iTUNES STUCK AT PREPARING (2 of 4) WORKAROUND:
Here's what I do and it works 100% of the time:
1. Plug in iPhone, attempt to sync.
2. When it's stuck at 2 of 4 Preparing: Click the X (#1 in pic) in the info-box, then click the sync icon (#2 in the pic), which will turn into an X on hover.
3. It'll now stick on cancelling sync. Wait about 5 seconds, then unplug the iPhone.
4. Wait for iTunes to stop cancelling sync (about 10-15 seconds).
5. Plug in iPhone again.
6. Click Sync and it should now fly past 2 of 4 and go to 3 of 4 rapidly.
7. Sometimes I need to press sync a second time if it decides what to sync but then doesn't actually sync the items.
Let me know if this works for you too! Thanks
(If it works for the majority of people, maybe it should be stickied 🤷♂️)
