fear not - you're not "stuck" - its only been four daysStill stuck on 10.8.1 for some reason. Do we know how many are still left on this version?
The beta releases tend to go out in in ever larger groups.
First batch is only small, then a larger batch and another until they roll it out fully.
After some versions that needed emergency patches its probably for the best.
For me 10.8 arrived really early, in the first 100 or so, but I don't have 10.9 yet and I was in the wide release batch at the end for 10.6
So I'm presupposing I'll be in the wide release group at the end, but that hasn't happened just yet
