I sat down at the old (and I do mean old--3 years, an eternity by technostandards, I guess) MacBook this morning after a break of a couple of hours and discovered that I could not access anything, though the thing would boot up and show my home page, tantalizingly, it would not respond to cursor directions.
So the Macfolks have been called, they've advised various treatments which didn't solve anything and ultimately I decided that I will take it into town on Monday for either a new hard drive or (gasp) a new laptop. I have been saving up for just this very moment, when I am needing more from the MacBook than the MacBook can provide quickly. I won't go for the fancy model, but I will get the AppleCare plan so that future repairs will be less expensive.
Mac really is the only way I want to go but a laptop gets carried around enough that shaking and knocks and bumps can lead to needed repairs. It's been in the shop twice in the past 3 years and both times needed a new hard drive. At least I've gotten wiser about backing up; I have almost everything saved safely somewhere.
So I'll be offline for most of the next couple of days. Sorry, just in case you're feeling bereft. Call me if you're lonely!
