macOS 12 Monterey on Unsupported Macs Thread

[Wickintime]

I have a 2012 iMac, 16Gb RAM and a 500Gb SSD and an upgraded the wifi module.

Using OCLP I was running on Monterey 12.4 and decided to upgrade to 12.5. However I was too quick off the mark, before the alerts came out about the Kepler graphics problem. All was well until the reboot when it all went to worms. All I had was a constant reboot cycle and then that stopped. I'll miss out the things I've tried, but I now have the situation where the SSD has been erased and I still can't get any working OS loaded. A few days ago I did manage to boot into safety mode and managed a restore off the internet but only Mountain Lion and only on an external HDD. I could not load this onto the SSD as it could not be accessed by the OS. As soon as I tried to upgrade (to Catalina) it loaded as far as the first reboot and then said a problem occurred and it was back to a restart. Whatever I try to do now I end up with with the restore screen only being able to access the Catalina OS download which it cannot complete. I need help!

I put this on the Monterey thread as that's where I began and where I wish to return to!

Thanks for any helpful comments.

Stating the obvious here, but if you want to go back to Monterey 12.4, you need the 12.4 installer and OCLP on a USB stick. Boot from that USB stick and install 12.4 again?

Hello rehkram,


I noted your response to my post. I usually recluse myself from "conversations" which enter realm of emotion driven statements. This time, however, "I'll bite", to paraphrase another user.


I have utmost respect for developers, their work is amazing, but it is not dogma. Statements, which developers publish, are often advisories, many directed at people who might be tempted to install untested solutions on mission critical devices. There are participants in this forum with various levels of computer skills and experience, so caution is advisable. Conversely, there are just as many posters on this forum who are well aware of the risks, and take steps needed to protect their data, while providing test beds for developers' programs. Often, that "cooperation" results in discoveries that lead to solutions applicable to everyone. I belong to the latter group.

"Supposition" by its very definition, and as employed in the sentence, equates its meaning to "conspiracy theories", e.g., it's a well intentioned quip. Finally, let me know, which of my posts seemingly contradict statements (within known parameters of non- metal machines), that Monterey 12.5 RC runs perfectly well on the MacBook Pro 5,2 and Monterey 12.5 beta2 runs just as well on (metal compatible) iMac 13,2?


Above all, we are colleagues on this forum.

Just as a follow-on on this. I think what we're lacking is a definitive list of the unsupported laptops that can run 12.5 'stand alone', i.e. without an external monitor, and which ones can not.

In my direct experience, the rMBP 10,1 mid 2012 can run 12.5 stand alone with the Kepler dGPU enabled, but not with an external monitor. Disabling the dGPU would mean I couldn't run an external display on it either so doesn't get me anywhere; there's no point in disabling the card when you're running the m/c stand alone, it works fine.

The other permutation to consider is the version(s) of OCLP we know it will (or can) work with. 048 is working for me.

To sum up my current status all I've really lost for now is the external display via wired connection. The m/c is fully functional in all other respects. I can still bring it up on the external display using Screen Sharing over the LAN (rather than a direct wired connection using TB2 -> DisplayPort) from my Mac mini. It's a tad slower for YouTube vids but I just watch them on the mini instead.

It could be worse!

That's exactly what I was thinking. I've also had mixed results with Migration assistant. I solved them by doing another clean install and manual user setup and data restore. Also, maybe try an NVRAM reset at some point. But I'm just guessing here.

Re. restoring the data files, I moved all my data files to iCloud this week. It is making my life a lot easier. I set up 'Projects' folders on both desktops, moved all the data subfolders into them, then specified to store the Desktops in the cloud. Did it on both my production machines. After a clean install and user setup, after logging back in to iCloud I can access everything from either m/c without restoring manually. This greatly simplifies the whole process.

To communicate closure on this issue,
where the user upgraded their late 2012 iMac, 13,2, with Kepler GPU, from 12.4 to 12.5.
hosing their machine.

I ended up doing a clean erase & install of 12.4 to the iMac.
I then used their time machine back up, and restored their iMac system, to a volume on my 2020 Intel iMac, So I could gather all their data, apps and configurations, and essentially replicated their system, back to their iMac.

The moral of this Story is do not give administration rights to a user, running an unsupported iMac.

Hi friends! Hope you all are having a good day.

I decided to downgrade my cMP4,1->5,1 to Catalina (using Dosdude1 patcher) while I can't resolve or discover what hardware are not working with Monterey. There are some detail more than simply erasing the drive and reinstall Catalina with the installer created? I erased the nvme but the OCLP icon still appearing in boot picker... And the installer can't reach the end. I reinsalled the original NVidia GT120 to run Apple boot selector...

