with Mac i5 2012 and Catalina 10.5.7 with neural mix the fan have max speed.....

mmmm I think thet the latest version 3.2 with old Mac and Catalina is no good the fan system is very high

and the stems sometimes glitch

yeah, mine is acting up as well…never thought it might be an overheat issue.
seems to be time to update hardware, then…apple refurb store, here I come!

UPDATE - bought an M3 iMac and couldn’t be more pleased. it hasn’t hiccupped once running djay. may this machine continue to run for over a decade like its predecessor!

It sounds like your Mac’s fan is running at maximum speed due to high system usage, likely from running Neural Mix. This could be because your Mac’s hardware (i5 2012) is struggling to handle the workload, especially with newer software like Catalina. Try closing unnecessary apps or resetting the SMC and NVRAM to see if it helps manage the fan speed.
