It used to be that you could keep useless clutter out of syslog by creating/editing /etc/asl.conf. However, this seems to have changed in Sierra. See here: https://arstechnica.com/civis/viewtopic.php?f=19&t=1319619 Right now I'm trying to suppress this useless garbage in the console: Code: WindowServer No matching context for device (0x7fe353328620) - disabling OpenGL This appears ~50 times/sec in my log and I wish it gone. I tried creating this asl.conf: Code: ? [= Sender WindowServer] ignore and then restarting syslog/rebooting, but to no avail. Anyone know how to shut WindowServer up and keep it from wearing out my SSD?
