Hi guys, I have an iMac 21.5 mid 2011, can it be updated to Monterey without any issue? Or do i need to update hardware (i already put an ssd inside and more ram ) ?

The best thing you can do is upgrading your iMac with a metal AMD GPU - than you would get a fully supported system. Using the old ATI 6xxx card you can have patches with OCLP, but you will face some or more glitches and some apps will simply not work any longer. Check the OCLP docs. Link on first post of this thread.

thanks for replying. Tomorrow i'll try with patches, i don't care about glitches on apps, actually that mac is used only for web browsing and netflix.

If anyone here can help I would be very grateful.
For the MacBook Pro I can't get to the command line prompt as per "khronokernel". I need to figure out how to get to:
  1. Boot macOS in Single User Mode
    • Press Cmd+S in OpenCore's menu when you turn the Mac on.
When I start up I select the EFI but it doesn't go to the terminal screen. I start the computer holding down Cmd+S, I see the "picker" selection for internal SSD, USB MAC OS install and the EFI.

Best regards

Upgraded my Big Sur installation via software update and OCLP 0.3.1 to Monterey on my mid-2012 cMBP.

Seems to run mostly fine, but there is something weird about the graphics, it feels like it crashes to frame buffer when the HD4000 is put under any kind of strain. The graphics parts of geekbench locked up the computer completely, forcing a hard reboot, but basically, any kind of heavy load on the gpu will randomly make it run like an unpatched system until i reboot.

Dunno, I'll run it a while, maybe do a fresh reinstall instead, but I have a feeling I'll be back to Big Sur soon. That ran beautifully, felt like a native install too.

Thanks for the update. I was contemplating of installing Monterey last night on these Mid 2012 machines, but my experience with the OC patcher on an early 2011 MBP left a lot to be desired and reverted back to Mojave.

The good thing about Big Sur is that we will still receive security updates for a while and a perfectly fine macOS release IMO.
 
DaKKs said:
Yes, even tried the nightly (0.3.2). It has full graphics acceleration, the HD4000 is recognised correctly too.

Except when you push it, it definitely crashes back to framebuffer. Acts exactly like it does before you run the post install patches.

A reboot fixes it until the next time it happens. Its wierd. I'm gonna try a clean install tomorrow maybe something interferes with the patch since i upgraded from Big Sur, which has native HD4000 support.

I think this is really worth opening an issue on the OCLP Github page. Most developers have access to HD4000 systems and getting a crash using Geekbench5 looks (promising) like one can force it. We like reproducibility:)

You need to boot to safe mode and install the post-install root volume patches for Nvidia Kepler. Power off the machine. Hold shift during boot. This should get you past the boot screen hang and to desktop. Using the OCLP TUI version, select option 3 from the main menu (the one that says "post-install root volume patch" or similar) and follow the prompts.

Edit: And keep in mind you will need to do this every update. Since it's kind of a pain in the butt, I would recommend discontinuing the beta/dev track now that Monterey is GA :) So that you don't have to do it as often.

Thanks for the reply and info! To clarify, I need to install as I have been doing, get to the hang section. Reboot but hold Shift this time to access desktop then follow your instructions regarding the post volume patch?

Is it safe just to run the EFI from boot picker, then log in as normal and update from the Software update screen to OS12 in settings? I noticed it earlier but wasn't sure if this was a good way to do it
 
5,1 users, when you upgraded to Monterey did you use OCLP 0.3.1? Thinking about upgrading a 5,1 with stock Mojave..

Shift during boot and then the post install patches fixed my issue as well, I suspected the hang had something to do with the Nvidia card.

I got it to work on 2012 nonretina macbook pro with one issue. It always goes to the Picker during boot even if there is only one drive to select. I used the GUI version of OCLP so I am asking how to get to the menu selections so I can change the setting to turn off the Picker. All I can see to do with GUI v0.3.1 is build open core on a selected drive. I know this is an easy question but it has me stumped.

Thank you

Awesome! it worked on my iMac-running smooth after downloading the full offline version, running OCLP 0.3.1, and running the patcher. Thank you very much. For the MacBook Pro I can't get to the command line prompt as per "khronokernel. I need to figure out how to get to:
  1. Boot macOS in Single User Mode

In case no one answered this query: After booting up with the OCLP EFI, select the target volume, in this case, Monterey, then press Cmd+S, release the keys, then hit Enter.

P.S. Press the Spacebar after EFI boot up will provide some extra icons including reset NVRAM.

Yea let it hang then forced reboot then choose the EFI USB then the internal hd while holding shift..when it boots everything will be pretty tiny text wise.

Sweet thanks, going to give it a go tomorrow. Lost too much time today restoring, installing over and over ?

So I managed to get Monterey installed on my cMP 5,1 using CDF's guide, including Hybridization, SurPlus, etc, as mentioned in his guide. almost everything seems to be working fine, including Bluetooth/Wifi because I have an upgraded BT/Wifi card.

