Enable Aptx codec on Mac

I have a issue about enable the aptx codec on my mac. My devices are Macbook pro 2016 and Mac pro2013. They should be able to ture on aptx automatically and they do on Macos 10.14(Sometimes AAC sometimes Aptx) but after I upgrage to Macos 10.15 only AAC is working. I try different ways on web to enable aptx but they didn't work, for example

"sudo defaults write bluetoothaudiod "Enable AptX codec" -bool true"

Or the app "Bluetooth explorer"

It shows" "Enable AAC codec" = 0;

"Enable AptX codec" = 1;"

But it is still using AAC codec.

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.
