Idle Lightroom Classic - high CPU usage Mac

Question

Hi!I run High Sierra 10.13.3 and Lightroom Classic 7.2 on my MacBook Pro 15" 2017.When idle Lightroom always uses a lot of CPU (around 100% of my CPU). I've checked that any processes for syncing or face detection is paused and I even re-installed the Lightroom and reset the preferences. Still uses a lot of CPU while idle.(I know that many have had problems with CEPHTMLEngine but in Activity Monitor I don't see that it's running high. It's only the app "Lightroom" in activity monitor that runs high on CPU)How can I fix this?Thanks in advance!Regards Simon

Check activity monitor to see if spindump and tailspind  also have high CPU usage.If they do, then what may be happening is that when Lightroom uses a lot of CPU, then spindump becomes active to aid analysis of memory usage and it turns into a sort of vicious circle consuming CPU. Unless you are a developer you probably don't need spindump and tailspind running.You can disable spindump and tailspind by following the instructions here:Disable tailspind and spindump to Speed Up your Mac - The Mac ObserverAfter doing this, my idle-time Lightroom CPU usage has dropped from 100%+ to around 2%.Paddy
