I just re-installed OS X 10.1 and when I check the software update it says my software is up to date which is not of course. I had saved 10.1.x updates but whenever I try installing one it asks me to run "INSTALLER UPDATE" which I had also, so I ran it but when it asked me to chose a partition and they are all greyed. Because of that I'm blocked and can't go any further... Help would be much appreciated, I can't remember having that issue before, maybe a problem with the apple software server which cant detect my OS version !?
