No, never solo for me. A backpack is a lot more enjoyable with the company of friends and I'm lucky enough that my wife enjoys backpacking, so I have at least one companion.
That said, I once met a group of people hiking the Rae Lakes Loop (start from Kings Canyon Roads End or Onion Valley). There were about a half dozen, all started out solo, but met up while hiking along the way. They all seemed to be enjoying themselves a lot.
I day hike a lot alone, or with my dog, who is surprisingly good company. I've also done several road trips alone when I was single, but a backpack is awfully quiet by yourself. Just my preference, I guess.
As for safety, if you stick to reasonably frequented trails you should be OK. This assumes you have good route finding skills.
