roughly half that size (that is, around 4MB) while sounding almost as good.Most people don’t notice much (if any) difference in audio quality when listening to music on typical consumer audio gear. So unless you expect to hook your iPhone up to a great pre-amp and amplifier and superb speakers or headphones, you probably won’t hear much difference with this option enabled, but your iPhone will hold roughly twice as many tunes. Frankly, now that we can subscribe to Music and stream virtually any song, we don’t store a lot of music on our iPhones.
And, of course, if you decide not to select the Automatically Sync When This iPhone Is Connected check box, you can synchronize manually by clicking the Sync button in the bottom-right corner of the window. Note, however, that if you’ve changed any sync settings since your last sync, the button is Apply instead of Sync.
Syncing Your Data with iTunes or Finder
Now that your data is backed up and you’ve completed the prep work, you’re ready to sync. The next order of business is to tell Finder or iTunes what data you want to synchronize between your iPhone and your computer. You start this process by clicking Info in the sidebar on the left side of the iTunes window or near the top of the Music app window.
Moving right along, the Info pane has three sections: Sync Contacts, Sync Calendars, and Advanced, described next.
Syncing contacts
The Sync Contacts section of the Info pane determines how synchronization is handled for your contacts. One method is to synchronize all your contacts. Or you can synchronize any or all groups of contacts you’ve created in your computer’s address book program.
The iPhone syncs with the following address book programs:
Mac: Contacts and other address books that sync with Contacts, such as Microsoft Outlook
PC: Windows Contacts, Windows Address Book (XP), and Microsoft Outlook
Mac and PC: Yahoo! Address Book and Google Contacts
Now, here’s what each option in the Sync Contacts section does:
All Groups (Catalina or later) or All Contacts (Mojave or earlier or Windows): One method is to synchronize all your contacts in your Mac or PC address book with your iPhone’s Contacts app.
Selected Groups: Enable this option to synchronize any or all groups of contacts you’ve created in your computer’s address book program. Just select the appropriate check boxes in the Selected Groups list.
Add New Contacts from This iPhone To (Catalina or later) or Add Contacts Created Outside Groups on This iPhone To (Mojave or earlier or Windows): Enable this option and you can choose a group from the pop-up menu. Then, new contacts created on this iPhone will belong to the group you chose.
Syncing calendars
The Sync Calendars section of the Info pane determines how synchronization is handled for your appointments and events. You can synchronize all your calendars, or you can synchronize any or all individual calendars you’ve created in your computer’s calendar program; just select the Selected Calendars option and then select the appropriate check boxes.
The iPhone syncs with the following calendar programs:
Mac: iCal and Calendar
PC: Microsoft Exchange and Outlook 2016 and up
Mac and PC: Google and Yahoo! Calendars
Advanced syncing
Every so often, the contacts or calendars on your iPhone get so screwed up that the easiest way to fix things is to erase that information on your iPhone and replace it with information from your computer.
If that’s the case, just click to select the appropriate check boxes at the bottom of the Advanced section of the Info pane (at the bottom of the Info tab). Then the next time you sync, that information on your iPhone will be replaced with information from your computer.
One last thing: If you’re using iCloud and you want to replace the contacts or calendars on your iPhone, you must first enable the item in Finder or iTunes. To do that, you first have to disable iCloud syncing on your iPhone for Contacts and Calendars (as described in the section “A Brief iCloud Primer”), and then enable the check box for Sync Contacts or Sync Calendars in iTunes or Finder as we’ve just described.
Synchronizing Your Media
If you chose to use your computer to manage synchronizing your data, welcome back. This section looks at how you get your media — your music, movies, TV shows, podcasts, video, and photos — from your computer to your iPhone.
