How to set buffer size on mac?

[JiminSalmonArm]

Does the frame size setting apply to the data transfer between both the audio interface/computer(JK) and the data sent out over the Internet? Or do we have no control over the Internet frame/buffer size?

This current discussion has been about the AUDIO Frame size - as set via  Manage-Audio Settings-Audio Booster.  This controls the audio frame size (somehow related to audio buffer size) for the USB audio interface.  In our quartet, changing this audio frame size can make a large difference in the Audio latency that JamKazam reports during the session.  It does not make any difference to the internet latency reported.  There is a thread in the forum "Help with Network Gear" that is discussing changing the internet settings (packet size) - but I haven't played with this yet
