macOS 12 Monterey on Unsupported Macs Thread

[iMac-Oldschool]

After a few days/weeks with 12.0.1: Everything is running fine except for Safari, which is acting up. Stops loading pages or content, only loads it half, buttons not clickable. That browser is not ready for prime time at all. No issues with Firefox on the other hand.

Similar problems with Safari on an iMac 13,1 late 2012. Buttons do no work and neither does the microphone. Microsoft Edge does not have either problem and the microphone works properly in Zoom. (Hope that the reference to Edge does not get me banned from the Forum.)

If you used RAID-0 you'd know it's an advantage, everything opens faster when it's in RAID-0, referring to macOS Catalina, it is possible to install and update but the installer must be prepared with micropatcher, even you can install macOS Big Sur in RAID-0 using the old micropatcher, as it creates a layer that is able to skip the check and install to disk.

So - to get this back on topic ? - it is possible to install macOS Catalina on RAID 0 and macOS Big Sur,… any success with macOS Monterey?

Does anybody know the background of the OpenCore Legacy Patcher 0.2.5 changelog entry on FileVault 2?

Allow Root Volume Patched Systems to use FileVault 2

• Requires macOS 11.3 (20E232) or newer

I've tested activating FileVault 2 on my root volume OCLP-patched MacBookPro5,2 on both macOS 11.6 Big Sur and macOS 12.0.1 Monterey without success. An active FileVault 2 would render the system unbootable immediately.

I also was under the impression that FileVault 2 use would be forever impossible on root volume patched systems. Do I misunderstand something here? - Thanks!

@Ausdauersportler that did the trick thanks!

I'm trying to do the install on my macbook pro 15"retina (macbookpro11,3) That was ok till Big Sur.
The install looks ok, till it's nearly finished. It stops at the black screen with the Apple logo en the progressbar at 40% Then a voiceover voice is heart (?!)

Anyone with the same issue?

Yes, same exact issue with same machine. Did you get it to work?

I am considering doing the patch for Big Sur on my late 2011 MacBook Pro, since the Catalina patch works so well. However if there is a working patch for Monteray, might as well go that route.....

Onyx/Maintenance runs fine but doesn't do much compared to previous.

I've been running Monterey 12.0.1 on my late 2012 Mac mini for a while now and everything is working perfectly, even Safari, after performing an OTA update from Big Sur. Something that has me excited is how well AirPlay (receiver) is working on this machine. That has got me thinking about trying to enable it on one of my late 2014 minis. Is there any chance that OCLP will unlock that feature on one of those machines (either by just installing OCLP on the EFI partition or doing a reinstall of the OS) even though they still natively support Monterey?

is it possible to instal 12.1. beta on other through USB connected clear disk starting Instal macOS Monterey beta exactly from Application directory? Or it is necessary to do only from created setup disk?

Ive done both and it works great but remember you need the correct OC for this to work on unsupported Macs.
I use OCLP 0.3.2 Nightly build.

Thanks, both of you.

It may be possible. Make sure you shrink the existing partition and create a new 16GB FAT32 partition (not container) for installing the Monterey installation media. You can also just install the OCLP to your internal EFI (a 209.7MB volume at the 1st of your disk partition & volume, normally shown as disk0s1) and use OTA update to install Monterey. In this case, you don't need to modify any partition.

Hmm, you may install OpenCore through OCLP onto the (still existing but invisible) EFI partition of your current internal disk, reboot through OpenCore into your current macOS version and try a software update...
You may backup your data using TM or other tools before starting the update.

So, what I ended up doing is I removed a bunch of APFS snapshots, after which Disk Utility let me shrink the APFS container, put the installer on the FAT32 partition and OCLP on the internal EFI partition, rebooted (which let me select OCLP) and launched the macOS Installer.

I'm having a weird Monterey upgrade issue on my Mac Pro 5,1 with Martin Lo's 0.7.5 OC package. I'm running 11.6, the update package appears in system prefs, it downloaded successfully, runs the upgrade process then reboots with no errors or problems, but I find myself back in 11.6 exactly as if the update had never happened. Did I miss something?

I watched this more carefully. After finishing the install run, it reboots with the startup volume set to a volume I've not seen before called "PreBoot". That boots, shows the Apple logo and a progress bar, which gets about 1/3 of the way across before rebooting again, with the startup volume set to my normal boot volume.

I had several attempts at booting repeatedly from the PreBoot volume, but it always acted the same way, and so I'm still stuck on 11.6. FWIW, I'm booting from a PCIe NVME card with OC installed on a separate SATA SSD. My upgrades from 11.2.3 to 11.3, and on to 11.6 all worked fine previously.

Any bright ideas?

You don't have eye strain while using Big Sur/Monterey on your 14,2? I do, to the point where it is unfortunately unusable but for some reason it doesn't happen on Catalina and below. I've tried every patcher there is and no matter what, I cannot look at the screen for too long while using Monterey or Big Sur without my eyes hurting. I'm really trying to get to the bottom of it.

I’m having the problem also. Did you ever find a solution? Any version higher than Catalina causes this issue. Any any version of Safari higher than 13 does as well (even on Catalina).

Does Maps work in Monterey on unsupported machines? I mean it works, but the map view is totally white, which renders it useless. In Big Sur the map area displayed on this 2011 MBP. I can't edit widgets either.

