No kernel panics. However, my console log has this repeated over and over:
04/11/2016 14:54:27.000 kernel[0]: Sandbox: SpotlightNetHelp(350) deny(1) file-read-data /Applications/Image Capture.app
In addition to Image Capture, it shows the exact same with Mail, Messages, Mission Control, Notes, Photo Booth, Disk Utility, Digital Color Meter, Grab, Grapher, Migration Assistant, Terminal, etc etc. This was shortly after yet another reboot this afternoon, if that matters, and everything is fine for now, so it doesn't seem related.
Nothing unusual to report in Activity Monitor, other than Gmail tab using 666.6MB (and Safari in general using A LOT of RAM). My available memory stays pretty stable at 14GB, doesn't jump up over the day because of swap files.
I setup EtreCheck on "beachballing" and below is the output. I have just removed the file it recommended and will be rebooting after posting this.
