!!MY COMPUTER UPDATE!!

Upgraded from 15.7.7 to 15.7.9 successfully on my iMac 18.3 Retina 5k 2017 with SSD and Radeon GPU. Also confirm wifi, ethernet and Airplay Receiver enable with "iMac19,1" SMBIOS Spoof Model. ALL WORKS GREAT!! 😄

Hi all

I have recently used OCLP to install Monterey on a MacBook Pro 9,2. Install went fine, system is running a bit laggy which I can live with however when attempting to install office365 (version 16.88) I am getting an install failure at the last step (error code 112).
This worked fine on a similar install on late 2012 IMac.

Has anyone ran into similar issue or could offer advice?

Just updated to Sequoia 15.8 and after root patching my 2013 Mac Pro fails to boot.
If I reinstall Sequoia it boots fine without root patches, I’ve disabled file vault and log in items and it’s still failing.

Anyone else having issues?

I would like to express my sincere appreciation to the OCLP developers and all contributors to the project.

I own a 27-inch Retina 5K Late 2014 iMac, and without OpenCore Legacy Patcher, I would likely have retired this machine years ago. At one point, I expected it to become outdated, slow, or unsupported by modern versions of macOS. However, this has not occurred.

Instead, the system remains fully functional and continues to serve as an integral part of my daily workflow.

Notably, I am now running macOS Sequoia via OCLP v2.4.1, and the performance has surpassed my expectations for a machine of this age. Hardware released in 2014 remains practical and usable in 2026. I have upgraded the RAM to 32 GB 1600 MHz DDR3 and plan to install a SATA hard drive or fusion drive with a 1 TB SSD.

The iMac continues to perform reliably across a range of tasks, including web browsing, productivity applications, media consumption, and moderately demanding workloads. Although Apple has officially ended support for this model, OCLP has extended its usable lifespan in a meaningful, practical way.

I value not only the ability to install newer versions of macOS, but also the broader philosophy underlying the project. OCLP challenges the assumption that hardware becomes obsolete solely due to software support limitations. It provides an alternative to the typical replacement cycle, encouraging continued use of devices that remain fully capable.

It is also notable that I have been able to run light gaming on this system. Although it is not designed for gaming, it performs better than expected for its age and can still run older, less demanding titles satisfactorily.

Naturally, there are limitations and occasional quirks when running modern software on unsupported hardware. However, these issues are minor compared to the overall stability and usability that OCLP enables.

I extend my sincere thanks to everyone involved in developing, maintaining, testing, and documenting OCLP. The effort and expertise required to sustain a project of this nature are considerable, and the impact is substantial. OCLP has extended the practical lifespan of my iMac by years and has helped prevent a fully functional device from becoming unnecessary electronic waste.

Beyond the technical achievement, OCLP represents a more sustainable, user-focused approach to computing that prioritizes longevity and user choice.

My late 2014 27-inch iMac continues to perform reliably and remains an essential part of my setup.

2014 → 2026 and beyond.

Thank you, OCLP 🖥️🍎

Just wanted to confirm. I have a 2016 mbp on Ventura. If I want to use OCLP to go to Sequoia, I can still do an upgrade install (not clean) for Sequoia and keep my bootcamp partition functional as well, correct?

I thank the oclp team very much for making it possible to bring old macs to new macos. I used it on imacs, mac minis and macbooks and almost always everything went perfectly. Now I have a macbook neo which is not the fastest macbook but it is enough for me. Thanks again to the oclp team and also to the community.

I’ve installed Sonoma using OCLP, but it now wont let me use safari or download apps from the App Store. What is going? i just want to use ChatGPT desktop app on my 2015 MacBook 😭

UPDATE: apparently updating safari to the most recent version for Sonoma was the trick!

As per the TL;DR title, I let someone else use the machine only for them to update it after telling not to mess around in the settings. Anyway, booting into the standard home drive takes me to the log in screen though the on device keyboard and track pad are non-functional, wallpaper loads as expected. Went to the docs to find this page, though I don't have a USB A hub to test this out and the docs reference even older macbook pros to be affected, not the 2012 model in question

Worth noting the following:

- attempting a safemode boot by holding shift on the only visible disk in the boot menu loads for a minute ten spits me back out at the boot selector instead of a the log in page,

- booting into recovery works absolutely fine,

- using a power only USB A to USB C adapter I did manage to find out that although external keyboards won't work, enough power is still being delivered to charge a phone, and

- I've lost the original installer drive and only have an 8GB drive and a machine running Linux at the ready. I could try creating installer media using a third party tool but i'm not sure they'd be good copies, as per this github page.

This might then be a missing driver issue as per the docs, and I'm wondering if there is a way to find the drivers I need on a separate machine, download them onto a flash drive and install them using the recovery mode terminal or some other software. Problem here is I believe the drive is encrypted with FileVault2, though I'm not sure how to test that and how installing those drivers would work. I could always fall back to a clean OSX install, but I'd rather keep the data on the disk... I have no backups. If there is a way to unlock the drive (I know the password still, its just I can't interface with the UI,) please do let me know!

I have an iMac14,2 with 3 TB Fusion Drive.

On my Fusion drive I now have 1 APFS container with 2 volumes: 1 with the old OS (Catalina?) and 1 with OCLP/Sequoia. Normally I just boot OCLP/Sequoia. I kept the old OS just in case ...

Sequoia is working well but startup process is very slow and also opening large folders is slow.

I wonder if the SSD part of my Fusion drive might be permanently occupied by the old OS.

Would you just delete the volume with the old container? Will I have to re-install OCLP/Sequoia after that to bring it's major parts to SSD?

Or is that slow issue something completely different?

About 3-4 years ago, I used an early version of OCLP to upgrade my 2017 MBA to Ventura. I didn't want to go any higher with only 8gb RAM and only a 125gb SSD. At this time, I cannot find the OCLP app in the Applications folder. Where else can I look?
