macOS Kernel Extensions are officially deprecated
Interesting.<p>The company I worked for and our competitor VMWare both had to create small kexts to enable on-the-fly capture of USB devices. We both accessed USB devices from user-space, but we needed to put small kexts in the kernel to prevent class drivers from being automatically attached to general USB devices. There was really no race-free user-space way of doing this and Apple ignored our messages on their dev forums when we asked for assistance.<p>I wonder if they’ve added an interface for this? Or maybe promiscuous USB device control  just isn’t going to be possible now?
