Regarding that KP, I came home from work after the second day of having it running (so I assumed) but it was sleeping.... well, press the space bar to wake it and though the computer did, the screen never changed from blank. I assumed crash/KP? After rebooting can't recall if it was clover or Mac but I do recall a screen stating something along the lines of the system had a kernel panic an blah blah blah.... sorry I can't be more help on that as at that time it wasn't priority as a reboot calmed everything. With that being said I'm assuming the KP happened upon wake maybe? (if it was KP'd already it should've technically been crashed and unable to respond to me pressing any keys correct?) But since we are starting to simply fine tune things on our ends (us X299ers) with apple constantly releasing updates that's turning our machines more of the native, I will definitely keep aware for the next time it happens. I leave my computers running all the time though they do sleep.
