Apple’s iOS 14 is here. This brings over 200 new features and changes to your iPhone, including widgets for the home screen, inline replies in messages, and bike routes in maps.

So what is a GM? With Golden Masters, Apple can test software that they consider “done” for the last time. Beta testers receive the software a few days before it becomes public and give Apple one last chance to confirm that there are no major bugs or issues when the software is available to everyone. Developers can also finish off any kinks in their own software so that users can update both iOS and their apps smoothly on day one.

Method 2: Install the IPSW file with your computer

If you don’t want to sign up for Apple’s beta program, you can always install the GM seed from the IPSW file. You have to use a computer to do the job. If you’re using a Mac running macOS Catalina or later, do so using Finder. For all previous versions of macOS, use iTunes to install the file.

If you are using Windows you should try to use 3uTools as unfortunately you cannot install iOS 14 GM with an IPSW file outside of macOS. Full disclosure, we did not test the tool ourselves.

Step 1: Download the correct IPSW file

Not all IPSW files are created equal. While all of the iOS 14 GM IPSW files will install the GM, you will need to use the ones specific to your iPhone. We’ve added links below for all iPhones compatible with iOS 14. These links are verified by Apple and are 100% legit and safe to use.

Unlike Method 1, which uses the public GM, these links use the developer GM. You must have either macOS Catalina or Xcode 12 installed on your computer to use these links (you don’t need to install the full Xcode app if you install mobiledevice.pkg instead). Of course, if you happen to be a developer, you can easily download the IPSW file from the developer’s website.

Once you have the IPSW file on your computer, installing iOS 14 GM is a breeze.

Step 2: Connect your iPhone to your Mac or PC

Connect your iPhone to your computer with a Lightning to USB cable or a Lightning to USB-C cable.

Step 3: unlock your iPhone (if necessary)

When your iPhone greets you with an “Unlock iPhone to Use Accessories” popup, use Face ID, Touch ID, or your passcode to unlock your iPhone.

Step 4: trust your computer (if necessary)

If this is the first time your iPhone has connected to your computer, you will likely need to “trust” the computer to continue. Just follow the instructions on your iPhone and computer. You can trust the computer again anytime you want.

Step 5: open iTunes (or Finder on Catalina)

When your iPhone has successfully connected to your computer, iTunes should open automatically. If it doesn’t, open it manually. If you’re running macOS Catalina, open Finder and skip to step 8.

Step 6: update iTunes (if necessary)

Update iTunes to the latest software version to avoid potential problems. In macOS 10.13 High Sierra and below, you can check this from the Update tab in the Mac App Store. With macOS 10.14 Mojave, iTunes can be updated via “Software Update” in the system settings.

If you’re not already signed in to iTunes, do so now.

Step 8: choose your iPhone

When your iPhone appears in iTunes, click the appropriate icon next to the media drop-down list. Make sure you are in the Summary view.

If you want to keep your data safe, back up your iPhone on iOS 13. You can do a full backup using iTunes or Finder, or a partial backup using iCloud. Since you’re already using iTunes or Finder, it might make the most sense to back up there. If you want to save your health and activity data, select the encrypted local option and click “Back up Now”.

If you Really However, I want to make sure the data is protected …

Step 10: archive your iOS 13 backup (optional)

The next time you connect your iPhone to your computer after the backup, the old backup will be overwritten with the current status of your iPhone. Usually this works fine. However, since you’re running iOS 14, it means your computer will overwrite your old iOS 13 backup with it. Not good.

If you want to make sure your iOS 13 backup is safe, or if you want to downgrade to iOS 13 again, you need to archive your backup. This may sound a little difficult, but it can be quite easy.

To archive using iTunes, open Settings, select Devices, right-click your iOS 13 backup, and select Archive (you should now see a lock next to the backup).

If you’re using Finder, select “Manage Backups” from the “General” tab, right-click the iOS 13 backup and select “Archive” (the name of the backup changes slightly to demonstrate that it was saved).
