I have a 2012 5,1 on Mojave (see pics for specs), & Ive downloaded Unreal engine 4 which is supposed to run on Mojave, but I get an error message saying I need xcode...I was under the impression it was part of Mac OS? It seems I need to download it - where can I get the version that will run...

Hey everyone, I've quietly observed this forum for the last year while diving into the world of OLCP and Hackintosh. I have spent countless hours trying to get a successful install with Sonoma 14.1.2 on one of my CMP's. I was able to get it to work successfully ONCE, but despite scouring forums...

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...

Mac Pro 4,1/5,1 may have been zapped by a power surge. No response from machine when pressing power button. Tried known good PSU, and the only sound I hear is a click when I plug in the power chord. No blinking lights, no LEDs on CPU tray. Pressing the LED test on mainboard shows the standby...

I’m trying to get Windows 11 installed on my cMP running Monterey with Martin Lo’s OC and I’m stuck with an error saying ”Windows 11 installer couldn’t create a new partition or locate an existing one” when I’m choosing the drive to install to. I’ve tried formatting the drive but it won’t fix...

Posting this in case useful to others. Reading the HP manual (!) I found connecting the USB B end (square plug) of the cable to the HP monitor and the USB A end to the mac, Mac OS automatically detected the monitor webcam. I can use (have tested) the 720p webcam in Teams and OBS studio.

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...

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...

I'm using two DisplayPort cables but i cant get past 3840x2160. The Mac Pro specs are the following: 4.1 flashed to 5.1 latest bootROM Dual Xeons E5520 128gb RAM ECC XFX AMD Radeon RX5700XT 8gb Triple Ventilation OWC Accelsior M2 with a Crucial P3 1Tb I'm running Catalina with all the...

Hi all, Specs: cMP 4,1/5,1 Monterey 12.6.1 on SATA SSD WIN10 on dumb NVME PCI-e adapter OCLP 0.5.1 Sapphire Pulse RX6600XT LED Cinema Display 24" (A1267) After flashing the 6600 and installing it in the cMP, I cannot see the OCLP boot picker. OCLP is working since the cMP boots into Monterey...

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...

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?)...

OCLP 0.4.3 and Monterey OtA 12.3.1 update ran and rebooted the machine. After that, boot screen shows, progress bar gets to about 50% and stops. Hard powered off. Powered on again, startup chime, but nothing on screen. Hard powered off. Powered on again, progress bar to 50%, let it sit for about...

My cMP is running RefindPlus > OpenCore and I have Legacy Windows 11 installed on a separate SSD in one of the SATA II bays. I successfully upgraded from Windows 10 to Windows 11, and it boots beautifully from the RefindPlus boot screen. I have Parallels 17.1.1 installed and was able to run...

Out of nowhere i’ve been experiencing my GPU drivers crashing on the Mojave and Windows sides. Originally I was running an RX 580, then tried switching back to my EFI 7970, which helped a lot in terms of graphical glitches but still constantly crashes the driver. On macOS the rest of the system...

Hi guys, got a cMP 1.1 for peanuts. It was working decently (and by decently I mean astonishingly fast for a 15 yo computer), booted in 10 seconds, overall workflow was great & snappy. I wouldn't be myself, if I wouldn't try to make things better, so I took an SSD laying around (it was working...

I was encouraged to share my experience with installing macOS Big Sur on two of my cMPs as I wasn't able to find anything already prescribed for those like me who use the RefindPlus/OpenCore Chainloader, and hopefully it covers off some useful information for others attempting the same. I have...

Hello everyone, I bought a used cMP, which was sold as 5,1 (not working). I have a working 5,1 to swap parts with the broken one. PSU, Processor Board including CPU & RAM, Bluetooth Module, Disk Drives, Hard Drives, GPU and everything works when swapping, except for the Logic Board. The...

Made a video detailing how I installed Mojave onto my 5,1 CMP:
