Mojave update iMac 2017
I have some apps open and around an hour in everything starts to get sluggish. This didn't happen before. I have adgaurd running globally on the iMac and that's it. Im running Folx pro and safari. Eventually everything goes sluggish. Running OS off an external thunderbolt SSD. Something has changed. Under optimize Ive turned off everything. Off I assume is not blue? Switched to the left?
