Ask HN: The "coreaudiod" process uses waaay too much resources on
macOS. why TF?
hey all, so this drives me nuts really. on a brand new M1 machine I
am using the Spotify desktop app. it consumes around 2.6% of the
CPU (with some minor fluctuations). the coreaudiod process though,
uses 13.6% of the CPU (with some minor fluctuations). does anybody
have an idea why the audio process uses so much resources? (on my
previous machine - Macbook Pro 2015 - that was definitely not the
case)
