I know there's been a lot of talk in this thread about APT-X, AAC and SBC, so hopefully this is a relevant post. A friend of mine sent me this article today and I just finished building my first Hackintosh running Mojave. I've been playing around with the settings and i'm happy to report that AAC does indeed sound much better than the default SBC codec. I haven't tried it with AptX as I don't think I own any TWS' that support it. Anyways, Hope this help someone, I really enjoy using the graph and getting to see my bit rates etc. I've also noticed that increasing the quality of AAC and SBC causes some cutouts on on my anbes 359's the signal all but failed. It's important to note when changing settings, you have to save and then turn bluetooth off on the mac, then back on . I'd be interested to hear from those who are using Real MacBooks as to what their experience is when adjusting the bit rates. Here's the Link and some screenshots.
