Hi everyone. I've run into issues with restoring iPhone apps to/from my phone backup in iTunes, so I thought I'd see if someone might be able to help. For reference, my iPhone is a 5s running iOS 9.0.1, and I'm using iTunes 220.127.116.11 on a MacBook Pro running Yosemite. I noticed that there were a number of apps in the Music/iTunes/iTunes Music/Mobile Applications that I no longer have installed on my iPhone, so in the interest of freeing up a little extra disk space on my MacBook Pro, I wanted to rebuild my app archive from scratch. I deleted all of the apps in the Mobile Applications folder, then the plan was to use the File > Devices > Transfer Purchases from [my iPhone's name] function to re-copy all of the apps from my phone to my iTunes archive, thereby leaving me only with the apps I'm currently using. Unfortunately, after deleting all of the apps from the Mobile Applications folder then re-connecting my phone and using the "Transfer purchases" function, only a few items seem to transfer (a few songs I've purchased on iTunes), and that's about it. For some reason, I can't get the apps on my iPhone to copy back to the iTunes archive, and the Mobile Applications folder remains empty. To make things worse, I have a brand new iPhone 6s that I'd like to start using, but whenever I try installing the backup of my 5s to my new 6s, almost all of the apps are missing. I think the key is for me to restore all of the apps on my iPhone 5s to the Mobile Applications folder. Once that's done, I should be all set to successfully restore the backup of my 5s to my new 6s. So, any suggestions would be appreciated. On a side note, am I correct in assuming that iPhone backup file(s) don't contain apps? In other words, it seems like restoring a backup is contingent upon having all of the apps in the Mobile Applications folder, in which case the apps aren't stored within the backup file itself.
