No Windows download of the OCLP app
If you want the patcher itself, download OpenCore-Patcher.pkg on macOS. If you want Windows on an older Mac, build OpenCore from macOS first, then prepare a UEFI Windows installer.
- Download the macOS OpenCore Legacy Patcher package from the download page.
- Follow the UEFI Windows boot steps below on supported older Mac families.
- This does not turn a Windows PC into a Mac.
Windows 10 and Windows 11 through OpenCore
Start on macOS. Download OpenCore-Patcher.pkg, build OpenCore for the target Mac, then prepare a UEFI Windows installer.
Only UEFI Windows installations appear in the OCLP boot picker. Legacy MBR Windows installs are outside this workflow.
- Download the macOS OCLP package first. There is no separate Windows app build.
- Keep a dedicated FAT OpenCore partition so Windows setup does not overwrite the bootloader.
- Confirm your Mac family against the Windows UEFI recommendations below before you wipe disks.
Windows UEFI minimum recommendations
The Windows guide focuses on modern Windows 10 and 11 installations without Boot Camp Assistant and recommends UEFI Windows only on certain older Mac families.
- 2015 MacBook or newer
- 2011 MacBook Air or newer
- 2011 MacBook Pro or newer
- 2011 Mac mini or newer
- 2009 Mac Pro or newer, upgraded GPU preferred
- 2010 iMac or newer, upgraded GPU preferred
- 2009 Xserve, upgraded GPU preferred
Important bootloader warning
Create a separate 200MB FAT partition for OpenCore when booting Windows. This can prevent Windows from overwriting OpenCore with its own bootloader in the EFI partition.
The Windows bootloader can brick these systems if it loads through the stock boot picker. Follow the dedicated removal workaround before rebooting.
