I am now using a USB SanDisk 3.2Gen1 Media with 32GB. I made the bootable Monterey USB using the local guide once more. But I am working on Mojave so the app Disc Utility does not give me the option to "Click Current and choose 1 Partition" instead there is already 1 partition when I format the drive as GUID / MacOS Ext. Journ. This can't be the problem, can it? OK so silly me thought I'd give Clover5157 another try for my next Monterey attempt, as I am using Clover4934 on my Mojave build and it works excellently. I thought maybe I can refer to the config.plist of my Mojave Clover build and see where it gets me with the config.plist on my Monterey USB's Clover EFI. But, formatting the EFI as FAT32 does not work as I get a permission denial (see screenshot). Any point in continuing? I expect you will again advise me to go for OpenCore... but I just loved the easyness of Clover and it worked great for me since 2011 El Capitan so... By the way, ever since I started working on the Monterey update my Mojave also changed its bootup process, it is now seemingly in verbose mode as it lists all the code steps. (Could this be caused by the -v boot flag set in the OpenCore config.plist of the Monterey USB? I so do not get it...) And ever so often, my Mojave build now panics on bootup, always at the same spot. Could this be a general problem ? I also attached the screenshot of the panic. Thanks.
