Installing update issues PLEASE HELP!!!

[mrsAP]

I am new to this site.....
I have been having trouble installing any updates to my macbook for the last 9 months. Im still using itunes 10 its giving me the error message unexpected error occurred. I dont know what to do I dont want to have to wipeout my entire mac as I was told at the apple store because they did not know what was wrong either. I tried intalling the 8 items that needs to be updated individually still no luck.. I even tried from apples website... Has anyone had this happen if so please help!

Have you tried reinstalling the operating system with out deleting your information? To do this hold down the option key when you boot up the computer. Then when you get to the menu click on the reinstall option. If possible try to do a back up before you do the reinstall just to be safe. I would retry the updates after you do that. Hope it helps.
