Back up first

Have a Time Machine or full disk backup before creating USB installers or updating macOS.

Start here

Download OCLP

Find the release page, what file to choose, and why the PKG installer matters on newer versions.

 Compatibility

Is my Mac supported?

Check Intel Mac families, unsupported Apple Silicon and PowerPC, T2 notes, RAM warnings, and macOS version limits.

 Install path

Create USB and install

Follow the safer flow: create installer, build OpenCore, boot from EFI, install macOS, then apply root patches.

 Choose carefully

Sequoia, Sonoma, Ventura, Monterey

Compare version-specific OCLP notes, dropped Macs, graphics caveats, USB issues, and what is known about Tahoe.

 Updates

Update OCLP and macOS

Prepare the app, OpenCore bootloader, root patches, and macOS updates without breaking a patched install.

Practical help

Get from download to a working Mac

Most users need one of three answers: where to download the patcher, whether their Mac is supported, or how to fix something after installing or updating. The pages below follow that order.

Download without second-guessing

The download page explains where to get OpenCore Legacy Patcher, what the package is for, and what to check before opening it.

  • •Which release package to use
  • •What to avoid before opening the app
  • •How to move from download to compatibility checks

Pick the right macOS version

The macOS pages cover Sequoia, Sonoma, Ventura, and Monterey so you can understand dropped models, known limitations, and patching needs.

  • •Sequoia support notes
  • •Sonoma and Ventura caveats
  • •Monterey guidance for older Macs

Know the pieces involved

OCLP work usually involves macOS, your exact Mac model, a USB installer, OpenCore booting, GitHub releases, and post-install root patches.

  • •macOS installer and USB drive
  • •Exact Mac model identifier
  • •OpenCore booting and root patches

Recommended workflow

The safe OpenCore Legacy Patcher process

OCLP can give older Intel Macs access to newer macOS versions, but it should be treated as a system-level change. Move in this order.

1

Read requirements

Confirm the app can run on your current macOS and that the target installer can be created from your base OS.

2

Check support

Find your Mac model identifier and understand any non-Metal, Legacy Metal, USB 1.1, T1, T2, or RAM limitations.

3

Create installer

Use a USB drive, download the macOS installer, and let OCLP prepare the media where possible.

4

Install and patch

Build OpenCore, boot through EFI, install macOS, and apply post-install volume patches after the system boots.

Quick answers before you download

Yes. OpenCore Legacy Patcher is an open-source project. Use the download guide on this site so you know what to check before leaving for the release package.

No. The supported models documentation says OCLP does not support Apple Silicon or PowerPC Macs.

A USB installer is strongly recommended for major macOS upgrades. The original installer guide recommends a 32GB drive for newer Sonoma and Sequoia installers.

The current documentation used here only confirms the target range through macOS Sequoia 15.x. Do not assume Tahoe support unless OCLP release notes say it is supported.

People sometimes type openlegacy patcher, open legacy patcher, or open core legacy patcher when they mean OpenCore Legacy Patcher. The download and install guidance here is for OpenCore Legacy Patcher on supported Intel Macs.
