Not sure if this is the right forum or not but after I installed 10.6.6 on my MacBook Pro mid 2010 a lot of my applications are not functioning properly. Firefox crashes constantly (though redownloading it seemed to fix it) but my main issue is that iTunes does not work. First, it lost the XML file for my library. After reinstalling iTunes and recovering the XML file from a backup, it will now load but constantly crashes after about 20 seconds. My Mac Pro doesn't have any of these problems while running 10.6.6. Any ideas? Edit: it says the Library was damaged so, again, I am trying to get an older file to fix it. Anyone else having issues like this after 10.6.6? Edit #2: Now it will not let me go and recover files from Time Machine. Notnsure what thisnupdate has done to my computer.
