Performance slow down after LR is open for a while, Mac OS Sierra

[toddv97178392]

I've noticed that if I leave LR open and unused for more than a couple of hours when I return to use it it runs unacceptably slow. Restarting LR solves the problem. I am using a 2013 15" Mac Powerbook Pro with 16gb memory and a 1gb SSD. I don't notice any performace problems with any other application. Curious if anyone else has noticed this issue.

You could try the solution mentioned is this linked thread Lightroom 2015.6 Painfully slow since update

Also, make sure your copy of lightroom is up to date.

I’m running current versions of LR CC and Mac OS. I had previously read through that thread and tried the pertinent ideas. And my issue didn’t exactly match any of the posts, hence my new thread. I do appreciate your suggestions though!

Please state exactly what actions in Lightroom are slow.

Also, please answer these questions:

1. Are you doing a lot of brushing and/or spot healing?
2. How big is your monitor in pixels?
3. How big are your images in megapixels?
