The whole "app thinning" thing as the reason for the lack of a backup
and sync issue seems like a total cop-out.
There is no reason on God's green earth that you cannot keep a separate library
backup up with the proper apps for the proper devices on the computer. It seems to
be simply an excuse for lazy programmers who don't what to be bothered with how
the users "really want things to work". After all, Apple has each of our devices stored
in their databases and knows who owns what. They also have the separate versions
for different devices on their servers as well (otherwise how can they download device
specific apps!)!!!
The fact that my apps updated/downloaded on my iPhone don't sync to the computer
pretty much defeats the purpose of backup and syncing, doesn't it????
Also, for what its worth, automatic download of music to all devices also no longer works.
For the past year, I have had a MacMini set up as a file server and an iTunes Home Sharing base.
In the store preferences, I have had, and always have had the Automatically download check boxes
checked on it. The server always has iTunes running and is always logged in.
Yet, recently I had purchased a couple of albums on one of my Macs and I synced it to my iPhone
(before iOS9 or iTunes12.3) and all was good for them. I recently just looked at my server, and iTunes
did not automatically download these albums and only shows they are available for download from
the cloud. Why even bother putting in "automatically download feature" that no longer work!!!!!!!
Maybe I am old fashioned or something, but I thought the purpose of backups and syncing
was to be able to restore a device back to its original state should something go wrong!!!!!!!!!!!!!!
Not just "sort of" back to original state!!!
