Any clue what it means?
(Plenty of RAM, Plenty of disk space.)
Just means that permissions in your folder are wrong, I think; in my experience this is harmless, and restarting Unity often fixes it.
Yeah, I’ve gotten that once or twice, and after I restarted Unity it went away, so I didn’t think too much of it.

It’s starting to happen pretty consistently – it hasn’t caused any problems but I don’t like to see any warnings or error messages
That could be worrisome, yep. Have you run Disk Utility?

I just did – I’ll see if the problem goes away.
