💡Some potential causes/fixes Coreaudiod I've seen this happen a lot on macs that are rarely ever shutdown completely coreaudiod may have some kind of memory leak but using the terminal and running the command 'sudo pkill coreaudiod' has solved the issue in these cases the coreaudio daemon will restart. Complete shutdown/restart should work too in those cases if you don't want to run anything in the terminal. Sampling Rate "The I don't know *** is causing it but this seems to work for me fix" run the Midi click on 'Macbook Pro Speakers' or whatever other audio devices you use. Changing format on the right from 44khz -> 48khz has made the popping go away for me before. As to why it worked? 🤷🏻 3rd Party Audio Daemons/Plug-Ins I have seen some issues like this come up If you have any third party audio daemons or plugins like Boom2/Boom3D, Sound Booster, BackgroundMusic. You may want to do the same thing as above with the Midi app for their virtual devices. If that isn't working, it may be worth trying to 'thoroughly' removing them. Hopefully this'll be useful for some of you. I doubt it'll cover every potential cause but I've seen these work for popping issues in several cases.
