Hi All.
I downloaded Dosdude 1's patcher for Catalina, also a copy of Install MacOS Catalina. Successfuly created an USB Bootable Installer. But when I restarted my mac by holding down Option Key, my USB bootable Don't show up in the boot option choice. There an EFI boot among my other Boot choice but my USB Bootable is nowhere.
It's neither In the System preference Start up disK.
So I can't install Catalina.
Thank you for your help.
I'm on Macpro 3'1 runing Mojave.
