Are you trying to install iOS 18.5 Beta 4 but running into unexpected issues? Well, this is a pretty common problem that crops up after almost every software update. Therefore, you shouldn’t fret over the hurdle. Fortunately, there are 6 proven ways to fix the iOS 18.5 beta 4 not installing problem. Having said that, let’s track down the roadblock and get rid of it – sooner rather than later.
Fix the iOS 18.5 Beta 4” Not Installing Issue
What’s preventing the iOS 18.5 beta from installing on your iPhone? Though the sluggish internet connection is always the prime suspect, things like the clogged storage up and the jam-packed servers are equally responsible. So, you will need to look at the problem from various perspectives.
1. Check Your Internet Connection
First and foremost, it’s important to remember that a weak or unstable Wi-Fi connection can easily interrupt the update process. Since the iOS updates require a strong, stable internet connection for smooth downloading and verification, be sure to tick off this key requirement without fail.
- To get going, make sure you’re connected to a reliable Wi-Fi network (not mobile data).
- If needed, restart your router if necessary.
- After that, try moving closer to the router or switching to a different network.
- Then go to Settings > General > Software Update and check for updates again.

2. Free Up Storage Space
Check if your iPhone is low on storage. If your device is running low on free storage space, the update might fail to download or install. Yeah, you got that right! iOS updates typically require at least 5–7GB of free space during installation.
- On your iPhone, head over to Settings > General > iPhone Storage.
- Now, go ahead to delete large unused apps, offload data, or clear media files.
- Once you have cleaned up the software, update the software again after making space.

3. Force Restart Your iPhone
It’s worth mentioning that at times the update fails to go through due to temporary system glitches. A force restart often works wonders in clearing out minor issues and refreshing the update process.
- For iPhones with Face ID: Press and quickly release the Volume Up, then Volume Down, then press and hold the Side button until the Apple logo appears.

- For iPhones with a Home button: Hold down the Home button and Power button simultaneously until the Apple logo shows.
Then head back to Settings > General > Software Update and try again.
4. Use a Mac or PC with Finder or iTunes
If the over-the-air (OTA) update still won’t work, I’d recommend you manually update your device using a computer.
- To do so, connect your iPhone to a Mac or PC.
- On macOS Catalina or later, open Finder. On Windows or older macOS, use iTunes.
- Select your iPhone and click Check for Update.
5. Sign Out and Sign Back Into Your Apple ID
Sometimes, an issue with your Apple ID authentication can prevent beta updates from appearing.
- On your iOS device, navigate to Settings > [Your Name] > Sign Out.

- Now, restart your iPhone.
- After your device has restarted, sign back into your Apple ID and check for updates again under Settings > General > Software Update.
Make sure you remember your Apple ID password before signing out!
6. Reset Network Settings
No solution as yet? Keep in mind that the corrupted network settings can interfere with the update process. Resetting them often resolves unseen connection issues.
- On your iOS device, navigate to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- Enter your passcode and confirm.

- Your Wi-Fi networks and passwords will be erased, so reconnect to Wi-Fi after the reset.
- Try updating again once you’re reconnected.
Beyond these handy troubleshooting tips, make sure your iPhone is compatible with iOS 18.5 Beta and is connected to a strong Wi-Fi network with at least 50% battery (or plugged in). If all else fails, consider waiting a few hours — sometimes Apple delays beta rollouts regionally or temporarily pulls them to fix bugs.
