Recently (the last three day) my late 2013 iMac has been suffering from kernel panics. After reboot, console shows a 'Previous shutdown cause: -62'. Can someone please tell me what this means. The only thing I have changed is I added a new backup drive (2TB external). It seem to only happen after about ½ hour after wake (from sleep). It only does it when doing multiple processes, like running photoshop, iTunes open in background, youtube vids playing etc. So, any ideas. Any help would be appreciated, Thanks, BR

So you're advised to troubleshoot your system for any stuck application, startup item and any loading preferences. Re-install macOS also may help.
