iMac powering down / sleeping and Roon

[stephen_pritchard1 (stephen pritchard)]

I installed Roon core on a friend’s hispec iMac (i7 and 32 RAM), it works well but sit suddenly turns itself off.
I have tweaked the iMac’s energy saving settings and told the Roon software to keep its screen alive but it still periodically turns itself off.

Does anyone have any suggestions on how to keep the iMac awake and running?

Apple Folk ... how to keep iMac awake?

I’m going to try using an external hdd to hold my music, instead of my NAS. I hear that will speed up finding new music, right? But my 2019 Mac keeps falling asleep. I checked the box that tells it not to, and enabled network access, doesn’t seem to work. Any thoughts ? Am I doing something wrong? The iMac seems to work well as a core but I want it always available without having to wake it up. Thanks!

Amphetamine/caffeine?

On later versions os macOS, caffeinate is built in, so I use the following command from a Terminal window:

caffeinate -d
