So in comparing the playback on an older Mac (2017) vs. and even older Lenovo Thinkpad (2013) I do notice that the playback progress moves more smoothly from left to right on the PC. For some reason, on the Mac it seems to move somewhat haltingly (the sound is fine but it just seems to carry with it the slightest delay on the roll) Is that a setting issue on the Mac or is it something endemic to the Mac Core audio? It is ever so subtle and as I said does not seem to impact audio quality.
Thanks!
