Re: How do sync your iPhone?
My husband has a Macbook Pro from 2011 and his hard drive crashed.
He had been adamant about not backing up to icloud and only backing up to his computer... You can imagine that now, he's suddenly become a huge fan of icloud back up, lol. He's lost a ton of things which he cannot retrieve.
Live and learn.
As for me, since coming back to Apple, I have discovered something very simple:
If you set up your Apple devices to work as Apple intended them to, they really do work like a charm.
In my case, this meant buying more icloud storage space, but it was cheap and I'm glad I did.
I also set up automatic back ups because I'm a noodle head who keeps forgetting.
And I do not have any problems with either my Macbook Air or any of my other devices. Life is good.
