I'm trying to load a kext following this official documentation page, but when i try to load the kext with: sudo kextutil -t /tmp/resourceCompressor.kext/ I get this error: Executing: /usr/bin/kmutil load --bundle-path /tmp/resourceCompressor.kext Error Domain=KMErrorDomain Code=71 "Kernel request failed: (libkern/kext) not loadable (reason unspecified) (-603946989)" UserInfo={NSLocalizedDescription=Kernel request failed: (libkern/kext) not loadable (reason unspecified) (-603946989)} Also if i try to use the no load option i get another error: sudo kextutil -t -n /tmp/resourceCompressor.kext/ kextutil: -n is not a supported kmutil mode As far as i understand the kextutil, kextload, kextunload binaries have been deprecated i favour of kmutil but i cant find any guide on how to use it, and still i dont know why my kext cant be load. What can I do to load it?

Can someone actually explain me what dyld_shared_cache_x86_64 and other files located at /System/Library/dyld are? I know that dyld is the dynamic libraries loader which recursively load required dylib into memory for every launched process but i still dont get what dyld_cache and aot_cache exactly are? I'm looking to a detailed explanation about those.

Can dyld, dylib and shared cache be compress and decompress when required to solve storage problem?
