My 2015 retina MacBook had a number of crashes earlier this year. I would open it up in the morning and would get the "your computer has restarted due to a problem" screen. It happened every night, plugged in or battery didn't seem to have any effect. The report to apple screen had what looked like kernel panic messages. In the end I bit the bullet and did a clean install of OSX and that solved things, until this week. The same issue has re-occured. All I have on the machine is office and the rest is via iCloud as my iMac is my main machine this is just for when I am out and about. Any ideas on how to prevent this issue or should I goto a genius bar?
