Will M1 iMac's Bluetooth automatically convert Apple Music AIFF tracks to AAC for AAC-supported headphones?

Question

Will M1 iMac's Bluetooth automatically convert Apple Music AIFF tracks to AAC for AAC-supported headphones?

Will bluetooth on a M1 iMac automatically convert Apple Music imported in AIFF to AAC via bluetooth to AAC supported headphones. If my album tracks have been imported into Apple Music in the apple codec AIFF will it automatically stream the tracks via bluetooth to my AAC supported headphones or would I have to covert them to AAC.Any advice appreciated. On a M1 iMac running Sequoia 15.6.1

No, It won't automatically convert them.

You should update to Sequoia 15.7.2 or you could wait for the 15.7.3 which will be released this month.

Hi, Yes I did the usual phonearobot ichat thing with B&W and reply was 'MAY be able to use an Apple charger as long as it is 60watts max and does not support fast charging" I've got an Apple 20W (for my iPhone 12) and a 30W (supplied with my m1 MacBook Air) chargers but don't know if either supports fast charging, as B&W reply was do NOT use a charger that supports fast charging.Very confusing for a first time wireless headphone user.You would think B&W would sell a charger that is known to be compatible.

Thanks for the swift reply, B&W PX7Se headphones arriving today and trying to make sense of which charger to use is another minefield after a ichat with B&W. Life's complicated.

You're welcome. Did you contact B&W Support about compatibility?

I would have thought it came with one.
