Apple’s Content Caching is not available when running OSX in a VM.
It seems Apple is detecting if it’s running inside a VM:
$ sudo /usr/bin/AssetCacheManagerUtil activate AssetCacheManagerUtil Failed to activate content caching: Error Domain=ACSMErrorDomain Code=5 "virtual machine"...
To get around this, you can patch the kernel to remove the cpuid features check:
- First disable SIP
sudo mount -uw /
sudo kextcache -i /
