I feel confident in what I say but mistakes can always slip into one's memoryĪgain if a kernel extension adds functionality you want/need and you trust the developer and feel certain enough about the quality of the product I wouldn't worry too much. I will add though that I'm writing this by memory so if there are slight flaws in how I've remembered this feel free to correct me.

If you want system audio, youll have to use a program like Loopback (paid) or Blackhole (free) or a hardware solution like a mixer that can send system audio back into the mic input since Mac OS doesnt trust you enough to just have it built in without a system extension. That and of course the fact that kernel extensions will inherently open more attack vectors to kernel privilege levels Ive been using OBS on an M1 Mac Mini for streaming my music production with some wrestling. I personally trust the developers, and the app has been around for a long time, so I have no problem doing this.

Audio Hijack may request to install the InstantOn, which saves having to close and reopen applications to hijack their audio.

Since a kernel extension lives in the memory space of the kernel, it would change the hash value so this function needs to be turned off. Click 'Hijack' at the top left, and now your audio is filtered. If it doesn't match it's considered no longer trusted. In the highest security mode, the whole kernel is checked against a hash of what Apple knows at build-time. The great debate over whether Apples benchmarks comparing an M1 Ultra Mac Studio to a similar Intel-based computer. The reason you need to enter reduced security to have kernel extensions now is new hardware features with T2 and newer Macs (T1 maybe? I can't remember when it was introduced). The FUSE project sort of tries to do the same for file system support, though FUSE on the Mac right now is itself a kernel extension, but then it allows user-space programs to exist that act as file system extensions going through the FUSE kernel extension without each file system extension itself needing to be in the kernel. Sort of making these extensions more like exokernel designs in a way. However there are still some things you can't do without a kernel extension so that is still supported, though Apple will likely keep expanding the DriverKit model to encompass more use-cases. Kernel extensions that have a users-ace replacement in place are considered deprecated. Which means the programs won't need full system access, and they will effectively be as harmless as any other program, while still being able to for example make drivers to interact with USB devices. That is, they have released a users-ace frameworks called DriverKit, so that a lot of things that previously required kernel extensions can now be done from Userspace. From this point on my message is just extra unnecessary background info.Īpple is sort of phasing out kernel extensions.
