Hey everyone,
I noticed that you are having problems with the version number too.
This happened to me as well when I was using 10.0.3 and had to re-install os 10.0.0 from disk because of a younger sibiling

. After downloading 10.0.1, 10.0.2, 10.0.3 from the software updater which I guess wasn't too smart in the first place because I could have just looked in my reciepts folder,
the version for the os was messed up.
After some work in sherlock I FOUND the receipt folder and installed the newer versions of OS X and the problem was fixed. Unfortunately this was the not the end if my problems.
Now, whenever I update my software, the time which shows when the updater was last run is an hour off. exa. if I updated the software on Mon 9:11 PM it would show up as Mon 8:11 PM
Any Ideas?
