Just installed 12.0.1 Monterey on late 2011 MBP. Ran legacy patcher a few times, however I am unable to adjust brightness? Terminal commands, keys, and system preferences are all unable to adjust brightness. Logo stays lit when I close the lid as well. Slowly making my way through the thread, but any advice?
Got a tip for us?

Hi to All!
I updated my CMP 3.1 (Early 2008) from 12.1 Beta1 to 12.1 Beta2 by delta updates after unpatch system volume ( keppler support). After run postinstall system volume patch for kepplers GPU support.
Without issues in install and postinstall.
OCLP - 0.3.2NB (+Monterand - requiered for run 12.1 beta1)
Thank you guys!!!

Out of curiosity: What's the performance like on this one? Do you have any read/write speed results by any chance?
Instead of crawling through hundreds of pages here you might change your strategy and read the OCLP online docs. There is a section about post install patching and legacy video acceleration and trouble shooting, too.
12.1 Beta 2 (21C5031d) installed OTA on iMac 13,1. No significant problems, although microphone is still not working in Safari. Works properly in the Edge browser, suggesting this is a Safari issue not a hardware problem.
No noticeable performance differences observed here, but I don't run any empirical benchmark tests so take that for what it's worth. You will have to apply the OCLP option 3 post install patch after your system comes up in "tiny" mode. This will enable the internal Intel HD4000 GPU and disable SIP
Thanks - the thing is I don't get any slow downs or anything all working fine (except sidecar but I didnt have that natively) it just pops up every time on bootYou can also disable the FeatureUnlock extension completely.
FeatureUnlock causing extreme slowdowns and halts · Issue #564 · dortania/OpenCore-Legacy-Patcher
As reported and tested with Monkiey#3060 on Discord, it's been found that FeatureUnlock can create OS instability for some users even in short periods of time. There is potentially a link between l...github.com
Please: You might finally add a signature to your account like my own. So we know all the time the hardware we are talking about.
I wouldn't expect any performance increase for older machines or added features from now on, probably just cosmetic changes which may lead to slow performance.
I have a MBP5,2 Early/Mid 2009 (see signature) and have recently tested both Big Sur and Monterey on the machine (see this post). Latest updates to that:
- FileVault 2 can be used as long as you don't APFS-patch your machine's ROM.
- Keyboard backlight doesn't work out of the box on both Big Sur and Monterey, but can be made working using Touché.
- OCLP-related discussion on re-enabling Instant GPU Switching between the internal nVidia GeForce 9400M and the discrete nVidia GeForce 9600M GT is in GitHub issues 514, 584 and 717.
- If you happen to have the nanoTECH USB ExpressCard/34, it'll work on both Big Sur and Monterey 12.0.1, but apparently not on Monterey 12.1beta.
- OTA updates work (so far) on both Big Sur and Monterey.
PROs of Monterey:*
- Estimated 3 years of security updates vs. 2 remaining years for Big Sur (okay, how can such a ridiculously short OS lifecycle be a PRO, but that's another story …
)
CONTRAs of Monterey:*
- Wi-Fi is not working out of the box, but needs drivers installed by OCLP's root volume patch. You still can't connect to a Wi-Fi SSID through the Finder bar Wi-Fi icon, as there won't be a password dialog, but have to add SSID and password in the system preferences first.
- As the latest Apple OS, it's probably still undergoing more changes than Big Sur and is thus more prone to problems with future updates on unsupported machines like ours.
- Support for the nanoTECH card in macOS 12.1+ is questionable, see above.
As far as the performance is concerned, my very subjective impression is that it's very decent - I only miss more speed on web browsing while sharing my screen via Zoom Screen Sharing (but only then), on compiling brew formulas from source and perhaps on editing and rendering video. But other than that I really don't miss anything and with these recent OSs, I deem my machine absolutely suitable for another three years.

Hello,
I have a Macbook11,3 running Monterey via OCLP 0.3, with a 64Gb partition dedicated to Windows. Although I had some problems installing all the stuff, now everything works great, thankfully
My question is: I would like to have Parallels 17 to detect and use my Windows partition as if was installed through the Bootcamp Assistant, but I can't find any way to do that – Parallels simply doesn't offer any way to do that. I suppose Parallels can't find the installed Windows because it is not an "official" Bootcamp partition, but does someone know how can I make Parallels detect and use that partition? Thank you.

My 2012 mini definitely performed better under Big Sur while unsupported than it did on Catalina (the last supported OS). So far Monterey behaves much like Big Sur in terms of performance even with the inclusion of the additional features.
Hi. I have upgraded my old MacBookPro5,3 to Monterrey 12.0.1 with OCLP 0.3.1. It worked fine but, when I apply the GPU patcher in the post process, when I log again it starts booting and suddenly goes black and never returns. I hear the hard drive spinning/ working for a while and then it stops doing anything. If I don't apply the patcher it works but really slow as it doesn't have any GPU acceleration. The patcher is suppose to be for this computer but it doesn't work ( at least for me ). Maybe this patcher is not really ready for Monterrey and the MacBookPro5,3... Any idea how to solve this? Thank you.
EDITED: For any strange reason, pressing the brightness control made the system to get back and work again... Bizarre.

I had this on my MacBookPro5,2, too. You can simply apply the workaround here and install today's OCLP 0.3.2 TUI nightly afterwards:
- Boot your MacBookPro5,3 until its screen turns black.
- Wait a bit and press the arrow keys - if they return a sound, the MBP has probably successfully completed the boot process and the display is just dimmed to 0 %.
- If you've successfully passed step 2, close the lid of your MacBookPro5,3 and wait about one minute, until the MBP's fan shuts down and the activity light begins pulsating. Once that has happened, open the lid again and press a key. That should switch on the display again.
Thank you, I will try what you propose. Anyway after rebooting the system once before enabling SIP again, I have kernel panics all the time. SO, I will have to reinstall again and let SIP disable, I'm afraid.
Well, Monterey is installed on an external SSD, so R/W performance is limited by the USB2 connection. That said, the boot lasts 100-120 secs, the disk performance is among 30-35 MB/s in both directions, system apps run after 2-3 bounces, heavy commercial apps (like onlyoffice) could require up to 15 bounces (first run) to 5 bounces (subsequent runs). For sure slow to use as daily driver, but not so bad IMO, basically we are talking about a 13 year old friend...
Hi, could you please share your experience with Monterey on your late 2012 mini? So far, you are the only person I've seen reporting anything about that machine on Monterey, and I've been searching for over a week.
I'm basically interested in Wifi, Bluetooth, AirPlay-related issues, as those seem to be the biggest pitfalls. But feel free to include any other advice about things you've encountered.
Thanks.

Hi,
I will share my proof of concept
I have installed Monterey in my MacBook Air early 2014 , simply copying the installed OS from another supported Mac and modifing Platformsupport.plist with my Mac data.
Easy and fast : all the hW is ok
My only question is what will happen when an update it will release ...
Cheers

Nothing! You would have to go through the same procedure, again! This is a nice method to get a new macOS running unless Apple drops some drivers your system is relying on. So it buys you some time.
