tried..As soon after clover boots stop sign comes up. I guess something is wrong with Clover??
Settings overwritten? No Idea. In Clover i clicked on USB Ownership and USB Injection and the keyboard was working. Before from 10 restarts 2 times usb worked. Something wrong with the usb connection on mobo? I disconnected anything besides Monitor and Keyboard. Even all HDD disconnected only OSX SSD is connected.
Your kernel cache is borked. It looks as though you installed or removed a kext from the /Library/Extensions or /System/Library/Extensions folder without rebuilding the cache and repairing permissions.
You need to boot your system without any caches. This option has been removed from Clover all recnet versions of Clover. So you will need to create a USB drive with just Clover installed, an old version. But still using your current CLOVER folder.
You will need to use the USB Clover drive to boot your system, when on the boot screen and with your macOS drive highlighted, press the spacebar. The option to boot without caches should be in the list of boot options.
To create a USB with Clove i use the instructions i have from you??? All what i did was a repair with Kext Utility. Didn't install anything besides updates for Apps like Cubase, Studio One and Plugins. I always use Kext Utility after installing Apps or update Apps
Having now trouble to get USB Connection to work. Only Keyboard is working. When i put the USB Drive in the in Boot it stops at Loading Operation System. Do i need to make a Boot Drive with Sierra and then install Clover on it???
If you are running Sierra or High Sierra then yes. Kext Utility will work just fine.
If you are running Catalina then no, Kext Utility will not work due to the additional security processes implimented by Apple. You would need to use Hackintool, which mounts and changes the Catalina-Data partition so it is in Read and Write mode.
Under normal circumstances the Catalina-Data partition is in Read-only mode.
