Dummy check please. Is it true that:
- Jack can serve as audio loopback software between MacOS audio apps such as Pd
- Jack can run on an M2 processor
- The Qjackctl.app that is bundled with the Jack MacOS download runs on Monterrey without any additional runtime frameworks installed
- For Pd to send/receive from a Jack channel, Jack has to be running and you have to select Jack in the audio settings before you can select which particular Jack channel you want for input or output
- Soundflower is obsolete; Jack is current
Edit: I can confirm the 2nd through 4th bullet point but not the first and last. I've seen 2 tutorial videos on Mac audio loopback where you can see that the presenter has Soundflower installed in addition to whatever loopback software they were demonstrating, so that makes me scratch my head. RE that first point, I'm tentatively concluding that an audio app has to be Jack-aware (like Pd) in order for it to be routed by Jack, which isn't a requirement of other loopback drivers like Soundflower or Blackhole. Finally, it's worth noting that Jack doesn't come with an uninstaller, so to get rid of it you have to manually remove files from /usr/local and below, and the list of files can be found on one of the windows of the installation package if you scroll down. If that's not your cup of tea, don't install it!
TLDR: I'm not sure why anyone would want to use Jack on a Mac. Still happy to be schooled though.
