Administrators Hervé Posted July 7, 2020 Administrators Share Posted July 7, 2020 The Catalina guide does say that the kexts included in the posted pack may be out of date and will require to be replaced by latest versions. Make sure you do that. 1 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted July 8, 2020 Moderators Share Posted July 8, 2020 You need to be more specific. Why did you install Mojave? I thought you want Catalina. What error are you encountering? Did you set the BIOS according to the guide? Do you have an NVMe drive? If yes, what brand and model? 1 Link to comment Share on other sites More sharing options...
