Thanks for that quick reply!

Could you please recommend me any metal GPU for 2011 27inch iMac? Don't want to spend fortune for it, so cheap option would be which one?

Thanks!
No, check the thread and take your pick and search the local market.
Edit: Get an AMD card, these are still fully supported on Monterey!

Firstly, thank you to the Opencore team, you did great work!

I have most bugs resolved, but still suffering from regular full system crashes? Macbook 11,3

My MBP4,1 17-inch Early 2008 has a PCIe Express 34 card slot, is there an eGPU Metal card that would work in terms of OCLP/Monterey and Applications relying on a metal GPU? What then about SSE4.2? Applications like Photoshop 2021 and higher check for it. Please advise.

Check the builds database at egpu.io

If an app requires SSE4.2, then you need a different app, or you need SSE4.2 emulation that doesn't exist yet but probably should be possible. Actually, I found this thing https://steamcommunity.com/sharedfiles/filedetails/?id=2362590754
It seems in Windows you can add SSE4.2 emulation to specific processes. That would be a nice trick for macOS. It would allow smarter apps to fall back to their non-SSE4.2 methods while dumb apps like Photoshop would get this emulation.
That page goes to here:
https://www.intel.com/content/www/us/en/developer/articles/tool/software-development-emulator.html
It has Mac support!? Maybe. The last version of macOS it mentions is El Capitan. The release notes mentions Big Sur.
https://www.intel.com/content/www/u...tware-development-emulator-release-notes.html
I have not tried it and I don't know if it's applicable to your situation.
 
Check the builds database at egpu.io
Earliest MacBook Pro in the database is 2011. You'll have to search for 2008 elsewhere, but egpu.io may have other useful info.
I googled "egpu" "2008" "MacBook Pro" and found some stuff like this:
But for Nvidia, only Kepler can work with Monterey so you'll want to use AMD to get something more modern?

Thank you joevt, for this as always exceptional help.

I am working through the links you posted and will report back, if I can get it to work.

Awesome, joevt. Thank you!
 
Hy,
First of all, thanks to OPC and OPLP developer teams for the job.
Today, I have an issue to my macmini6.1 (Monterey 12.0.1 - OPLC 0.3.3 patched). There is no OTA for 12.1.
It tried via Installer macOS Monterey on UBS key (OPLC 0.3.3 patched) without success the message "An error occurred loading the update" prompt at 12 minutes of installation stage,
Please could you help me ?
G.
 
Thanks for your work open core team! Installed on my late 2013 iMac yesterday and everything went smooth.

Check the OCLP online docs and troubleshooting section.
Hi, I've read through the OCLP troubleshooting section for "Stuck on This version of Mac OS X is not supported on this platform". On restart, my iMac goes straight to this message and I don't get the option to select anything. The guide says to resolve this ensure you're booting OpenCore before the macOS installer in the boot picker. Any suggestions on how to get the boot picker?

All sorted. Re-ran and I'm now up and running. Thanks for your support :)
 
Hi again,
managed to upgrade to Monterey from Mojave but I have two major issues (so far I hope)
1. Βoot screen shows only boot SSD and a Windows system I have. Recovery and time machine are missing. the OC boot has a small arrow that goes back but it forces mac to restart.
2. Μy 10g Aquantia (ASUS C100C) is not working. Found this

at post #54 a guy manages to fix that by my kext editing knowledge is exactly zero.
thanks on advance

Press Space Bar when OC is loaded.
 
thanks, all icons appeared but both recovery (gives a no signal) and Time Machine do not work.
Did you create the new APFS containing the Monterey installation from the installer disk utility or did you use the Mojave one?
Have you tried to rerun the OCLP TUI and install OpenCore, again?
Did you update from Mojave directly (not really supported)?

There were several reports with TM on Monterey, so it is not clear if it works fully.

thanks for the reply
1. I installed on top of Monterey, no clean install
2. Yes
3. I installed from OC boot

Apple has change the APFS format several times.

As of now I would say your problem is the update coming from Mojave. You can easily cross check this creating a new partition (important, it needs to be an partition) and create a new APFS using the Monterey installers disk utility. After doing the full installation try to access the new Monterey installation and it’s new recovery.
 
Hmmm. Can't remember if I did the spooking prior to building and installing to the EFI. Is there a way to remove what I did previously to the EFI and then redo it correctly. I know I didn't spoof it when I built my original USB. I hope that doesn't mean I have to start from scratch again.
OK. I hate to keep cluttering this thread up, but I went through the entire install process again. Everything went well and the graphics looked great. But when I install the post-volume patch it goes to hell. The transparency is whacky and I have to reduce transparency.

I am fine with that, but there are other errors that drive me nuts. For example, when I open control center the sliders for brightness and volume get all square and pixelated. However, prior to installing the post volume patches, the sliders and transparency all look great. Any idea what I may be doing wrong.

As a refresher, I am trying to update a mid-2011 Mac Mini 5.1 with an HD3000 GPU to Monterey 12.1 with OCLP 0.3.3. I used v0.3.3 with minimal spoofing to build and install OCLP on both the USB installer and the internal UEFI partition.

Welcome to the non-metal OCLP crowd! That's the price you pay for acceleration. Have a look here:

You might as well read a bit more in this thread, probably even more in this one:
What you describe, is well known.
