Updating your iPhone is essential to keep it secure, improve performance, and access the latest features. Sometimes, updating directly on the iPhone can be problematic due to storage issues or connectivity problems. In such cases, updating your iPhone using a computer is a reliable alternative that many developers and users prefer.
This guide explains how to update an iPhone on a computer using iTunes or Finder, depending on your operating system. You will learn practical steps, troubleshooting tips, and best practices to ensure your iPhone update process is smooth and error-free.
What is the process to update an iPhone on a computer?
Updating an iPhone on a computer involves connecting your device to a Mac or Windows PC and using software like Finder (macOS Catalina and later) or iTunes (Windows and older macOS versions) to download and install the latest iOS version. This method bypasses the need for over-the-air updates and can resolve update errors on the device itself.
By using a computer, you can also back up your iPhone before updating, which safeguards your data. The computer downloads the update file, verifies it, and installs it on your iPhone, ensuring a stable and complete update process.

How do you prepare your iPhone and computer before updating?
Before starting the update, preparation is key to avoid interruptions or data loss. First, ensure your iPhone has enough battery life or keep it connected to a power source during the update. Next, close any unnecessary applications on your computer to free system resources.
Check that your computer’s operating system and iTunes (if applicable) are updated to the latest versions. This ensures compatibility with the newest iOS update. Also, disable any VPNs or firewalls temporarily that might block the connection to Apple’s update servers.
Finally, create a backup of your iPhone using Finder or iTunes. This backup protects your data in case the update encounters problems or fails. You can choose to encrypt the backup to save passwords and health data securely.
