COMPAREE VERDICT
OpenCore Legacy Patcher builds an OpenCore bootloader and post-install root patches so Apple's own installers run on Macs Apple dropped, back to 2007 Penryn machines. The README lists support from Big Sur onward. Michael MJD's Mid 2009 13-inch MacBook Pro (MacBookPro5,5) had been stuck on El Capitan; with the RAM maxed at 8 GB and a fresh SSD, it ended up on Sequoia. The install itself went mostly to plan. The rough spots: he needed a USB 2.0 hub with an external keyboard and mouse, because the built-in ones use USB 1.1. The automatic root patching did not run, so he applied the patches manually over Ethernet. And installing OpenCore to the internal drive needed a small FAT32 partition workaround. Before the graphics patch the machine was nearly unusable; after it, browsing and 720p YouTube were smooth. Apple Intelligence and iPhone Mirroring cannot work, the CPU lacks AVX for some newer apps, and root patches have to be reapplied after every macOS update. If you have an old Mac gathering dust and want it useful for web and video, this is the project.
IN THE REPO
GOOD TO KNOW
- —The repository contains the OpenCore Legacy Patcher app source, documentation and patch sets; prebuilt apps are on the Releases page.
- —No hardware BOM. You need a supported Mac (Penryn/2007 and newer) and at least 3 GB RAM for Sonoma or newer; the patcher app itself needs OS X Yosemite 10.10 or later.
- —macOS comes from Apple's own installers, downloaded by the app; OCLP builds the bootloader and applies patches. Nothing is pirated.
- —The licence is a custom BSD-style licence (LICENSE.txt) with an advertising/acknowledgement clause; it is not a standard SPDX licence.
- —Apple Intelligence (needs a Neural Engine) and iPhone Mirroring (needs a T2) do not work on OCLP-patched Macs.

Installing macOS Sequoia on a 15 Year Old MacBook!21:47
Michael MJD's walkthrough (21 Nov 2024, OCLP 2.1.2 at the time) of installing macOS Sequoia on a Mid 2009 13-inch MacBook Pro, including the USB hub workaround, manual root patching and the About This Mac screen.

Start here
Navigation into the creator’s own docs — we don’t rewrite the guide, we route you to the source.
- 1.Read the OpenCore Legacy Patcher guide and confirm your model on the Supported Models page. (The Mid 2009 13-inch MacBook Pro is MacBookPro5,5. Check the RAM requirement (3 GB+ for Sonoma and newer).)
- 2.Download the OpenCore-Patcher app from the GitHub Releases page. (The app needs OS X Yosemite or later. Michael ran it on his modern MacBook Pro because the old one had a blank SSD.)
- 3.Use the app to download macOS and write the installer to a 32 GB USB drive. (The whole drive is erased. If you are building for another Mac, set the target model in Settings first so automatic root patching works later.)
- 4.Set the target model in Settings, then Build and Install OpenCore to the USB drive.(Michael picked MacBookPro5,5 and turned on verbose boot. On the old Mac, hold Option, choose EFI Boot, then the macOS installer.)
- 5.After install, apply the Post-Install Root Patches and install OpenCore to the internal drive. (Use Ethernet so all patches install at once. Without them, graphics, Wi-Fi and the built-in keyboard/trackpad on this model do not work.)

KNOWN ISSUES
- Not enough RAM: Sonoma and newer need 3 GB or more, and 2 GB Macs cannot install Sonoma or Sequoia. Michael maxed his MacBook Pro at 8 GB and added an SSD.
- On 2008/2009 laptops the built-in keyboard and trackpad use USB 1.1, which Ventura and later removed. Plug an external keyboard and mouse into a USB 2.0 hub during install, then root-patch to get the built-in ones back.
- Root patches (graphics, Wi-Fi, USB 1.1) are installed after macOS. OCLP should prompt automatically if it built the USB with the right target model, but in the video it did not, so Michael ran it by hand. Use Ethernet, otherwise OCLP may install only the Wi-Fi patch first.
- Use a 32 GB USB drive. The docs say later Sonoma and Sequoia installers plus patches do not fit on 16 GB.
- Root patches are wiped by every macOS update and must be reinstalled; OCLP prompts you when they are missing.
- Pre-Sandy Bridge CPUs lack AVX/AVX2, and some newer apps refuse to run on them even on a patched system.
- You cannot patch over an install made with other patchers (Patched Sur, bigmac); only clean installs and upgrades are supported, though you can reinstall with OCLP and keep your data.
Does this work on every old Mac?
No. It supports Penryn (2007) and newer Macs; check the Supported Models page for yours. RAM matters too: Sonoma and newer need 3 GB or more, and Macs with 2 GB cannot install Sonoma or Sequoia.
Is this pirating macOS?
No. The patcher downloads Apple's own macOS installers and patches them to run on unsupported Macs. Michael downloaded Sequoia straight from inside the app.
Will my old Mac be fast?
No. Michael's 2009 MacBook Pro (Core 2 Duo 2.26 GHz, GeForce 9400M, 8 GB RAM, SSD) was barely usable until the graphics root patches went in. After that it handled web browsing and 720p YouTube smoothly. The CPU also lacks AVX, so some newer apps will not run at all.
What does NOT work on unsupported Macs?
Apple Intelligence needs a Neural Engine (Apple Silicon only), and iPhone Mirroring needs a T2 chip, so neither works. On 2008/2009 laptops the built-in keyboard and trackpad use USB 1.1, which macOS 13+ dropped. They only work after root patching, so you need a USB 2.0 hub with an external keyboard and mouse for the install.
Can I undo this and go back to the original macOS?
Yes. OCLP does no firmware patching, and its changes are done in memory at boot. The uninstall guide reverts by wiping the disk and installing a natively supported macOS from a USB installer or Internet Recovery, then resetting NVRAM. Note: after you remove OpenCore, the Mac will not boot the patched macOS, so have a bootable USB ready.

OpenCore Legacy Patcher is a Python-based Dortania project built on Acidanthera's OpenCorePkg and Lilu. Its main co-authors are Dhinak G and Mykola Grymalyuk (Khronokernel), joined by many contributors. Its stated goal is to breathe new life into Macs Apple no longer supports. The video on this page is by YouTuber Michael MJD, who installed Sequoia on his Mid 2009 13-inch MacBook Pro in November 2024.

The community Discord (OpenCore Patcher Paradise) is maintained by users, not Dortania. The biggest things to know before starting: Sonoma and newer need 3 GB+ RAM. On 2008/2009 laptops you need a USB 2.0 hub with an external keyboard and mouse until the USB 1.1 root patch is in. And root patches have to be reapplied after every macOS update.
