Mavericks has also made ALL my Macs useless.
I believe you, but....
It seems many members of Apple forums (not just this one) simply refuse to accept reports such as "everything was fine until I installed Mavericks", even though we see such reports over and over and over again, on an almost daily basis. On the Apple Support Forum it's almost hourly.
I've spent a good bit of time on religion forums over the years, and it's remarkable how many of these threads read just like that.
Some fellow Mac user sincerely reporting a Mavericks related problem is likely to get a series of replies like this....
It couldn't possibly be the infallible Holy Mother Ship that is the problem. It must be the user's fault, or some other developer's fault, or bad luck, or maybe the Devil did it! The Holy Mother Ship is working fine for me, and that's proof that you are wrong. Watch out that you don't become an blaspheming apostate heretic!
Really guys, it just gets to be too much after awhile.
Couldn't we just believe the poster,
who knows far more about their situation than we do, until such time as we have
specific evidence which indicates their theory might be incorrect?
In another thread on this forum
an Apple programmer who is working on Mavericks honestly disclaimed that Mavericks was full of known bugs, but Apple released it as ready anyway. He was apologizing, because he knew this wasn't the right thing to do.
Good for him. I feel bad for all those sincere truly professional people working at Apple who are put in such an embarrassing position by others up the chain in the business and marketing departments.
And
THAT is why so many people are coming to Mac forums reporting problems with Mavericks.
Mavericks was released full of known bugs.
It's NOT the user's fault.
It's NOT bad luck.
The Devil didn't do it.
It's Apple's fault, as reported by someone within Apple in a position to know.
I'm not suggesting we should all therefore hate Apple.
I am suggesting that users reporting Mavericks problems deserve the benefit of the doubt. Their problems are real.
