    MP 1,1-5,1 OCLP Bootpicker does not show OpenCore USB boot drive

    Hello, I'm running Open Core Lagacy Patcher on my old Mac Pro 4.1 with Sonoma. I have created a USB bootable install drive with OpenCore as a backup, but when I start the Mac the usb drive is not displayed in OpenCores boot picker, even if I press the spacebar. Does anyone know how to fix this...
