Select your type of Mac in the dropdown menu.

The patch tool automatically detects your Mac model and shows what you have here. If you are unsure at all which Mac you have, select the model listed here.

My suggestion is that you select ALL of the checkboxes that you can. It does not hurt to do so and it can be helpful later on. Most of the checkboxes are necessary for Mojave to run properly anyways.

Choose the drive for the patches (the one where you just installed Mojave). Click patch after doing all of the necessary things above.
