macOS 12 Monterey on Unsupported Macs Thread

[borp99]

Both the 12.5.1 (21G83) builds available with gibMacOS and Download Full Installer (ie. added at 17:22:45 and 21:23:50 on August 17) are the same 12,448,176,349 bytes (12.44 GB) in size. OKonnel's post above prompted me to download the later one too, in case it was markedly different in some way or even slightly different in size. [NB. mrmacintosh.com only has one of the two installers listed]

It seems reasonable to assume that nothing changed between the two sets of installer files and the current choice of two is unnecessarily confusing.

I installed the earlier 12.5.1 download on my 5,1. It runs just fine, although I still often have to boot with Cmd+V from OCLP 0.4.10 if the non-verbose boot process bar halts completely about a 1/3rd of the way along (which has been happening for me quite often with numerous recent Monterey builds and OCLP versions). I'm not sure why Verbose mode helps me keep the [otherwise-hidden] scrolling continuing to completion and the desktop. Any illuminations would be welcome.

well I unpatched to get smaller update OTA as usual and that has put me back at a log in loop with no safe mode accessible either I’m going to download full installer and give that a go looks like I’m the first one to fail . Suppose you shouldn’t unpatch first ?.

All that mess with preliminary unpatching seems to me far-fetched. Is that really big problem to download 11 gigabytes?

mess ? it’s literally one extra reboot .

Hi @borp99 For problems similar to what you have described, one of the Geniuses who could provide you with an explanation and / or help I think may be the Great @Ausdauersportler

I supposed it's not about one more reboot only.

 

[TOM1211]

I supposed it's not about one more reboot only.

Never had a problem running it before done it for every update so only fail is back to log in loop still it’s feedback so no one else try’s it or at least knows they might get a loop . Why download 11gb if you don’t have to ? . I rebooted once to log in loop then just using micropatcher to overwrite it anyway.
Update : after going back to 12.4 over the top of 12.5 again (only because I hadn’t downloaded the 12.5) to fix log in loop then going to 12.5.1 works perfectly still with all data intact .

Hello to all,

Monterey 12.5.1 installed OTA via OCLP 0.4.11(n) on late 2012 iMac 13,2 27 inch, 1 TB fusion drive, with Kepler NVIDIA GeForce GTX 680MX 2 GB. No apparent issues noted.
Photos, Gimp, Blender and Maps function as expected.

Great work by developers, thank you.

Surely I am not great and unfortunately I have no real idea, it just reminds me of the problems we had before SurPlus came into play to solve the race condition happened during boot with Big Sur last year…

Verbose booting adds some time delays due to screen output to the complete boot process and can hide such race conditions. But the MacPro5,1 is a difficult animal for another reason: it is modular and can have a lot of hardware added causing trouble like boot failures.

 

[MacRumors3590]

I updated all my Mac's with 12.5.1 OTA via OCLP 0.4.10 with no issues.
Thanks everyone!

Also, no issues with my MacPro5,1 machines as well.

 

[MacPeasant123]

Like most others, I can also report that I had no trouble updating the following Macs to Monterey 12.5.1 over the air with OCLP 0.4.10:

MacBookPro8,1
MacBookPro11,1

With my 2011 MacBookPro8,1 -- it was a bit slow after bootup, so I turned off the extra animations and turned off Spotlight, and now it's fine at bootup! In place of Spotlight, I use EasyFind.

Thank you to the developers!

That NVIDIA Kepler fix is really keen! I was finally able to update my mid-2012 unibody 15" MacBook Pro from Mac OS Monterey 12.4 to 12.5.1! But I still don't plan to install Ventura on it this autumn.

OTA update failed on my iMac13,1 as well. After 4 or 5 hours, the installation process just stopped. The external USD HDD has an activity indicator and there was no activity for over an hour. Did not attempt to unpatch.
Used a USB installer that had been created before trying OTA and applied the Post Install Root Patch. No obvious problems.

 

[Larsvonhier]

Success also on MacBook Pro 4,1 (2008, C2D, 17" glossy screen) with macOS 12.5.1 and OCLP 0.4.10, patch for Nvidia Tesla still holds.
(As others reported, Mac Pro 3,1 with Kepler patch also still functional).

 

[esculapio1]

New SSD so nothing installed on the machine.
But I also tried with the old HD with El Capitan and the same happens.
Same thing also happens when I try to install Catalina with dosdude1's Catalina Patcher.
The computer just keeps booting over and over into Recovery Mode regardless of which volume is selected at Startup Manager.

