How to Build OpenCore for Another Mac on an Apple Silicon (M2) Mac
If your older Intel Mac has had its drive completely wiped, you can use a modern Apple Silicon Mac (like an M2 MacBook Air) to create the OCLP bootable USB. However, because you are running the app on a newer machine, you must manually change the target settings in the patcher.
Why is the Button Grayed Out?
By default, OpenCore Legacy Patcher targets the machine it is currently running on. Since Apple Silicon Macs do not use OpenCore (they boot natively), OCLP disables the "Build and Install OpenCore" button to prevent configuration errors.
Step-by-Step Solution
- Change the Target Model: Open the OCLP app on your M2 Mac. On the main menu, click on Settings.
- Select the Old Mac Model: In the Settings menu, look for the dropdown menu labelled "Target Model". Change it from "MacBookAir10,1" (or host Mac) to the exact model identifier of your older Intel Mac (e.g.,
MacBookPro11,1oriMac12,1). - Save Settings: Click the "Return" or "Save" button to go back to the main menu.
- Build OpenCore: The "Build and Install OpenCore" button will now be active. Click it, wait for it to compile, and select your USB drive when prompted to install the bootloader.
Original Question: "Cannot Build or Install OpenCore on Macbook Air M2"
 | Hi everyone, I want to use my Mac Air M2 to create a bootable USB for my old Mac. For some dumb reasons that, I deleted everything on the old Mac drive, so I cannot run oclp on it. After making the bootable USB, I cannot install OpenCore to the USB because the button is grayed out, like in the picture. I plan to reinstall Catalina, but it might take a while. Does anyone know how to fix it? Thank you [link] [comments] |