However, one thing is not quite right, hoping someone here will know the work around for it. Its related to one USB2 midi controller, which doesn't work unless I have it plugged into an external USB2/3 powered hub. If I plug the midi controller directly into USB on the back of the 5,1, it is not detected at all by Monterey (I had this problem when I tried BigSur briefly in the past also)

Other USB2 devices are plugged into the front and back of the 5,1, and they are all working fine, only this midi controller doesn't seem to be detected, but yet it does come up detected and functional if I plug it into an external hub.

So.. Two questions,

  1. does anyone know Why this is happening
  2. Is there any kind of work around, perhaps kext injection or something that will get the built in USB ports working 100%?
 
As with every version or cofiguration of OCLP the Screenshot app UI vanishes with NVIDIA root patching, other than very slow-to-connect to Apple B/T devices 0CLP_032 is approaching Big Sur performance in Monterey. ;)

Sort of successfully installed on my MacPro5,1

I am having a problem. First off, I downloaded 12.0.1 FINAL from the python script, and it instead installed the beta build 21A5552a. Not really sure why it downloaded the totally wrong OS but whatever.
It's installed, and I removed the developer profile.. No updates available. I though okay, I should probably run OCLP post-install. I do this, and it tells me to disable SIP. That took me about 3 hours getting pissed until I figured out I had to rebuild OpenCore to be set to disable SIP. I did that, ran the post install patches.. Still not OTA updates.
So, I thought the whole point of using OC in the first place was to get updates?

Well, the installation has been successful on my 2012 15" unibody MacBook Pro!

I even configured the system using the OpenCore patcher to boot without need of the thumb drive and to automatically go right into my Monterey install! Now to update iMovie, GarageBand and the Pro Apps...

Today was upgrade day, plus I got to test out a few things. Now on 12.0.1 on the rMBP mid 2012 production SSD and external SSD. No issues. Downloaded the full InstallAssistant package using the link on Mr Macintosh's site, thanks Mr Mac!

Installed to the external SSD first to test the installer and grok the workflow. I first tried installing "over the top" of Big Sur. It didn't work so I erased the ext drive and did a clean install. When the system came up I used Migration Assistant to copy the user data from the internal drive. Installed OCLP 3.1 options 1-2-3, reboot, done.

Did a Time Machine backup of the internal drive, booted to the just-reinstalled external SSD and erased the production internal drive, a scary moment. But with two fresh backups (ext SSD & TM) , and the experience gained with the external install, risk level was acceptable.

Same process as before, but this time I restored the user data from the Time Machine backup on the Synology NAS. Worked.

Thanks to everyone here and in particular the OCLP devs. I learned a lot and am looking forward to taking a break from beta testing until the next one.

I should report on how my Monterey 12 upgrade went with my Mac Pro 5,1. (You can see my specs in my signature block and attachment below--2012 Westmere Dual processor system--LOVE this thing!)

Initially had a micropatcher install of Big Sur 11.2.3 (no OC), as it was just easier to boot directly from the macOS screen. I physically took the WiFi and Bluetooth modules out of my Mac Pro, as I wasn't using either and upgraded to a Broadcom Bluetooth 4.0 USB dongle which worked just fine. (I use Ethernet for Internet connectivity.) I was able to install 11.4 without Latebloom (don't know how), but eventually the infamous racing issue started off and on once trying to upgrade to 11.6. (I had to disconnect external devices during boot just to get it to work--worked 80% of the time.)

Because of this, I decided to create a new installation for Big Sur 11.6 using Opencore 0.7.4 along with the SurPlus fix for the infamous racing issue. I nuked two hard drives clean for the install and followed the instructions to a T. It installed without a hitch on my system, and Big Sur 11.6 launched everything as expected... OC is a lifesaver and is buttery smooth! Can't believe I didn't do this sooner. Then decided to take the Monterey 12.0.1 plunge with Software Update.

Everything installed as expected, and my system booted up within an hour after a few standard restarts. Comes up like a charm! I didn't run into any random restart issues or hangs, but also, I did the upgrade on a clean install of macOS Big Sur... might be worth considering.

Personal Note: If you have a separate hard drive: Consider moving your user folder to that drive. 10x easier to move your stuff, AND your settings stay intact.

Issues:
- I've experienced issues with my login screen being off-center on my 4K UltraWide Monitor.
- I also have no BT support, but I believe an OpenCore config.plist and maybe a few kexts can fix this... I just need to find the configurations. (Please point me in the right direction, if you know of one.)
- I have no AirDrop or casting ability to my HomePod mini because of missing Bluetooth. All of these worked on Big Sur.

Hope this helps someone! Good luck. :)

I am using Mid-2009 MBP(5,5) with Big Sur 11.6 and OCLP v.0.3.1.
I would like to install Monterey 12.0.1 into my MBP with OCLP v.0.3.1.
I want to know if it can actually be used.
