Every time I open software update and I click on install updates, it begins the download for iPhoto 9.4.2 (currently the only update I have left), but then it stops and says that it is corrupt so it can't finish the download. I have attached an image of the exact message I get.
Any ideas on how to fix?
-reset PRAM and SMC
-verify and repair disk permissions
