Back Up iPhone on Mac with macOS Mojave or earlier

On a Mac with macOS Mojave 10.14 or earlier, things aren't changing. You can continue to use iTunes to backup, update or restore your iPhone. The process is basically no different than that via Finder. Here's how to back up iPhone to iTunes with Mac.

• Plug your device to your Mac machine.
• Open iTunes, and click iPhone icon on the top left of the window.
• Click Summary on the iTunes sidebar.
• Enable "Encrypt local backup" if you'd like to make a full encrypted backup of iPhone to Mac.
• Choose Back Up Now.

If iPhone isn't backing up to Mac, try the following:

• Make sure you have the latest version of iTunes on the Mac. In the menu bar, click Help > Check for Updates. If you get the ''A newer version is available. Would you like to download it now?' messages, click Download iTunes to update it instantly.
• Check that you have latest iOS on the iPhone. Go to Settings > General > Software Update. If there's a new iOS released, tap Download and Install.
• If you're prompted there's not enough free disk storage, free up space on Mac. Delete the apps you seldom use and the useless files.
• If you're prompted the backup is corrupted or incompatible, update your Mac. From Apple menu, choose System Preferences, then click Software Update. If any update is available, click Update Now.

Employ an iPhone Backup and Restore Tool (All Mac Machines)

Generally speaking, Apple's Finder and iTunes are reliable, and they make managing iOS device easier without intervention. If you use one of them for backing up iPhone files to Mac, then you should know it does not allow you to access the backup files straight away, unless doing a restore.

In other words, if you're concerned about flexibility, it's not a bad idea to install an iPhone to Mac backup software program. A better one-stop option would be iOS Data Backup & Restore.

The flexible utility sorts the files on iPhone's memory into different directory items as long as the phone is connected, and allows you to back up everything in a suitable way: Standard Backup or Encrypted Backup. It's only an a-few-minute job and doesn't require tech skills. Once the iPhone is backed up, you could certainly move the folder into an external hard drive so it doesn't take up space on the Mac machine.

Once your device is backed up, the program will enable you to restore certain files to the device or desktop without losing anything. This is the powerful restore feature shipped with the utility.

To get the most from the software and back up iPhone with Mac, you will need your device unlocked, a USB cable, a Mac computer with iOS Data Backup & Restore installed. Now we'll illustrate the instructions.

Step 1: Connect iPhone to Mac (desktop & laptop)

Once you get the application set up in Mac, launch it. On the opening window, click "More Tools" option, then choose "iOS Data Backup & Restore" tab to get to the next screen.

Then, click "iOS Data Backup" tab to continue.

Next, you're now required to connect iPhone via a lightning cable. Do it and then click Start button.

Step 2: Back up iPhone to Mac (MacBook Air, Pro, iMac, etc.)

In the window that opens, locate types of files you intend to back up, or copy to Mac: photos, videos, messages & attachments, voicemail, Notes, app documents and so on.

Click Next button and let the application do its business.

Do other USB things work in that port?

Have you checked for iTunes Updates on the Mac, I think there was an update to handle just such cases.
