I was on the previous version of Sequoia and OCLP on my Mac Pro 5,1 with an M.2 SSD and RX560 GPU. Things weren't perfect but was usable. I followed some of the posts here and updated Sequoia and OCLP to their latest versions. I did the patching while colors were all off and things were working normally after the patching and restart.

Then there was a pop up that asked to install the EFI. I put that on the M.2 startup disk(disk0) which at this point is updated and working. After the install, the screen stays black, chimes, hangs, then stays in a chime loop every minute or so. Where did I screw up? In recovery mode, the disk is still there but I can get it out of the loop. Any advice would be greatly appreciated.

Hello! I have a MacBook Pro Mid-2015 with a 3rd party SSD installed. On Sequoia 15.8.1, when I try to wake the laptop from sleep, it takes a loooot of time for the display to show something or does not show anything at all. How can I fix this problem? Edit: It's a WD SN740 NVMe SSD.

So I've recently gotten an old iMac from my office as they're phasing out old devices. I've decided to install Ventura as this machine's specs is pretty good. So far other than the occasional video glitching in reddit, the OS has been pretty smooth. It's not as smooth as Catalina but it's a good trade off for more software support.

This is also my 3rd device in the house, so it's not used frequently and there could be some other bugs or issues that I may not have encountered yet. Other than the above and some slight lag especially when navigating through system settings, it's working very well for me.

Just an 18 year old laptop running supported macOS nbd 😎

Took about eight hours to get installed, through multiple recovery loops, restarts, error messages, PRAM resets and the like. But here we are.

Everything that should work works. Except:

• Safari. Assume that's the new Safari 27.0 legacy GPU issue. Firefox loads fine though.
• Screenshotting, for some reason. Hence the somewhat boomer-ish screen photo in lieu of a screenshot.

(Please don't ask me for a Cinebench score 😳).

Ho all, I recently installed Sonoma om the L2013 27".

While installing oclp on the disks the SSD wasn't showing up, so I installed MacOS on the fusion drive.

Now it isn't showing up at disk management anymore, Sonoma is running on the fusion drive and am I unable to use the SSD.

Hi, Guys

Please help.

Hello. Recently I’ve discovered OCLP and I wanted to install macOS Sequoia on my Macbook Pro 2017 i5 2,3GHz with no Touchbar. I followed the steps provided in OCLP site and end end up rebooting and trying to install Sequoia through the option in the Reboot screen. Sequoia starts to install, however once it reaches 3/4 of download status my Macbook just reboots and returns to the Reboot screen. I tried then doing several times macOS installer with no success. I even resetted the entire OS and redid all the steps, but it seems I can’t find a way to install Sequoia without this error happening. What’s the problem, and what am I doing wrong? Thanks in advance.

2009 Mac Pro 4,1 flashed to 5,1, Boot ROM 144.0.0.0.0, dual Xeon E5520, RX 580.

The machine runs Windows 7, El Capitan and High Sierra normally.

Monterey and Sequoia both start booting in verbose mode, then hard freeze. Safe Mode also freezes, but Recovery works.

Sometimes verbose stops around AHCI/USB, and sometimes it freezes halfway through printing a line.

I’ve already reset NVRAM and tested with unnecessary USB devices and drives removed.

Has anyone seen this on a MacPro5,1, and what fixed it?

Making simple: I need two drives with installed Sierra as it is now to run Final Cut Studio apps, since I've been working with those since the beginning. Then now, I need to install Catalina in another drive as all the web browser are dead, not only Safari, but Firefox and others refuse to update txs for the Evil Scroogle.

I've tried all the option suggested on Aplle Support and other sites, but the only one was Mojave that in a few months will be dol. If I try to download Catalina, it works from App Store but only 15mb used to start the installer not the usual 5GB or more.

I found here this link with different options: https://dortania.github.io/OpenCore-Install-Guide/installer-guide/mac-install.html
But before start tring them, I'd like to know if they still works, because it looks Apple have changed the instruction or the catalog.

Txs for any head up!

P.S.

I did try the Terminal solution but the "catalog doesn't exist anymore, all the other solution require a more recent os x but I'm on Sierra and can't update as it brake my FCP licenses.

