OpenCore Legacy Patcher – Installation

Installing OpenCore Legacy Patcher (OCLP) allows you to run newer versions of macOS on unsupported Macs. This guide provides a detailed, step-by-step process to ensure a smooth installation.

Prerequisites

1. Supported Mac: Verify that your Mac model is supported by OCLP. Check the official list on the OpenCore Legacy Patcher site.
2. USB Drive: A USB flash drive with at least 16 GB of storage.
3. macOS Installer: Access to a compatible macOS installer (Big Sur, Monterey, or Ventura).
4. Internet Connection: Required for downloading files.

Step 1: Format the USB Drive

1. Insert the USB drive into your Mac.
2. Open Disk Utility (found in Applications > Utilities).
3. Select your USB drive from the list on the left.
4. Click on Erase at the top.
5. Set the following options:
   • Name: Choose a name (e.g., “OCLP”).
   • Format: Select MS-DOS (FAT).
   • Scheme: Choose GUID Partition Map.
6. Click Erase to format the drive. This will delete all data on it.

Step 2: Download OpenCore Legacy Patcher

1. Download the latest version of OCLP (e.g., OpenCore-Legacy-Patcher-0.x.x.app).
2. Extract the downloaded file if it’s in a compressed format.

Step 3: Launch OpenCore Legacy Patcher

1. Open the OCLP application you just downloaded.
2. You may need to allow it through your Mac’s security settings if prompted.

Step 4: Create macOS Installer

1. In OCLP, click on Create macOS Installer.
2. Select Download macOS Installer if you don’t have one already, or choose Use Existing macOS Installer if you have downloaded it previously.
3. Follow the prompts to select your desired macOS version and wait for it to download (this can take some time).

Step 5: Install to USB Drive

1. After downloading, select your formatted USB drive in OCLP.
2. Click on Install to USB Drive.
3. Enter your admin password when prompted.
4. The installation process will take some time as OCLP creates a bootable EFI partition and copies necessary files to the USB drive.

Step 6: Install OpenCore to Disk

1. Once installation completes, OCLP will prompt you to install OpenCore to disk.
2. Select this option and choose your USB drive again for installation.
3. Confirm and wait for the process to finish, which may include verifying files.

Step 7: Reboot and Access OpenCore

1. After installation, reboot your Mac.
2. Immediately hold down the Option (⌥) key while your Mac is starting up.
3. In the boot picker menu, select the OpenCore EFI option (it will have an OpenCore logo).

Step 8: Install macOS

1. After selecting OpenCore, you will be taken to another boot picker where you can choose your macOS installer from the USB drive.
2. Proceed with the installation as you would normally do with any macOS setup.
3. Be aware that modern installations may require several reboots; if it restarts and returns to the beginning of the installation process, simply reboot and select the incomplete install option from OpenCore’s boot picker.

Step 9: Post-Installation Checks

1. Once macOS is installed, launch OCLP again from your Applications folder.
2. Run any necessary post-install patches as instructed by OCLP to ensure full functionality of your hardware.
