I have attempted all the suggestions listed in Apps on my MacBook Pro but I still can't find the app I am looking for: Find my iPhone.
I have checked Applications, Downloads, Spotlight, Finder, and Launchpad.
I went to download it, iTunes says I have already downloaded it, have tried everything to find it on my computer. I can't find it and I cannot apparently download it again. I am completely stumped with this one and desperately need to find my phone.
