On version 10.15 Beta (19A558d) I can't seem to get aptX HD to work anymore and was wondering if anyone else has aptX HD working still? Could this possibly have been removed?

Hardware: Late 2018 MacBook Pro 15, Bowers & Wilkins PX.

Trying to force aptX via Bluetooth Explorer from Additional Tools for XCode 11 GM Seed doesn't seem to be giving any results either. I have tried the following combinations, restarting Bluetooth each time:

☐ Force use of aptX ☐ Disable AAC
☐ Disable aptX ☑️ Enable AAC
Result: Active Codec: AAC

☑️ Force use of aptX ☑️ Disable AAC
☐ Disable aptX ☐ Enable AAC
Result: Active Codec: SBC

☑️ Force use of aptX ☐ Disable AAC
☐ Disable aptX ☑️ Enable AAC
Result: Active Codec: AAC

I had the exact same issue with a 13 inch model. Searching elsewhere, some people on r/headphones discussed what is better between AAC and aptX and seems to have agreed AAC is better. In that sense, I think I'm satisfied to listen to my PXs on AAC.

I didn't realize Catalina had this issue until I switched my PXs from my iPad to my Mac and heard a huge difference in the balance between frequencies (equalizers off on both devices), so checked in my Bluetooth menu and found it was also to AAC, like your situation. For what it's worth, I also ran sudo defaults write bluetoothaudiod "Enable AptX codec" -bool true and with "Enable AAC codec -bool false (and restarted my Bluetooth module). They had no impact – but I think does the same as your approach.

However, when I'm using my PXs, it's to focus on work, not music. If sound quality really bothers you and you prefer aptX, I hope there's another solution! Maybe this is just a beta build bug!

  • Looks like that discussion was about aptX, whereas the PX support aptX HD (which I've corrected in the OP now). I believe aptX HD is noticeable. I can't seem to find any info about this though and even the final release still has this issue :-( – SRG3006 Oct 8 at 17:26

For those still looking, it appears that aptX support has been silently removed from macOS Catalina (10.15); even in the public release.

    Hi Ben, it would be best to support answers like this with a reference that can be followed through. This will ensure that if the answer changes, new readers can find the reference link and be sure to obtain any updates (if any). – Danijel-James W Oct 9 at 1:16
  • Yes, if you've got a source that would be excellent. I can't seem to find anything from Apple. I've searched release logs of the betas and all. – SRG3006 Oct 10 at 15:19
  • Related discussion: discussions.apple.com/thread/250719060, but no facts support was actually removed so far. – extempl 20 hours ago