It sounds like Infinite Recovery OS Booting listed here is what's happening? (https://dortania.github.io/OpenCore-Legacy-Patcher/TROUBLESHOOTING.html#infinite-recovery-os-booting)
But if that's the case I don't really understand the instructions to fix. If I uninstall OpenCore from the USB I get the No Access sign at startup.

Thanks

HI,
Did you ever hear what those instructions meant?
I could install Monterey 12.3 and update to 12.4 but when I tried OCLP 4.9 I could not boot from USB or SSD.
I tried resetting NVRAM and different versions of OCLP from 4.5 (which was working before) to 4.10 without success. I keep getting the recovery OS boot screen.
I could install 12.3 and update to 12.4 in a 2012 mac mini and and a 2008 macbook unibody.

No problems with Monterey 12.5.1 and OCLP 0.4.10, on a MacBookPro11,3: BTW, is there a way to enable auto-patching even if you didn’t install the system with an USB flash drive created with OCLP (for example, originally I installed it with an “ordinary” drive, created with the usual Terminal commands)…? Otherwise, one must of course start up in safe mode and manually do the root patching…

Create a new USB installer with OCLP latest and install the very same version of Monterey on top of the existing one.

This should preserve your data while installing and activating the auto installer at the same time.

Disclaimer: Never did this on my own, just a guess.

 

[Sven G]

^^^ Yes, this indeed seems to be the way to go: thanks…

Come on.

Config iMac: iMac 27" Mid 2011 - i7 - 3.4GHz - Nvidia GTX 770M by nikey22 - macOS Catalina - SSD 240GB + HD 1TB - 16GB RAM.

1 - I installed Monterrey, according to the script.
2 - Installed Montrey on the internal SSD.
3 - I restarted the iMac in safe mode.
4 - I applied the patcher with the default options without changing any settings in OCLP.
5 - I restarted the machine and it is in loop.

It turns out that even now trying to get into safe mode, I can't and the progress bar doesn't advance.

I would be pleased if you can install any version of macOS Monterey.

There is definitely some incompatibility with the flashed Nvidia GTX770M. It has it anyway.

1 - OCLP 0.4.10 + macOS 12.5, boot into safe mode, apply patches and on restart iMac12.2 loops.

I looked for some case where the user has the same GPU as mine and I couldn't find it.

After applying the patcher and entering the loop I can no longer enter safe mode.

Any good people who can show me some other way to try to solve this?

Thanks

OBS:
I just installed it again and the images are there to show that I was able to install. But after applying the patcher in safe mode and unable to start macOS Monterey.

Which vBIOS version do you have installed? Does this version support brightness control on your system?
If not check back on the iMac GPU thread in case you missed the vBIOS update posted more than a year ago.

Macbook Pro rMBP 10,1 mid 2012 and Macbook Air 3,2 2010 updated to
Monterey 12.5.1 via OCLP 0.4.10. No obvious issues so far.

Hello all,
Macbook Pro 9,1 mid 2012 updated to
Monterey 12.5.1(21G83) via OCLP 0.4.10. Everything runs smoothly. Kudos and many, many thanks to khronokernel and "crew"

Hello to all,

MacBook Pro 5,2 (mid 2009) 17" 3.06 GHz C2D, 1TB Evo SSD, 8 GB of RAM

Updated to 12.5.1 OTA (build 21G83) with OCLP 0.4.11n. No issues other than Maps app., which requires Metal GPU and hence is not usable.

SSD is divided into 3 partitions; one holds bootable Monterey 12.5.1, the other two partitions hold latest Big Sur, and Catalina installations respectively. Catalina runs via Dosdude1's patcher.

I already reported successful installation of Monterey 12.5.1 on iMac 13,2. A second partition on the iMac's 1TB
fusion drive boots Catalina natively.

Hope this may be of help.

Verbose booting adds some time delays due to screen output to the complete boot process and can hide such race conditions. But the MacPro5,1 is a difficult animal for another reason: it is modular and can have a lot of hardware added causing trouble like boot failures.

Wise and considered words to help steer me. I wonder if OCLP has a setting which can slow the boot process down, rather that my verbose mode work-around? Anyway, it may be timely for me to reflash my Matt Card with the reconstructed ROM done expertly by tsialex, as the ROM chip registers may just be getting a bit full or have conflicting drive cache settings, seeing I boot in and out of 10.6, 10.12 and 12.5 regularly. Starting with a clean slate may give me a better rate of successful Monterey boots - seeing few, if any, other 5,1 users have reported boot problems (baring the boot loop issue which I haven't experienced).
[Update] I reflashed my ROM chip but am still getting boot stalls at about the 1/3rd way point. I'll add -v to my OCLP boot string until a better solution comes along. I'm still incredibly grateful to have my 5,1 running so well on the latest OS.
