Enable Aptx codec on Mac

I was testing your theory today. Indeed, aptX remained 100%. Very similar to

Bug with the name. I hope they correct in the future. Checked in Bluetooth Explorer.Ran using the check box in the SBC codec menu and aptX to check bitrate in one case or another. It turned out when put in priority aptX the bitrate was exclusively 384 kb/s and it was not possible to change it by any software, which is possible only with this code. Then banned aptX and it turned out bitrate which is possible only in SBC 327 kb/s.Plus it was possible to change bitpool, which immediately led to the fall of bitrate and sound quality.

And they do it on a sneaky way... the best and most used codec is dropped... I stoped buying iphones and i got so much more with android and i think this will be my last apple product (a $3000 macbook pro btw), i think windows 10 got to the point macos has little to offer right know (only dropping compatibility with older apps and most used codecs...) Well done new Apple. I am out. I am formatting osx like i did on the older macbook and installing windows, i wont be using SBC codec thats for sure.

Same thing here. I paid $300 for a pair of Sennheiser Momentum II with APTX headphones knowing I could use Apple's own Bluetooth Explorer to enable the APTX codec. It worked great for a month, and now Apple has silently removed support in Catalina. I've decided to sell my headphones on eBay.

Screw you Apple. This is why so many people can't stand you.

Its not senheisser fault, its apples fault, so i wont sell my headphones, i just wont buy another apple product again. Theres is no reason to drop aptx support, and do it silently. I probably will install Windows 10 on this laptop so i get aptx and 32 bit apps support like it should be on any serious product.

For me it works still OK despite reboots. Maybe you need to disable AAC via Bluetooth Explored -> Audio Options?

If your device supports both codecs then macOS might favor AAC. Now I listen via Sennheiser Momentum 2 wireless and they use apt-x no problem by default.

It behaves randomly despite whether I reboot the MacBook Pro or not. Though it seems I found the pattern. When I use my Beoplay H9 headphones at my desk in the office it shows AAC. But when I try it at home or in coffee shop it shows AptX (and the quality of sound improves significantly).

Most of the time I use 5Ghz WiFi (FYI just in case Bluetooth and WiFi modules are on the same chip). Also there might be some radio noise at 2.4Ghz in the office so the system chooses AAC over AptX.

I have the latest Bluetooth Explorer and it crashes every time exactly at the moment I open Audio Options window.

The reason of crash:

"Application Specific Information:

Performing @selector(createWindow:) from sender NSMenuItem 0x600000c3cfc0

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread.'

terminating with uncaught exception of type NSException

abort() called"

I tried to reinstall the Bluetooth Explorer and XCode. No luck so far.

The Apple Support replied to my inquiry. They say that the AptX codec support in macOS Catalina 10.15.2 is partially workable and Apple's engineers are on it to fix it.

Same here. My audio device - "Oneplus wireless bullets 2" is not even support AAC. Apple! You must return aptX support!

It looks like aptX is back since the last system update :)

Please verify and enjoy :)

Same problem... this is insane, it works in windows perfectly meanwhile i have to stick to SBC on osx... instead of getting better osx gets way worse year by year... miss old Jobs Apple so much.

I've contacted Apple support for this issue and turns out Apple dropped the AptX support on Catalina, sad

Same problem with my Avantree Audition Pro. The best OS ever uses SBC. Very disappointed.

Same issue on Bower& Wilkins P7... Very disappointed. only SBC ou AAC

Same with Sennheiser HD1. Shame.

Wait, the headphones blink with white light, which is aptX according to the manual. Mac OS claims its "SBC". But the sound is good enough and with no delays. Maybe it is just a bug in UI?

How can Apple just remove this? I mean SBC is more or less unusable
