DISCLAIMER: Please understand that installing macOS Sequoia on your unsupported Mac with OCLP is not supported by Apple, and you are doing so at your own risk. But, a ton of work went into getting the patcher to work by the OCLP Developers. Some things might not work exactly right, but the patcher is a work in progress. ALWAYS BACKUP YOUR FILES FIRST BEFORE YOU UPGRADE!")
