You see what the video does it freezes afterwards in a Kernal Panics when I reboot into Monterey (after it glitches out). I have a 2008 iMac 20 inch with an ATI Radeon HD 2600 XT.

Just updated to the latest macOS via OCLP. Works like a charm. No issues to state so far. Runs great on this 2012 quad-core machine. 13 years old and still trekking strong. Thanks OCLP community.

Hi everyone,
I'm running macOS Sequoia 15.3.2 on an iMac 27" (2017) using OCLP. The system runs well overall, but I'm having a persistent issue with GPU VRAM usage.

My Radeon Pro 580 8GB stays at 95–100% VRAM usage most of the time. This happens even when I'm not doing anything GPU-intensive. I usually have Arc and Slack open, along with some other regular apps, and nothing too heavy is running. Still, VRAM stays maxed out, and I often experience lag and stuttering, especially during video calls while screen sharing.

Closing apps helps reduce usage slightly, but it never drops below 50%, which seems abnormal. On my MacBook Pro 2019 (Radeon Pro 5500M 8GB), running the same setup and apps, VRAM usage stays around 20% or less.

Apps like Arc, Chrome, and other Electron-based apps seem to be the biggest contributors to the high VRAM usage.

Has anyone experienced something similar with Sequoia and OCLP on AMD GPUs? Any tips or insight would be greatly appreciated. 🙏

A double thumbs up for this release. My MacBook graphics returned to normal speed after this update. Performance overall is great and prevented me from throwing the MacBook against a wall!

A job well done - Thanks to all

Hi. I installed Ventura on a late 2012 21' iMac. Everything seems to be fine, maybe just a few slight slowdowns every now and then.

However, I saw that in my shared folder (where I have some documents shared with a second account) these 4 opencore files (attached photo). I don't know what they are: can you tell me more and if I can delete them? Thanks!

Got it for free! It did not boot, only with the Questionmark folder. And now the main question is, which MacOS should i install? And which runs best on a machine like this?

Full warning translated: “Images cannot be initialised. This usually happens when running in an unsupported virtual machine environment or when running on an unsupported Mac.”

I have gotten Garageband from another Reddit post with all comments saying that it worked perfectly fine so I wanted to try it out on my iMac mid 2011 with Monterey. (They also used OCLP)

Before the warning comes up, I’m able to play a note, so it should work.

What is going on and how can I fix this?

Hey all,

I’m running macOS Sequoia 15.3.2 on an iMac 27" (2017) using OCLP. Everything works fine, but I’ve noticed something odd with GPU memory usage.

My Radeon Pro 580 8GB often sits at 95–100% VRAM usage, even when I’m only running apps like Arc, Slack, Chrome, and VSCode. I tried closing them one by one, and while usage drops slightly, it never really goes below 4 GB, even when idle.

It sometimes causes stuttering and lag, especially during video calls and screen sharing, which doesn’t happen on my MacBook Pro 2019 (i9 + Radeon Pro 5500M 8GB) running the same Sequoia version with the same apps and VRAM there rarely exceeds 20%.

Is this expected behavior on Sequoia with AMD GPUs (especially via OCLP), or is something off?

Appreciate any thoughts, suggestions, or shared experiences 🙏

I need some help. I downloaded open core legacy for a 2017 MacBook Pro. I got the point of installing it where it is supposed to boot on its own 4 times. I keep getting stuck on this screen and have to go through the process all over again. What am I doing wrong? Just keeps going to this screen. When I click install macOS sequoia it acts like it’s going to work and just ends up back at this screen again. I chose to delete my existing hard drive so I can’t even go back to my old Operating system.

So i have just installed oclp big sur on imac 8,1 and i applied rootpatches but it still says the same ones are available, is there a fix for this? Are the root patches installed but saying their not ??

I cant find anything besides this ive resarted and held alt like 6 times so far and this keeps showing up ive already installed it and i neeed to boot the efi to continue it and it wont show up any more

I have a 2012 Mac, currently running on Catalina 10.15.7.

I had a lot of trouble setting it up previously, as it came from a school and took me about 2 days to get working (I can't really remember what I did as this was about 4 years ago). The only local disk I can see OpenCore finding is this External drive which I'm concerned about - is there any way to find out if this will cause any issues or does it look like it's okay to proceed with?

If it's best to hold off, what's the best next step?

I'm new to a lot of this, so any ELI5's would be greatly appreciated

Note: update is still running so I’ll let you know how it goes

Howdy folks,

I have been running Sonoma on OCLP on my Mac Mini 2012 for months now just fine. I installed the latest updates to try to get additional security, I think that was 14.7.5 IRCC it was something like 12 GB so it may have been a while.

I keep hanging at the same 1/3 progress bar load point with the same user account as before that had functioned.

I have tried

1 - Holding shift as it boots to try to enter safe mode (doesnt seem to do anything.)

2 - Holding "option" as it boots selecting EFI boot, then holding space bar, holding CTRL to get a circle on "restore"

3 Running First aid on disk, both the macOS install and the main SSD.

4 Restart (hangs at same point)

5 Reset NRAM/PRAM from menu entery as above - hangs at same point

6 Reinstall Sonoma - hangs at same point.

REALLY hoping theres a way to fix without a full delete reinstall from a flash drive. Any tips?

Hi I’m trying to install sequoia on this MacBook Pro 2012 but it always gets stuck at this point. Anyone else has this issue and how did you manage? I tried several times repeating the procedure but it always ends up here

Hello there!

I've been using Hackintosh on my PC for a while now, but on Windows, a game didn't work properly because my BIOS version was outdated. I've decided to update the BIOS, and that fixed my issue.

BUT I use Hackintosh for work, and today I wanted to boot it up, but it looks like it got wrecked. I thought maybe by updating my BIOS settings were set back to default, so I checked them, but they weren't. I set it back to defaults manually and changed the settings which are need to be changed, but that didn't fix my issue either. What could be the case? Should I roll back the BIOS version because, of course, I'm prioritizing my work over a game?
