After reformatting my hard drive, I lost some of my apps and have to pay to get them back. What do I do?
My OS got corrupted, so I had to reformat my hard drive and in the process lose all the data on my hard drive. This includes apps that were included in my MacBook when I first got it such as Facetime, while others are at their pre-Yosemite versions. I can't reinstall them since I have to pay for them, while the other apps like iMovie and Garage Band can't be updated and also require payment. How do I get these apps back? I use a Late 2013 MacBook Pro Retina 15" running on 10.10.1. Bought it at around February or March 2014
MacBook Pro with Retina display, OS X Yosemite (10.10.1)
