Mac mini late 2022 6,2 running EI Capitan. Trying to create a boot disk (usb) for a clean install of Sonoma. Getting the above error when creating the install disk using a usb. Open core legacy patcher version 1.0.1. On open core legacy patcher, first i downloaded sonoma. After download and verification is complete, when creating installer, i have this error. Any help is really appreciated. Thanks.
