Welcome to the Support Communities!
The first thing I would suggest to open the Applications folder on your Mac. In the Utilities folder you will see the Disk Utility application. Follow the instructions below to Repair Permissions on your internal hard drive.

Restart your computer and see if that resolves your issue. If not, you may need to drag the iTunes application to the trash and redownload it from our website:
Apple - iTunes - Download iTunes Now

I hope this information helps ....
Have a great day!
