How to Fix Error 3194 on iTunes

Everyday users download and save files, make videos and take pictures, install apps and programs. At the end of the day, the Mac becomes cluttered with memory hogging files and programs that are rarely used after they are installed.

The iPhone was designed to save files for you until you need them. Downloaded files, videos, and applications can be massive in size; therefore, if you aren’t using them, delete, delete, delete! This tutorial will show you how to free up space on your Mac so that you can perform an iTunes backup for your iPhone.

Update Your iOS Software

Apple provides several updates each year for iPhone and iTunes. Make sure you have the latest version of iTunes and that your device is up to date. Also, prior to making any serious changes to your iPhone, first make sure that the software is up to date.

1. For iPhone users, go to Settings > General > Software Update.

2. If any new updates are available, choose to update them.

3. You may want to restart your phone after the updates if you are not prompted to do so.

Free Up Space on Your Mac with Reduce Clutter

If you have begun to receive the Your startup disk is almost full notification, it’s time to free up some space on your Mac

One option is to move some of your files to an external hard drive or flash drive. Or, you can move some of those files to the Cloud.

You must create backups of your data from time to time. So, if your Mac is full and you can’t use iTunes, you will have to decide how you will manage future data. Most likely, you have loads of old and temporary files that you no longer use. You can try to delete unused large files from your Mac. You can clear your cache so that those old files will be removed automatically. Or, you can use Reduce Clutter:

1. Go to Apple > Storage > Reduce Clutter

2. Select Review Files button and choose a category from the list in the sidebar. You can choose Applications, files, iTunes, and such.

3. View the total storage space the file is occupying on your Mac.

4. You can choose to delete the entire file or delete files that are within the file.

Apple > Storage

5. Go to Apple > Storage and manage your files.

6. You can also free some space on your Mac using cursory find-and-delete to manage the large files, including some large downloads.

7. Create a new disk or partition on your Mac to handle the extra files.

Empty Your Trash

Most of the files that you drag to the Trash are actually still somewhere on your computer. The way to truly delete these files and clear up space on your Mac is to empty your trash.

Manage Your iCloud Storage

Store in iCloud

Store in iCloud is a feature in iOS 11.4 and later. When this feature is activated, much of your data is stored in iCloud as backup automatically:

Your iCloud saves much of the messages, media, and app data from your iOS device, which could grow to become a massive file. After some time, the 5GB may no longer be enough. If you have used all of the iCloud storage, it no longer backs up your iPhone data. To find out if your iCloud has any bearing on the problem, manage your iCloud storage by following these steps:

1. Go to Settings on your device

2. Go to Apple ID > iCloud > Storage & Backup.

3. Look to see if you have enough storage space to perform the backup.

4. Select Manage Storage and tap Backup.

Check to see if clearing up storage fixed the problem

Note: After iCloud has stored 5GB of your data, the use of the storage service is no longer free. The service starts at around 50GB additional for $0.99.
