This is how to install iOS 12 on your iPhone or iPad. The iOS 12.4.1 update is here with an important security fix, which prevents a jailbreak and secures your phone from nefarious apps. This is an update that many people should install right now, without waiting for Apple to prompt you.
This guide will show you how to install iOS 12 or iOS 12.4.1 without losing any data by upgrading right from your iPhone or by connecting to a computer with iTunes.
While iOS 12 and iOS 12.4 brought many new features, this update is solely about security. This may be the last update before Apple releases iOS 13 which will come around the same time as the 2019 iPhone. You can install iOS 12 on any iPhone that runs iOS 11, and if you skipped a few updates you can still install iOS 12.4.1, it just might take longer.
After you install iOS 12 you can still downgrade, but no longer back to iOS 11. Make sure you are ready to install iOS 12.4.1 by completing this list of 10 things to do before installing the update, and check out our reasons to install iOS 12.4.1 and reasons not to before you proceed.
The iOS 12.4.1 update takes about 10 to 30 minutes to complete if the download speeds are good. The iOS 12.4.1 update takes only 5-15 minutes if you are already on iOS 12. You need WiFi and the device’s battery must be at 50% or higher..
How to Download and Install iOS 12.4.1
You don’t need to wait for a pop-up or an alert to let you know that you can install iOS 12. You can download and install iOS 12.4.1 on your iPhone and iPad right now by checking for updates. If your iOS 12 download stalls, gets slow or simply won’t start you should restart your iPhone as this will often fix that issue.
With your iPhone charged to at least 50% and connected to a WiFi network, this is what to do to install iOS 12.4.1.
Make sure you have an iCloud backup or iTunes backup before you start. On your iPhone go to Settings -> Tap on your name -> Tap on iCloud -> Scroll down and tap on iCloud Backup -> Make sure the Last successful backup time and date are recent. In most cases it will be last night.

You can now enter your Apple ID password and complete any setup steps needed. This will vary and it may require you to complete a few more options and make some choices as you complete the process. If you need to reset your Apple ID password, go to iforgot.apple.com.
How to Install iOS 12.4.1 with iTunes
If you don’t like using your iPhone to download and install the update over the air, you can plug into iTunes. This is often more reliable on the first day or two of a major update, and occasionally this will find the update before your iPhone or iPad sees it.
Connect the iPhone to your computer using a Lightning cable. If you get asked to trust the computer tap on yes on your iPhone. Sometimes you will see a popup telling you that you can install iOS 12.4.1, but if not, here’s what to do.
- Click on the iPhone or iPad icon in the upper left.
- Click on Check for Update.
- Click Download and Update.
- Agree to the terms and conditions.
- When needed, enter your passcode on the iPhone.
While this is not any faster than installing iOS 12.4 right on your iPhone, it often skips some of the problems, and on the first day it can help with download speeds if your computer has a better connection.