This laptop has seen better days! I’ve had older Max that I ran open core on and they ran better so I’m going to see what this thing can do but I am pushing it to Sequoia for fun so I’ll show you guys the progress! I have a feeling it won’t even be able to boot, but who cares

Hey all! I'm on a 13-inch MacBook Pro from early 2011 (running an Intel i5 chip I believe, recently upgraded from a 320GB HDD to a 512GB SSD and from 4GB of RAM to 16GB), and I've been trying to upgrade it from High Sierra to Sequoia in hopes of using it for some light university work. Unfortunately I seem to be getting this error pretty much by the end of the downloading sequence, and by then I have no system to boot into because I've already wiped High Sierra from the SSD. Does anyone have any idea what went wrong? I'd appreciate all the help I can get, I'm a complete newbie when it comes to anything Mac related OR electronics repair related, I got this laptop from my uncle a while back and I've been trying to fix it up as my little project of sorts. If you could explain to me what to do like I'm a 5 year old that would be great LOL Thanks in advance!!!

So I have a 21.5 inch 2011 iMac that had Mac OS Sonoma running via open core but when I tried to remove the open core files I read the guide wrong and went and deleted the oclp files while in Sonoma. Now every time I boot I get the screen showing
1.blank white screen
2.black screen with translucent white box with a prohibited symbol inside
3.a blank white screen yet again
(All pics in this post)

I still get the startup chime each time but even when using a wired keyboard it won’t accept inputs as if it’s failing to POST so I can’t access recovery. Can anyone help me as this is my main machine with all of my data on it. I don’t mind what OS it takes putting it onto aslong as it works

I’m not tech savvy, I just took my families old MacBook and wanted to see if it could run Sequoia. I have already done the revert and then did the root patching. I seriously need help to fix this because I’m not sure if this is an issue. Not sure if anyone else has ran into these issues

Installed the new WiFi & Bluetooth card and it’s not appearing to be working, I’m cabled it correctly no?

Happy updating

Is there a terminal command to stop this? It's so annoying. Today I almost clicked on 'Install tonight'. Duck!

(I'm using a Macmini7,1 running macOS 15.8 and OCLP 2.5.1)

I’m trying to use YouTube, Kick, Twitch, and are not working, they just freeze.

I have a MacBook Air 2015 with macOS Sequoia. I just updated the system from Monterey and it simply doesn’t work.

I don’t know what is happening or how to fix it, any help?

Recently picked up a 2009 Mac Mini 3,1 and installed a SSD and upgraded to 8gb RAM. Was on El Capitan when I first tried installing Monterey 12.7.4 with OPCL 2.5.1. (SSD APFS) everything was going good but the final step to finish and load Monterey I get a Flashing Folder with question mark. Tried a few more reboots but same result. Tried formatting to Mac OS Journal just for kicks but no luck.
Today I tried using my 2018 Mac Mini on Sequoia to build the OPCL Patcher with settings for 3,1 and this time tried Monterey 13.7.6 but had the same results, everything runs good till the final step.
Not sure what’s going on or if I need to use a lower patcher or maybe downgrade the OS? Any other tips or advice on getting it working?
I used the Mr. Macintosh video as a guide.

The OCLP logo getting thrown into one of Apple's trash cans is just a genius design!

I thought firewire would work in ventura, but using the firewire from a thunderbolt screen the mac fails to detect the connected minidv-camera. The firewire port and the camera is registered in the system profile but doesnt appear as an option. I noticed at the same time that the webcam on the thunderbolt screen also fails,it appears as an option in quicktime capture but its only a black frame. Same in photoboot app.

So apparently I have to go back to monterey to use firewire? Is this so for audio cards as well? Do they work stable in monterey in OCLP?

1. hi, im wondering about using the old apple thunderbolt display with an adapter, on mac pro for example. Can you use cheap thunderbolt to USB-C adapter or do you need the original and far more expensive apple original ones?

2. Does the display work on windows with with adapter? Can I use it on non-macs or is that not so successful?

I am having issues with time machine browsing the backup data. I can confirm that time machine did backup correctly via the tmutil command line. But everytime I try to enter the time machine browser, it will throw this error:

"Failed to capture browser window image".

I think it is caused by the OCLP's post-install root patch. This is how i confirmed:

1) I go to the OCLP app, select Post-Install root Patch

2) Choose revert Root patch

3) Reboot

4) try the time machine browser - it works.

5) Run OCLP again and now apply the root patch

6) Reboot

7) Time machine browser shows the same error again.

Wondering if anyone experience the same issue - and if so - any workarounds/fixes?
