Okay so somehow I accidentally deleted iPhoto from my Mac. While in Launchpad I noticed that two iPhoto icons showed up. Both would open the app. Only one copy of iPhoto appeared in my Applications folder. So I figured it would not be a big deal to delete one icon in Launchpad. However once I did it seems to have deleted iPhoto from my Mac. Is there anyway to get it back? I do have my HDD backed up using CCC. Would it be as simple as copying over iPhoto from the external HDD? Or can I re-download it from the Mac App store? Please help. Thanks.
