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
