    First off, I want to say that I'm glad to be back here on the forums. Thank you to the admin who reactivated my account. It's been two years since I started my original CMP journey, documented here on the forums of course. I sold that computer shortly after my modifications because I was fed up...

    Hey everyone, I've quietly observed this forum for the last year while diving into the world of OLCP and Hackintosh.

    I have a 2009 cMP 4.1 --> 5.1 computer. I followed the information here and started with Macschrauber's Rom Dump. Then did the EnableGOP ROM mod to get the Native Bootpicker on my RX 460 graphics card. Finally, used the latest OCLP to make a Monterey USB and install it onto a new sata SSD. I...

    Hello everyone, I have a question about cMP + EVGA PowerLink. Yes, I understand, I've done my research and indeed found many recommendations. However, one thing still isn't clear to me. I noticed that many demonstrations simply connect the two mini power supplies from the motherboard to the...

    Installed Windows 10 on cMP and am puzzled by file transfer

    I bought a new camera and my old Mac Pro 4,1>5,1 can't access the raw files. I had a few options but decided that the simplest solution was to install Windows on a separate SATA SSD. I did that this afternoon, installed apps that I needed Windows for and it works well. I never worked with...

    Curious as to whether the position of HD/SSD sleds makes any difference between slots one, two, three or four? The presence of a non-bootable—and also unrecognised 8TB HD—in the left-most position, on start-up appeared to prevent the machine from advancing beyond the chime, despite the presence...

    Hi all, my trusty 4,1 (flashed to 5,1) all of a sudden just shut down without being under load and wouldn't properly start up anymore. After it cooled off, it will boot again, but within 5 minutes or so before it just shuts down again. I read the threads about the temperature issues and cleaned...

    MP 1,1-5,1 Mac Pro 4,1 and a 5th PCI-E connector?

    The airport connector looks like a mini PCI-E connector and it got me thinking has anyone equipped this port with anything other than a wifi/bt card? It may lack a +5V or +12V power pin as there are separate wires for the airport card (which include the antenna, but one of them is for power?)...
