I was not in safe mode and while it’s being itself I am trying to send this. But the advice given is beyond me! I don’t really understand what I might or might not be doing. Just what my Mac to work and not misbehave.

Update on my kernel panics. After lengthy discussions with the good people at AppleCare we decided to restart in Recovery mode, erase the hard disk and reinstall the OS. That was done but did not make things any better. It was such that my Mac was unusable! After more discussions and thinking, I discovered a Lion Install disk filed away. So I restarted in El Capitan then proceeded to install Lion. That took a loooong time. I then installed over Lion, Yosemite. my Mac being 2008 it struggles with El Capitan. I reinstalled critical software and now I HAVE NO MORE KERNEL PANICS!! Not sure why but it's no longer falling over. Great. Maybe I'll be a new Mac one day!
