Mar 2, 2016 4:54 PM in response to aliendaysby judysings,★HelpfulHi aliendays,
I understand you experienced a kernel panic on your Mac, and are wanting to know what caused it. Without a little more information from the panic report or knowing what you found in the Console app, I can't really tell you. However, I can give you some basic information here regarding kernel panics and some troubleshooting steps to address them. You're already doing the most important step by keeping your Mac backed up with Time Machine.
Take care,

Feb 28, 2016 2:09 PM in response to aliendaysby Barney-15E,If it doesn't recurr, it may have been just something went astray.
If it happens again, or you just want to investigate further, post the panic log.
Open Console app.
If the list of log files isn't a howling, click the show log list button.
CLick the disclsure triangle next to System Diagnostic Reports to display the log entries for that header.
SElect the topmost log whose name begins with kernel
SElect all of the text after Anonymous UUID, copy, then paste it into a reply here.
