mac then booted it with just -no_compat_check and there is a report on the Monterey Unsupported thread that got it installed/booting with OCLP:

macOS 12 Monterey on Unsupported Macs Thread

cMP mid 2012 5,1 installed macOS Monterey with OCLP 0.1.6. No problem to install Monterey, and the installation is faster than Big Sur. GPU Chipset Model: AMD Radeon HD 7950 Type: GPU Bus: PCIe Slot: Slot-1 PCIe Lane Width: x16 VRAM (Total): 3 GB Vendor: AMD...

The million dollar question is, it's like after 11.2.3 or not?

 

[haralds]

The question is whether this is with a PCIe-based disk installed or not.

Don't matter.

Even with nothing connected to the PCIe slots besides the GPU and with the AirPort Extreme removed, eventually you will get KPs on boot with any Big Sur release >11.2.3. It's just a question of enough reboots.

Btw, we will see dozens of reports of Monterey booting with MacPro5,1, but I'm waiting until I can reboot it 20+ times and never get a KP to be at least hopeful.

Yes, in fact it appears to be a slightly updated version of Big Sur, but that’s typical for a 1st beta. It reports as 12.0. I haven’t noticed any interesting updates aside from Safari being a little more streamlined. Several of the new features require a 2018+ or M1 Mac. It might be the most boring release ever, but maybe that’s not a bad thing. Maybe it’ll just be a more stable version of Big Sur.

Is audio out/inputs still supported?

MacPro3,1 experiences more hangs in Monterey than in Big Sur, like every 3 in 10 boots. Compared to Big Sur where it was 1 in 10 boots

Really don't know, totally forgot to ask if the audio still works.

I installed macOS 12 Monterey (DP) and it took several hard power cycles to get it to install. It froze several times, and I got the prohibited symbol once. It took ~10 minutes from the time I typed my login password, to see any activity whatsoever. I'm booting from a 1TB HDD, which is normally painful, but this was excruciating. I suspect there are major changes, and being the first boot, the HDD had a lot of work to do.

The first thing I noticed is my Apple trackpad (original) does not work. It works in 11.3/11.4/11.5, and was upgraded from 11.5b1, so this is something new. I'll see if I can get it to pair again. I'll report any other significant changes that might affect OpenCore / 5,1 Mac Pro. I haven't done reboot testing yet, but based on my installation experience, it seems to be the same as 11.3/11.4/11.5 so far.

PS - Quite a few apps I've tried so far do not run. "This OS is not supported". This drive was originally a clone of my primary system, so I have all the apps to play with. ETHERNET does not work - both ports report "not connected". WiFi does not work. Clicking on status, I get "Preferences Error - There was an error in Network Preferences". com.apple.preference.network.remoteservice crashed hard. Feels like a very early alpha, at least on the 5,1 Mac Pro.

 

[JohnD]

Possibly good news? Someone in the newly-formed "MacOS Monterey" Facebook group got the prohibited symbol installing the DP: "Maybe the 5th try will be the charm? anyone else having issues? Currently trying on an external SSD via a 2018 13” MacBook Pro." Hope that's the race condition affecting a supported machine.

EDIT: Maybe not... "it actually blinked the ? Folder icon 2-3 times, then stopped".

 

[Bmju]

No, but I'm planning to pull several machines soon after the school year is over and give it a go. It will be my first experience with OpenCore, so I expect it will take me a while just to learn that part of the entire process, but I do plan to try Big Sur at some point and will be keeping an eye on this thread and will report what my testing reveals. I've got a significant number of machines with several different hardware configurations; maybe something will reveal itself that hasn't thus far. First I'll be trying to conquer OpenCore and a Catalina install however.

Maybe grab an 11.2 macOS installer before Apple pulls it then? gibMacOS is great for that.

Just installed v12 on a spare disk (good old spinning disk, used to have Sierra).
I had to do 3 cold-boots to install, then it went through.
Seems to get stuck frequently on reboots, but doing fine now on cold boot.
(sudo reboot, getting stuck. Switching off/on -> boots fine!)
Did not do science or stats on it though

• No ethernet (does not connect with the built in ones).
  • Funny enough I can see both interfaces in the System Information dialog and preferences.
  • Giving them a static IP does not work either
• No bluetooth (original). Means no mouse. Keyboard is wired
  • It claims: Bluetooth Hardware is off. Issue is not that it would not find it, it just can't turn it on.
  • Tons of error message on Bluetooth etc when checking the dmesg log...

Don't think version 12 is coming to our salvation, rather adding to the issues we are already having.
Hope they are not removing all "legacy" that kept our MP 5.1 alive...

back to 12.4! Shut down, switched it on, booted into 12.4 instantly. Going to keep it that way as I need it as a productive backup machine.

Exactly the same experience on my test machine, only add System Preferences crashing when I tried to click on WiFi settings. I'm using OpenCore 0.6.9, and Ethernet/WiFi/BlueTooth (stock) were working fine in 11.5b1 before upgrading to Monterey, so it's probably not going to be as simple as injecting kexts to get them working again. Then again, this is just a developer preview - very long way to go.

Has anybody been able to get Music from 11.4 to work on 11.2.3. It most likely would also require CoreAudio framework updates.
The biggest miss apart from security is Lossless and Dolby Atmos. Does not show up in earlier versions of Music.