Excuse me, sir. I have the Macbook Pro 8,3. You mean you have Big Sur running? With no artifacts and working everything right? I have tried many times but the graphics don´t work very good. Thanks.

 

[tripmusic]

I was only on it briefly. I wanted to see how it compared to Monterey. I'm almost certain that I could see the map area in Maps. Obviously with the limitations of no METAL GPU. Overall though, the usability and artifacts of the OS itself were about the same as Monterey, so I switched back to that. I'm just testing it out on a separate partition. I'll probably go back to Mojave, as it's just less buggy. Most of the artifacts are in Finder windows and the Menu Bar, but not a total mess.

I guess the ending of our beloved Macbooks Pro 2011 is near. At least, we have full Catalina support one year more.

I have just bought a 2014 Macbook Pro 15", beginning the transition. I know, 1,6 inches less, but it´s the best I can think of.

Dear Friends, Developers !

Short feedback from my side after yesterday, installing Monterey 12.0.1 on my devices :

iMac 18,3 ; native as benchmark or compare

MacMini 6,1; OCLP - Mac used as Media/File server. Installation went without any troubles, after post-installation patching works absolutely everything ! Im using all my devices (even supported) with Reduced Transparency and Reduces Motion since i don't need this fancy stuff and i find them only as wasting HW resources. Only manual work was replacing the EFI and configuring the EFI boot to hide OpenPicker since using Post-patcher remain this unchanged and Picker was showing even if was marked as hide. As i mentioned, i use this device as Server - Sharing, VPN, lot of external USB, FW, Thunderbolt HDDs, some of them locked with FileVault.

MacBook Air 5,1; OCLP - Air used as daily portable device. Installation went without any troubles, after post-installation patching works absolutely everything ! Im using all my devices (even supported) with Reduced Transparency and Reduces Motion since i don't need this fancy stuff and i find them only as wasting HW resources. Only manual work was replacing the EFI and configuring the EFI boot to hide OpenPicker since using Post-patcher remain this unchanged and Picker was showing even if was marked as hide. This machine is officially supported till Catalina. I made a try maybe year ago with BigSur over OCLP. The performance was very bad, the machine was slow, i had several times problems after wake-up with unresponsive device and glitches, also AirPlay was not working correct or abosultely not working. Now with Monterey&OCLP runs the device SMOOTHER as with Catalina ! I really dont know, how is that even possible, but im absolutely satisfied ! ONLY BUG a found is touchpad. Everything works absolutely as it should, but i noticed that i need sometimes "tap" twice since the "first tap" is without respond. I noticed that maybe 5 times since yesterday. Maybe i "Tap" to soft, but i don't think so...

So i would like to say THANK YOU for everybody who spent energy and time to continue developing this tool, my compliments for your knowledges !

Macbook 11,3, 12.1 beta and 3.2 OCLP, post install patch applied but still having full system crashes (numerous per day). Casing get pretty hot to touch and not responsive when left in sleep for a few hours. I've stopped using safari but still issues. The only other issue is trackpad doesnt always register tap to click. No other problems elsewhere. Any help is appreciated!

I have installed the latest OCLP on my mid-2014 15 inch MBP with gt750 and everything seemed to bo working fine. Then I started to realize that my mac never sleeps if it is plugged and I close the lid. Audio will keep playing and popping once in a while like it's trying to make it go to sleep but it can't. So I started testing it, usual suspects, pmset, wake for network/bluetooth/powernap etc. Nothing. It's only happening when plugged in and I close the lid. On battery it goes to sleep and wakes up properly. Also sleep works as I can press the sleep button and it goes to sleep. If I then close the lid, it will wake up and go to sleep again. Strange behavior. Didn't have it on Catalina and Mojave. I thought to myslef, too bad, let's go back to Big Sur which I skipped entirely. Guess what? Same problem. Won't go to sleep by closing the lid when plugged to power. Did a bunch of clean installs to test it without even opening any apps, same thing. Mojave and Catalina behave as expected, tested that 20+ times just to have some clarity that it's not my machine. It seems to me that apple screwed something up for some older machines with Big Sur and then instead of fixing it, they decided to cut it off from to support making Catalina the last fully functioning OS for my mid-2014 MBP with gt750m. Found a bunch of people online saying the same thing. I'm quite pissed as my hackintosh has never given me a problem which I couldn't solve and runs Monterey better than my MBP runs Big Sur.

I have a nanoTECH expresscard with two USB3 ports which I use to connect external disks in a faster way than with the onboard USB2 connectors.

Worked upto Big Sur 11.6.1 (and maybe still Monterey 12.0.1, I forgot).
Doesn't work anymore in 12.1b1: card is detected, but when connecting a USB disk to it, the OS fails in that the pointer of the internal trackpad (connected to internal USB) stops moving.
Will certainly affect very few users, and I could also live without it.

Maybe an effect of the beta software, going to analyse further.

EDIT: a mouse connected to this USB3 works correctly.

I have a nanoTECH expresscard with two USB3 ports which I use to connect SSDs in a faster way than with the onboard USB2 connectors.

That’s unfortunate, I happen to have the same card in a MacBookPro4,1 and really like it for not needing any kernel extensions so far (only tested up to Big Sur 11.5.x beta yet).

I also have some of the 'cheaper' XpressCard34/USB3 but they always needed a driver (kernel extension) present to work. But in Monterey we wouldn’t get any of those to work either, or am I wrong?
