djuby 0 Posted July 30, 2020 Hi, I downloaded Niresh Catalina installation image and restored it to a USB Drive. When I try booting from it, it won't boot from it. Tried it on several configurations. What may be the problem. Any suggestions will be greatly appreciated. Best regards. Share this post Link to post Share on other sites
