I found my 2009 Mac mini in a box and thought I'd experiment with it. I used Opencore Legacy Patcher to install Monterrey and it worked. However, Wifi didn't work as expected and I also had some graphic issues. So I thought that I'd best revert to stock.
I fetched a El Capitan bootable USB...

I recently tried to do a bootable opencore Monterey install on a fresh ssd installed on my iMac mid 2011. It got all the way to the end of the install but on the final restart I got the message “your computer shut down because of a problem…” and will not go further than that. I did all the...
Hello everyone! I need some help with my cMP 5.1
Bought a 2nd hand XFX Radeon VII, saw it working on the computer it was pulled off from.
Got home, replaced my RX 590 NITRO+ SE with the Radeon VII and got no boot screen on any output port on the GPU.
Plugged back my 590 and everything works as...
Install Windows 10 next to Monterey w/ OCLP, Mac Pro 5,1
I'll try to be to the point:
I have a Mac Pro 5,1 with an RX 6600XT (patched w/ friends PC for boot screen), dual 1TB NVMEs on a single PCIe, one for Monterey and one for extra space. I also have a 1TB SATA disk that I wanted to install...

Good morning..
Macbook Pro Mid 2012, 1TB SSD and 16GB Ram was working wonderfully with open core patcher Monterey..
So.. I stupidly allowed the mac update to Ventura complete, thinking that it will start and I will simply patch it on boot.. Well it no longer boots.
Is there a way to recover...
I installed Monterery using the OpenCore Legacy Patcher 5.1 on a MacBook Pro 2012 (non-retina) that had served its original purpose.
I used that Mac (macOS 12.6.1) for a few days and was presented with the macOS 12.6.1 software update again. I applied that updater with some doubts, and the user...
Hey guys,
I'm in the process of doing some upgrades to my 5,1 cMP. I installed a Sapphire Pulse RX 580 GPU 8GB, firmware updated to 144.0.0.0, clean installed Mojave, and installed Opencore using Martin Lo's package. The GPU works fine but doesn't give me the boot picker. Did some reading on...
I have a scenario where I'd like to flip the default behavior one sees with OpenCore (specifically OpenCore Legacy Patcher) wherein the integrated SATA controller on a MacPro5,1 shows all attached drives internal (aka `built-in`) drives. Note this behavior is defined in the DeviceProperties...
Hello all,
I have here a MacBookPro9,2 (Macbook Pro 13 Mid 2012) with the latest Monterey in version 12.6. Currently I have the problem that I get no signal on my external monitor via MiniDP. I have tested two different adapters. The integrated display goes black briefly and comes back again...
Hello again. I am wondering how I can set OCLP to boot into macOS by default when I power on or restart my Classic Mac Pro. I have macOS Monterey and Windows 10 installed, both on their own SATA SSD drive. When I power on the computer it defaults to the Windows 10 drive/OS unless I choose...
Hello, I’m working on a project my self I have been. I just had throw away my iMac last month becuase I Fried it and I forgot you could buy a new logic board oops. Oh well. Anyways I’m looking at the 2011 and 2010 21” and 27” iMacs and creating an open core package for them just like Martin lo...
Hi,
I successfully downloaded and installed Opencore patcher for Monterey OS.
However, I am unable to boot it my iMac (mid 2011) without the USB - it just runs in a restart loop.
I did the download with the hope that I could finally use my iMac as an external display, as it is not supported...
Greetings all.
I have been searching for the best way to approach a OpenCore Legacy Patcher installation on my Mac Pro 5,1. The scenario is as follows:
I have been running High Sierra up until this point and would really like to go the OpenCore route to gain a boot selection menu with my RX...
I have Monterrey (12.4) running on my iMac 2010 via OpenCore Legacy, and in almost every respect it's running well and is surprisingly quick -- well beyond my expectations! And I don't even have an SSD!
My only problem is that every time the computer wakes from sleep, the mouse is unusably...

Hi there guys!

The reason why i want...
