iOS 18.4 & macOS 15.4 Secretly Turn On Automatic Updates—Here’s What You Need to Know

Apple’s latest software updates—iOS 18.4 and macOS 15.4—have quietly introduced a big change: automatic updates are now enabled by default on iPhones and Macs. This means your device could download and install updates without asking you first—something many users may not realize.

If you prefer manual control over when your iPhone or Mac updates, here’s what you need to do.

Why Did Apple Enable Automatic Updates by Default?

Apple has always pushed for security and stability, and automatic updates help ensure users stay protected from vulnerabilities. However, some people prefer to wait before installing updates—especially if:

  • They rely on specific app versions that may break.

  • They want to avoid early bugs in new updates.

  • They have limited storage or slow internet.

Now, with iOS 18.4 and macOS 15.4, Apple is making automatic updates the default setting—meaning your device could update without explicit permission.

How to Disable Automatic Updates on iPhone (iOS 18.4)

If you want to keep control over your updates, follow these steps:

For iOS (iPhone & iPad):

  1. Open Settings → Go to General.

  2. Tap Software Update.

  3. Select Automatic Updates.

  4. Turn off the following options:

    • Download iOS Updates

    • Install iOS Updates

    • Security Responses & System Files (optional)

Now, your iPhone won’t update without your approval.

How to Turn Off Automatic Updates on Mac (macOS 15.4)

Mac users can also opt out of automatic updates:

For macOS:

  1. Open System Settings (or System Preferences on older macOS).

  2. Go to General → Software Update.

  3. Click Automatic Updates (or Advanced).

  4. Uncheck these options:

    • Check for updates

    • Download new updates when available

    • Install macOS updates

    • Install app updates from the App Store (optional)

Now, your Mac won’t install updates automatically.

Should You Keep Automatic Updates On or Off?

✔ Keep Automatic Updates ON If:

✅ You want the latest security patches immediately.
✅ You don’t want to manually check for updates.
✅ You trust Apple’s updates and rarely face bugs.

✖ Turn Automatic Updates OFF If:

❌ You need control over when updates install.
❌ You’ve had issues with buggy updates in the past.
❌ You have limited storage or slow internet.

Final Thoughts

Apple’s move to enable automatic updates by default in iOS 18.4 and macOS 15.4 is meant to improve security—but not everyone wants this change.

If you prefer manual control, make sure to disable automatic updates using the steps above.
