lolo19430 Posted June 23, 2020 Author Share Posted June 23, 2020 It works now. I used an external drive to launch Catalina. Now he tells me that the disc has the wrong format. That you have to erase and partition with the disk manager. But I can't find it. Can you help me ? Link to comment Share on other sites More sharing options...
