Updating iPhoto
I updated my Mac OSX recently and my iPhoto doesn't works because of the old verison (9.3.2). My friend helped me to install the iPhoto when I buy the Mac. App store requires me to give her password insted of mine. I do not have her password. All Apple ID in the Mac is under my ID expect of iPhoto. Is there any way to update it without her password? If I can do so, will my photo library lost? Thanks a lot.
MacBook Air, OS X Mavericks (10.9.2)
