Get your iPhone and Mac in syncSyncing iPhone to Mac was a regular activity just a few years ago. With faster mobile speeds, more space, great streaming apps like Spotify and Listen, and more people syncing their data with iCloud, the need to physically sync isn’t as great as it used to be. Particularly once Apple made it so that iOS updates didn’t have to run through iTunes on your Mac.

But, let's face it, we still want to add movies, music, and TV shows to our iPhones. We also want to save our photos and videos directly to our Macs from time to time. That’s when we need to sync our iPhones with iTunes.

In this guide, we’ll reveal some best practices for syncing. We also have some secret tips for maintaining a clean and optimized Mac that is free of junk cache files generated during syncing.

How to sync iOS devices with Mac

Syncing iPhone with Mac via cable

The most common way to sync iPhone to Mac is with the cable that came with your phone. Use this cable to connect your iPhone to your Mac and then launch iTunes (if it doesn’t launch automatically) to start syncing your media.

iTunes doesn’t just help you sync your media. Here are some other popular syncing options to get the most of your iPhone and Mac:

  • Sync notes from iPhone to Mac
  • Sync iPhone contacts to your Mac
  • Sync messages from iPhone to Mac
  • Sync Mac calendar with iPhone

These are easy to sync in iTunes or by turning on iCloud sync in each app. A little more challenging is how to sync Outlook calendar with iPhone.

Recently, Outlook 2016 had problems syncing with iTunes but the problem seems to have been resolved. Just make sure everything is up to date.

To sync Outlook calendar with your iPhone follow these steps:

  1. Make sure the iTunes plugin is added to Outlook plugins (File > Options > Add-ins > COM Add-ins). Note - Outlook 2016 doesn’t use the plugin to sync anymore so it won’t be there for this version.
  2. Connect your iPhone to your Mac and launch iTunes.
  3. In iTunes click on your iPhones name and then click on the Info tab.
  4. Scroll down to calendars and choose the calendars you want synced.
  5. Click Apply.

The same method can be used to sync Outlook contacts with your iPhone - just look for the Contacts section on the Info tab.

Sync Mac and iOS devices over Wi-Fi

iPhone Sync to iTunes over Wi-Fi

If connecting your iPhone to your Mac via a cable feels like a strait jacket, you can now break free by setting up a sync through your Wi-Fi connection. That’s right, no more looking for cables. If only we could charge this way as well…hey Apple, what are you waiting for?

There is a downside to this freedom; the speeds won’t be as fast as when connected with a cable. But if you value convenience over speed, let’s get to the steps you’ll need to setup wireless iPhone sync with Mac.

  1. Unfortunately you’ll need your USB cable to set up Wi-Fi syncing for the first time.
  2. Connect your iPhone to your Mac via your cable.
  3. Launch iTunes and click on the iPhone icon.
  4. Click on the Summary tab.
  5. Under Options check the Sync with this iPhone over Wi-Fi box and click Apply.
  6. Now you can remove the cable. Freedom is at hand!

That’s it. Now, in future, when your iPhone connects to the same Wi-Fi connection it will be available for syncing in iTunes.

Now go ahead and throw that iPhone cable in the trash!*

*Don’t do that. That’s a terrible idea.


Clean up iTunes Syncing Cached Files

How to sync iPhones to iTunes? Solved!

Now let’s look at some iTunes tips and tricks to solve other iTunes problem – its love of wasting space.

For every good thing iTunes does it seems to generate unnecessary junk (it can be photos caches like images copies from iCloud, music caches like duplicates from iTunes, movies files caches from media players, or download histories of iOS devices); junk which it won’t clean up itself. With a few easy steps you can clean up after iTunes to free up space on your hard disk and make your system faster.

clean up iTunes backups after syncing iPhone with Mac

Remove iTunes Backups

iPhone backups can take up a lot of space. You may find that you have old backups that aren’t needed anymore or a current backup that you’d like to move to an external drive or the cloud to save space on your system.

Luckily this is not hard to do.

  • Open iTunes Click Menu > Preferences > Devices
  • Control-click the backup you want and show in finder to then move it somewhere else.
  • To delete instead, highlight the backup and click Delete Backup.
  • Confirm

You can also use CleanMyMac 3, which is a specialist Mac cleaning app that is brilliant for removing iTunes junk. It even has a section called iTunes Junk!

clean up old iOS updates from your Mac

Remove Old iOS Updates

If you update your phone by syncing your iPhone with iTunes, instead of running the update from the phone itself, then you’ll probably find that iTunes has kept the old iOS setup files. After the update, these files serve no purpose other than to annoy you when you discover how much space they are wasting.

To manually find these old iOS update files navigate to ~/Library/iTunes/iPhone Software Updates and move them to the trash.

Alternatively, to automatically remove old iOS updates and other iTunes junk, CleanMyMac is the one-click solution. It only removes files you don’t need, which gives peace of mind for those who worry about doing something wrong.

clean up broken downloads

Remove Broken iTunes Downloads

It’s frustrating enough when an iTunes download fails. But it’s even worse when you realize this download, which you can’t even use, is taking up your precious hard drive space. Thankfully, removing broken downloads is as easy as it gets with CleanMyMac 3.

Within CleanMyMac you will find a Smart Clean scan as well as a specialized iTunes Junk scan. Either option will quickly hunt down your broken downloads and present you with the option to remove them from your system with a single satisfying click.

clean up Photos cache files

Remove Photos Cache

Cache files serve a purpose, increasing the speed of certain actions, but the real world impact is minimal. With all the syncing that occurs today, you may not realize just how many cache files are being created without your knowledge.

One of the worst offenders is Photos, so if your Mac is low on space one of the first things to look at is your Photos cache folder. You’d be surprised how big it can get. One solution is to delete the cache folder. Your actual library photos will remain untouched.

To remove your Photos cache files:

  1. Open Finder and control click on Pictures > Photos Library and click Show Package Contents.
  2. Drag the Photos Cache folder to the trash.

Important Note - Manually deleting the cache folder could potentially cause a corruption of the Photos app. A safer and easier solution would be to download and install CleanMyMac 3.

To use CleanMyMac to safely remove your Photos cache files:

  1. Download, launch CleanMyMac
  2. Select Photos Junk in the left menu
  3. Locate your library and click Scan
  4. Click Clean

Remove Duplicates

Speaking of photos, once you start using multiple devices it’s very easy for your iPhone photos to get backed up and duplicated all over the place. Things can get messy very quickly, and an iPhone sync with Photos just complicates the process even more.

Manually looking through your system for duplicate photos is a nightmare. Instead, try a Gemini 2 The Duplicate Finder. It will quickly scan your system and present all your duplicate photos, making it incredibly easy to choose what stays and what goes.

It’s not just duplicate photos that you can get rid of. You can also use the app to scan your iTunes library for duplicates of songs that you’ve accumulated over the years.

You’ll be amazed at how many of them are hidden all over your Mac, and how much space you can free up. As with CleanMyMac, Gemini is incredibly safe. In fact, if you remove a photo by mistake, it can easily bring that photo back from the dead.

Sync and Swim

When we know we have to sync our Mac with iPhone, it can feel like a chore. We hope that this guide has given you the tools to make syncing iPhone to iTunes much easier and more productive. Not just for you but also for your Mac, which will surely benefit from a good iTunes cleaning from CleanMyMac, Gemini, and the manual tips we revealed in this guide.
