Why can't I update my iPhone to iOS 18?

Can you post a screenshot of the whole screen, it could reveal why you aren't able to update.

Make sure you:

• Are using a WiFi connection (not a hotspot).

• You have an active cell signal (You need both WiFi and cellular service to perform the upgrade).

• Are not using a VPN connection.

• Have your battery charged at least 50%. Better yet, keep it plugged in during the update.

• Do not have power save mode turned on.

• Do not have a beta version installed.

• You have at least 10 gigs of storage available.

I have an iPhone 13 Pro and an iPad Pro (5th Gen). Both continue to show "Unable to Check for Update", "An error occurred while checking for a software update." The "Try again" button does nothing. This started on other compatible devices I support on Saturday (Oct 12, 2024), with no remedy in site, unless you have a suggestion.

I currently have iOS 17.6.1 installed.

I've tried restarting my device, but that hasn't solved the issue.

I have 139GB of free space on my 256GB device, so that is not an issue.

The Apple System Status webpage is useless in this regard since it only tells you that everything is green.

It’s probably best for you to stay on iOS 17 iOS 18 is draining my battery rapidly. I have lost 10% battery within a few minutes. Just wait on the iOS 18. Wish I did.

Same problem how to fix it?

i have 15 pro max official update does not appear on my phone

Has anyone found a solution to this, still stuck with new iphone 15pro max that wont download ios 18 so wont allow me to transfer to new phone

help pls

In the Software Update screen, if you scroll down past iOS 17, there should be a small button for iOS 18.

If you have already updated to iOS 17.7, you may need to wait a few days for iOS 18 to re-appear.

I have yet to see the iOS 18 update. When I check my phone it tells me it can’t check for updates now. I have the previous update on my phone the 17.6.1. What’s happening

I have an iPhone 14 and the only option I have in my updates is the 17.7.1. There’s no option for 18. Please help us apple.

Check that you didn't overlook something. When my phone offered me a choice of iOS 17.7 or iOS 18, it led with a big panel offering the iOS 17.7 upgrade, and mentioned iOS 18 in a much smaller area at the bottom of the screen.

I think you’re ignoring our main question and our main complaint. Why aren’t we seeing that there is an update for us, obviously some people aren’t. I am not seeing that there is an update available for me. My iPad is telling me that I am up-to-date with iOS 17.7 do da.

Do you have an M4 iPad? If so, Apple has pulled the iPadOS 18 version for that device due to some serious issues. It is not available. Apple has not stated when they will make it available again.

The update was there a while back…I decided to update to 17.7…now the 18 update option is gone.

If you were trying to update a M4 iPad Pro (not an iPhone), this might be because Apple temporarily pulled the iPadOS 18 update for the M4 iPad Pro, due to serious issues.

I have not heard of the iOS 18 or iPadOS 18 updates being pulled for any other eligible iPhone or iPad.

Are you not getting the iOS 18 option?

Or does it not want to download?

What is happening exactly?

Also, what iPhone model do you have?

What iOS version is it currently running?

I get my iPhone 12 , and I get about 9 Gb free to install the iOS 18

but there is no option to install it and I can’t do it

So what happens when you go to Settings ➜ General ➜ Software Update then?

Can you post a screen shot of that screen?
