Apple seems to be having a LOT of problems. Their iWatch is not even as good as a poorly designed high school software project.,
Anyway, I have an iPhone 5S and my friend has the 6, both with the latest iTunes. Neither of us can select the manual Update selection. It is greyed out.
Frankly, I don't think they test their software with users, and the kiddies who work there developing updates to their software are clearly not interested in actually testing their work -- they've been told how perfect they are, how everyone gets a gold star even if they do a poor job. This is a sign of the times folks.
Now, you'd think Apple has enough money to actually hire competent software developers who realize they are NOT perfect, that they DO make MISTAKE, but oh no, apple employees must think they are superior beings and that we, as lowly "USERS" (said with a very sarcastic snide inflection) should like what they produce, and not complain.
Welcome to the plantation again, with the "Boss" man telling us what to do, what to like, how to behave, etc., Sounds like the liberal agenda to me.
Obviously this manual backup problem has been around for a long time, and still hasn't been fixed, and now they tell users not to upgrade to the latest iOS because they haven't fixed the problems.
I figure you cannot go back to an earlier, FUNCTIONAL version of iTunes, so I've gotten a program called "iExplorer" that works getting music off the iPhone, iPad, etc., can save all your text messages in separate PDF files for each conversation, can save your call list, and is far better than iTunes for backing up your iPhone, iPad contents.
My guess is that the folks who created iExplorer are either former Apple employees who grew tired of the teeny bopper mentality that seems to pervade the Apple developer group, or are just smarter than the Apple developers. What do you think??