Thanks!

EDIT: after install, I needed to remove GT120 GPU and the process finishes with success.
EDIT 2: Error related to Apple Secure Boot from NVMe drive... If you have some help it will be welcome!

Thanks again!

In my direct experience, the rMBP 10,1 mid 2012 can run 12.5 stand alone with the Kepler dGPU enabled, but not with an external monitor.

Hello. I have the same rMBP 10,1 but could not get Photos and some other apps to show but only got a black screen that I could get out of by command-Q. Are you saying that Photos is also working for you if I may ask?

I use gfxCardStatus - https://gfx.io/ - to disable gpu switching and photos works ok, not the external monitor unfortunately. MBP 10,1 mid 2012

Photos is working, yes. I don't know what the difference is between our configurations, I haven't done anything to make it work. It also works when screen sharing. Photos is Version 7.0 (460.0.120)

I did do an NVRAM reset before reinstalling OCLP 048 though.

Here's a screenshot:

what were your issues?

I have several cMP4,1->5,1 running Monterey via OCLP they all work well.

you might find more assistance if you out in the Mac Pro forum. Tere is specific thread for cMP running Monterey

You are right, I just tested full screen and it did crash, threw me back to the login screen.

 

[TOM1211]

On MacBook Pro 2014 photos will crash when plugged in because it uses the nvidia unplugged it will use the lris pro on automatic graphics switching . After using micropatcher to go back to 12.4 if I try to enable sip it’s fine on reboot but even on 12.4 will still black screen when trying to use nvidia so think clean install is only way back .
Update: in the interest of trying again after using micropatcher to patch the install to go from 12.5 to 12.4 then reinstalling 12.4 over 12.4 without the patches I can enable sip again no black screen with nvidia and keeping all my data.

Hello @LuisN
Interesting, this is new info to me.
Are you using 12.5 with this software? I assume the HDMI connector will not work either with this though?
Have you tested?
Many thanks.

 

[Pachnes]

this is very rude of apple ,,,
ok, maybe they did fire the chief of kepler driver and all the team.

they do this in usa, verry poor and pitty.

it would not be possible in european market, to fire a head developer of a hardware, because the hardware is obsolet. the comnany must find him a new job at the same level of hierarchy in the company.

I installed gfxCardStatus, disabled the dGPU, Photos now works in full screen on the laptop's display as Luis said.

If I plug in to the external monitor with the nVidia card disabled it does not work, throws you back to login as before. I tried both HDMI and TB2 > DisplayPort. I tried rebooting, it still fails.

This is a crazy take, I'm in no way defending Apple, but why they would still keep supporting a 3rd party graphics architecture that no supported Mac have since Big Sur?

Macs with Kepler NVIDA GPUs were released in 2012/2013 and was used with just one MacBook Pro model back in 2014, we are now in 2022…

So, in your view Apple should keep supporting NVIDIA made drivers forever? Drivers that NVIDIA itself ended support a year ago even with Windows?

You assume right. Connecting HDMI always forces Nvidia graphics and all goes black

I don't even know what you're talking about. Head developer of a hardware? Jeez...
I'm European by the way

MBP5,2 successfully OTA updated from 12.4 to 12.5, using OCLP 0.4.9 including for root patching.
No problems seen. Photos fine also in full screen. Running with Nvidia GeForce 9400M.

That’s just plain false. Workers are being laid off in European factories because of changing business environment, production demand and technology shifts. It’s advised to find them another job within the organisation, but if there isn’t any, there is a severation package and they can seek another job.

MBP 10,2 works also flawlessly with 12.5 and 0.4.9.

Apple had a feud with Nvidia many years ago. As far as I could recall, it was because Nvidia wanted Nvidia's proprietary API, CUDA, and Apple wanted Apple's proprietary API, Metal. As a result, Apple switched to AMD in 2014 and never shipped any Nvidia GPU since then.

As late as Big Sur, there was still the Kepler Metal driver. Given the feud was pretty public back then, I do not blame Apple for what it is doing right now (despite being the proud owner of a Kepler iMac). I do blame for what it did back then!

 

[MacRumors3590]

Seems to me peeps are getting kranky for a Kepler fix lol.
Including me!
<--Fingers crossed

EDIT - THANKS YOU!!!!!!!!!!! HOORAYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

 

[makra]

0.4.10 with the Kepler fix is out!

 

[TOM1211]

0.4.10 with the Kepler fix is out!

amazing at the quick fix for this I appreciate the effort that goes into this big thanks to those involved in patches and testing .
