This has happened a few times over the years but more frequently. Lately, I'll be using my 13" Macbook Air (2014) and for no reason I can figure out, the entire system will freeze, the screen will go black, and then I will be logged off and returned to the login screen. I have no warning this is happening and no way to stop it. After logging in again all the applications have been closed applications and any unsaved work is lost. I also have no way to MAKE it happen.

Pretty sure this isn't Security and Privacy issue as it happens while I'm browsing or watching a video or sometimes mid-keystroke. I also don't think its a overloaded or taxed by excessive RAM demands by the programs in use, just basic browser, chat, WP and video.

Any suggestions would be helpful. Thanks.

    @Fayaz After a reboot the last ten lines will contain messages from the boot process, not the crash – nohillside Jul 13 '18 at 5:46
