macOS 12 Monterey on Unsupported Macs Thread

[joevt]

Problem solved! ~ As it turns out, the problem was related to using the 2011 Mini's built-in SD card slot; somehow it was apparently getting deactivated during the boot process, thus taking offline the very installer that was in the process of booting. Attaching the SD card via an external USB card reader solved the problem. (As the 2011 Mini has only USB 2.0 ports—not 3.0—the install was slow… but it worked.)

Exactly which Macmini5,x model do you have?

While in the installer, can you insert an SD cart into the 2011 Mini's built-in SD card slot and see it in Disk Utility.app and read the files in Terminal.app?

Does the 2011 Mini's built-in SD card slot work after Monterey is installed?

Maybe an ioreg would be useful.

I fixed this issue and feel the need to post as it was very weird. I ran the upgrade which duplicated the drive names on boot in oc, and it just kept rebooting after 50% then back into big sur. tried lots of different installs of it.

Then I had enough and wanted to factory reset, I did an sec reset and one of the partitions (in the Mac boot loader) was called Monterey installer. I selected that it went all the way to the end of the progress bar took around 30 mins. then it had a circle with a line through. I rebooted and back in open core I only had one entry now. I ran this, it rebooted once, did it again and I was in all upgraded!

Right... so I've upgraded my 2011 iMac to 12.1 with OpenCore - upgrade went flawlessly...

But... my 2015 MacBook - I am having the same issues and its driving me nuts - downloads the update spends 30 mins preparing - reboots back into 12.0.1. I have tried my fix I used before but I get the struck out circle first time now so I don't know what's happening. has this been tested on a 2015 MacBook? Im really stuck with this I've tried 6 times now...

Cheers

This happens to me with monotonous regularity when installing OTA to an external SSD with 512 GB. I have noted that the current 12.1 is a release candidate, not the final production version. I've decided to wait until the production version is released, maybe next week. Will try OTA first, if that fails will do a clean install.

I have updated my MBP 9,2 mid 2012 non-retina to OTA macOS Monterey 12.1 - 21C51 using OCPL 0.2.5 without a hitch and the process took only 45 min! Everything works perfect and smooth! Thanks to everyone that made this possible. Have a great one!

Prior to 12.1 B (21C5039b), I had VeraCrypt running successfully, for one reason or another, I had to uninstall MacFUSE due to another program uninstall/conflict but now unable to get MacFUSE 4.2.3 with VeraCrypt to keep/register properly their KEXTs with this version of MB. I have a feeling there has been changes to the user kernel space management which is broken - can anyone confirm?

I can state that upgrading to 12.1 (RC) has resolved this issue with user KEXT's not loading/registering correctly. Weird thing is that I was not prompted to re-register the KEXTs as they came over from prior OS version - they just worked!

Getting to 12.1 (RC) was a bit tricky as the OTA from 21C5039b was not advertising upgrade. I installed pre-RC and after that, 12.1 was offered OTA which I took and all is now good.

Looks like they just pushed 12.1 RC2 out the door..

Yup, it's build 21C52, up by 1.

 

[jonnyv34]

ALready updated, it went fine here, MBA 2012.

2014 MacBook Pro 13' went perfect

Mini3,1 to macOS 12.1RC2 OTA atop RC1 via OCLP_031R>032N, install not as smooth as previous but runs as intended, so far. No ghosts, browsers intact, snappy response just like RC1.

Brief, just a simple solution solved my wifi problem: deleting some plist files

Now I need help solving my trackpad pref panel issue. (I need so badly drag files with 3 fingers and tap to click)

and a workaround for hidden bar/vanilla apps, both crashes and hide everything

Yesterday, at around 9 pm European time or 12 noon PST, it was possible to update the HDD attached to my iMac from Monterey Beta4 to 12.1 (21C52). Most apps appear to be working, apart from the microphone in Safari and Sidecar which generated a rather unhelpful "Miscellaneous error." Sidecar has been rather unpredictable under various Monterey Betas, which may be attributable to the very slow performance of the HDD connected via USB2.
This morning, at around 9 am European time, it was not possible to update the internal Fusion drive from 12.0.1 to 12.1. Repeated attempts only gave the message that the system was already up to date. The iMAC was removed from the Beta Program & re-enrolled and the NVRAM reset; neither achieved anything.

Just installing 12.1 (21C52) to an external SSD of MBP5,2, on top of 20C51.

Usually I have to boot via OCLP 0.3.1 to see OTA updates on that machine. So also this time; didn't see 20C52 when booted via 0.3.2 nightly. Going to post-install patch with 0.3.2n.

Black menu bar (and some of your other observations) point to lack of graphics acceleration.
Did you start from Big Sur for this update to Monterey?

If so, have a look at page 1 of this thread, spoiler "Macs potentially capable of being patched to run Monterey".
The iMac14,2 is now in this category. I don't have such a machine, but I'd bet it now needs the Post-Install Volume Patch (3 in the TUI top menu) to get back acceleration.
As far as I know this is available in OCLP 0.3.2 nightlies for your machine. Maybe best to wait until 0.3.2 is released. If you can't wait (e.g. if you did this update to a production machine), try to get hold of a nightly, but using nightlies is always a risk.

Did the Post-Install Volume Patch of 21C52 with 0.3.2n (last commit 9Dec). System works fine.

Apps:
Problems with Safari 15.2 which comes with this 12.1 release candidate: freezing again. Safari 15.1 running fine, and Firefox (now 95.0) as well.

Working fine on Mini3,1. Used OCLP_032N 12/8 7PM.

Additional: Scrolling in Safari not as smooth as Mozilla or the Chromes everything else 100%.

I have some problems with OCLP and Monterey on my Mac mini 6,1.

I did a fresh install of Catalina on the mini, then OCLP 0.31, then upgraded to Big Sur (which worked perfectly fine) and then to Monterey 12.0.1.

Now, while the upgrade to Monterey worked fine, I have lost all graphics acceleration:

I know that Monterey no longer has drivers for the intel HD 4000 iGPU in the Mac mini 6,1 but as far as I understand it OCLP was supposed to fix this?

So how do I get graphics acceleration back?

Check the OCLP online documentation about post install patching (for now a manual step to be taken after each Monterey update, again).

21C52 update on Macpro 3.1 OCLPn 3.1 all ok as usual.....thank's to developer...

Mahlzeit! ?

Argh, for some reason I thought post-install drive patching was only for issues related to the storage medium ?‍♂️

Thank you very much for the kick in the right direction, did the patching and now have gfx acceleration!

Reporting in one final time to say that after two days of booting and rebooting, disabling TRIM definitely solved the long 4-minute startup issue.
Now consistently getting 20-second boot times. Faster than Catalina!

Not at all! They are necessary for some macs. Macbok pro 2014, for instance.

Now consistently getting 2m is still enabled.0-second boot times. Faster than Catalina!

If SATA looks like this, TRIM is still enabled.?

Mine doesn't. I disabled it using sudo trimforce disable, then had to agree to two warning prompts, and a forced reboot. Running great now.
