How to find out what version of iTune and iPhoto I have?
For each application, launch it and choose About from that application's menu, or control-click its Dock icon, choose Show in Finder, control-click that, and choose Get Info.
In your Application Folder... Right Click on the said Applications... Select Get Info Version...
iPhoto 8.1.2 under Application folder
I probable delete the iTune.app
Probably, It will be better if I bring my iMac to Apple store.
If you are confused and/or unsure about what you are doing or want to do that is a very sensible idea.
