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

[startergo]

I would wait untill the official release.

 

[Dayo]

I will try to update the NVME driver inside the firmware from the MP6,1 firmware.

Did you manage to pull this off?

Sure but it does not help.

Earlier KP posted suggests one or more of these might be the issue. Was hoping it was AMFI.

Beta 8 is out, fingers crossed ?

Don't keep your hopes high. Read previous posts.

Interesting. I checked my computer in the morning and I saw NVMe kernel panic. Did NVRAM reset and found that Macintosh HD was missing from the boot picker. Booted to Big Sur and saw 10 minutes remaining (for installation). After booting to BS I realized that:
System Version: macOS 11.3 (20E5231a)
@Dayo the only different thing is RP X124 and the commit 562f85685daa0aed7d98c591d39b8784e5519021 of OC.

So this means what? I could stay at 11.2.3 for a while, but i hope we will be able to update again in the future...

 

[Dayo]

RefindPlus X124 angle probably just a coincidence (change is only in the ReloadGOP part).
You could try old RP with the new OC to confirm.

 

[startergo]

I still got a panic on a reboot. Did an nvram reset again. Still panics
IoplatformPanicAction --> IONVMecontroller
IoplatformPanicAction --> AppleAHCIDiskdriver
IoplatformPanicAction --> AppleAHCIDiskdriver

IoplatformPanicAction --> AppleAHCIDiskdriver
IoplatformPanicAction --> AppleSMC

Some sort of patch needed on the NVMe kexts maybe?

 

[VitaminK]

Could be just imagining this but had really good luck with an Opencore delay of 30 seconds, waiting for the time out to boot Mac OS 11.3 from a fresh startup. like 3 out of 4 good boots

IONVMEFamily fails but continues to boot sometimes

Hmm, I just waited 40-50 seconds at the OC boot picker and it booted. Go figure.

Edit:
It must have been a fluke. For me it boots once per n attempt. Where n is an unknown.

 

[Macschrauber]

Its not just nvme, had the same freeze with an ahci blade.

Did you check which kexts are mentioned in the backtrace in this case?

 

[KevinClark]

maybe it's a bug

 

[pure.wisdom]

Does anyone have a link to download beta 2? Thank you so much

 

[TECK]

It seems weird to me to complain about a compatibility issue with a non-supported system. Big Sur isn’t suppose to work on 5,1 and older. You need a 6,1 or newer for Big Sur.

If you don't post something useful, please refrain from posting. All it does it creates noise, thank you.

Anyone using a Syba SI-PEX40129, with kernel panics on 11.3 beta?

Latest 11.3 beta is 7, see https://developer.apple.com/support/install-beta/

 

[KevinClark]

Replace the nvme io by thé older

You have to patch the symbols first.

 

[KevinClark]

Yes

 

[startergo]

Yes

Symbols exported by both xnu and Apple kernel extensions will change. Recompile your kernel extension with each update to macOS Big Sur 11 beta to ensure compatibility. (64262563)

Do you have the source code for the kext?
If not how do you intend to recompile it?

I have 2,5"-SSD on a OWC Mercury Accelsior 6-card. Can I install 11.3 without problems?
