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...

I am trying to prepare an OpenCore Legacy Patcher (OCLP) installation USB drive for an iMac I don’t currently have access to. I know, it’s an iMac16,2. Would this be the right procedure: Open OpenCore Legacy Patcher app (1.2.1 as of this posting). Click the Settings button and select iMac16,2...

I have 2 ghost drives that only show up in the Open Core option-boot screen, and I want to repair whatever is causing them. If I select them to boot, one loops back to the same screen almost immediately, and the other loops back as soon as you let go of the option key. The two with weird names...

Dear all, I have a Mac Pro 2009 and has multiple bootable disks, main NVME is running Mojave and a other disk is with OCLP Monterey and my goal is making my NVME booting (Clean install I prefer) with Ventura or even better Sonoma. I watched some YT OCLP guides and started that. And what i do I...

I'm wondering if anyone else has experienced this. I was running dosdude's Mojave on it before OCLP & clamshell mode worked fine. But now, with OpenCore Legacy Patcher, it doesn't work any longer. When I close the laptop (15 inch Macbook Pro 2010 6,2) it stays active. Is there a setting I'm...

I have a mid 2010 27 iMac with High Sierra. Due to the hard drive size etc, want to use the machine to keep backups of various things. Delighted to find the OCLP project and subsequently loaded Ventura 13.6 which runs really well. This is my first time with the Mac environment, previously...

How do I sign up for emails notifying me of new OCLP (OpenCore Legacy Patcher) releases?

OpenCore Legacy Patcher (OCLP) 1.0.0 made macOS Sonoma available to many Macs that could run Ventura but had been dropped from the list of supported machines able to run Sonoma. One big exception were several 2017 Mac models with a T1 chip. I just discovered that OCLP 1.1.0 has been out for...

Hello. I have a 2010 Macbook Pro with OCLP 1.1/Monterey. It works great for what I need it for, but I would like to be able to present in Keynote. I know it is a very old machine. The problem is that Keynote works correctly but crashes immediately as soon as I press the play button. Any ideas?

[This post was supposed to go up several days ago.] I’m sure a few of you have already seen the latest by Action Retro: a side-by-side of OCLP running Sonoma on an A1260 (running half of its maximum RAM, and unclear if it was running a spinner or SSD), next to an M1 Max MacBook Pro with 64GB...

I am not sure if there is a better place to post this (The OCLP Github page does not allow to submit any feedback), so I will try here. Using the latest available version of OCLP 1.0.1 and updated my 2012 rMBP 15" to Sonoma which worked great. But now it ends up crashing at least once a day...

Mac Pro 5.1 SSD #1 High Sierra / Monterey SSD #2 Windows 10 OCLP 1.0.1 EFI (Macbook Air) Yes, I'm a loser I wanted to update to Sonoma and created the USB on my Macbook Air. I forgot in OCLP to select Mac Pro and created the USB for the Macvook Air. So I upgraded my Mac Pro with the efi for the...

Hello again everyone. I'm back to the place where people are nice, and actually helpful. Now I know this may not be the best place to put this thread, so please tell me if it needs to be moved, and where the best place for this query is :) I updated two of my macs yesterday to sonoma since...

I tried installing opencore legacy patcher on my imac 18,3. When I get to the step to install opencore, it is greyed out. I am assuming this is because my iMac is not supported by opencore 0.6.8...Can anyone tell me if that could be the issue? Thanks!

When trying to install Monterey to my cMP, I can boot and complete the installation from the USB stick without error. It then reboots to the macOS Installer partition, and again, seems to complete successfully. It reboots a second time, but the progress bar hangs at 25-30% for a minute or so...

hello there, i'm just wondering if i can get windows 10 or 11 on my Mac Pro 5.1... my Mac Pro 5.1: 3.06 GHz 6-Core Intel Xeon / 16GB memory / GTX 680 2GB (non-flashed) / Big Sur on NVMe SSD 512GB (using OCLP) i had windows 10 (with bootcamp drivers installed via brigadier) on SATA disk, which...

My Mac Pro had been working great for years with a Broadcom BCM94352HMB, flashed RX-580, and PCiE M2 4TB drive. Systems are Mojave, BootCamp Windows 10, Catalina, and OCLP Ventura and Sonoma. I wrecked the CPU tray connector cleaning the area and ended up buying another 5,1 in excellent shape...

For months, I've had a perfectly working system using current OCLP, Ventura and Catalina. The other day, I started up as normal in Ventura and it locked at the Apple Logo. I reset the NVRam from the OC boot picker. It still wouldn't boot Ventura. It also wouldn't even see the external USB I...

2012 Mac Pro shows no video in MacOS, but it runs fine in Windows 10 from a separate NVME (a pair of 970 EVO PLUS 512GB on a Syba.) I can see the boot screen and can watch MacOS begin to load, but the screen goes black at the login screen. Issue persists after SMC reset and COM+OPT+P+R four...
