        Hi there,

         

        I had problems with high CPU load of kernel_task for weeks now and decided to clean up my kexts. I deleted the Silabs Usb Driver kext and invalidated the cache via

        sudo kextcache -invalidate /

         

        This gave the following strange output

         

        Untrusted kexts are not allowed
        Kext rejected due to invalid signature: <OSKext 0x7ffc9675a160 [0x7fff89e2c8c0]> { URL = "file:///Library/Apple/System/Library/Extensions/AppleUSBEthernetHost.kext/", ID = "com.apple.macos.driver.AppleUSBEthernetHost" }
        

         

        How can this be? Is this kext from Apple corrupt or something?

         

        I'm on macOS 10.15.4.

         

        Best regards
