When you click Software Update on your iPad or iPhone, you'll see 'Unable to Check For Update.' It's a slightly extreme way to prevent software updates, but some users may be determined to keep. Dec 10, 2014  When you turn off the pre-release software update seeds option, you will no longer receive notifications about these updates. However, rest assured that your system will work just fine and you will also get update notifications for major updates that are out of beta.

This constant reminder from Apple to update your device to iOS 12/11.4/11.3 can be a pain and if you want to get rid of it, choose when you update your device rather than have Apple decide for you, you’re in the right place. Here, we will discuss the various ways you can get your iPhone or iPad to stop sending you these “reminders” all the time.

Before we get to the solutions, it is however necessary to let you know that there is no easy solution. After all, Apple wants as many people as possible installing the latest iOS update (it is iOS 12 for now). So much so, that they have introduced a new feature that downloads the update in the background and then the device sends you these “reminders” to install it once the download is complete. In essence, you are getting these reminders because the updates have already been downloaded and are just awaiting installation.

1. Delete the Downloaded Update from Your Device

1. There are several ways to turn off update notifications on macOS, depending on how you want to deal with these updates. Method #1: Disable Notifications Temporarily. If you want some peace and quiet for until midnight only, you can pause the alerts via the Notification Center.
2. Open software update; Click 'advanced.' (bottom right) Unclick 'check for updates' Command + Q system preferences. Turn off internet. Reopen system preferences. Reopen software update. Here are those steps in photos: Step two (red dot!!) - Open software update: Step three - Click 'advanced.' (bottom right).

If you delete the automatically downloaded iOS 12/11.4/11.3 update, there should be no more reminders to update. Here’s how to do it.

Step 1: Tap on Settings.

Step 2: Tap General and then Storage & iCloud Storage.

Step 3: From there, tap “Manage Storage” (below “Storage” not “iCloud.”)

Step 4: Find the iOS update. It should be the one with iOS then followed by numbers.

Step 5: Tap “Delete Update” and again in the alert window that appears.

2. Block Apple Updates from your Wi-Fi Router

Actually even you delete the iOS update, it will still download the latest iOS 12/11.4/11.3 when your iPhone is connected to Wi-Fi and so you will receive the update alert again. You can block Apple Software Update Domains on your router to keep them from accessing your device. The process will depend on the router you are using. But it typically involves opening your router’s web-based interface and find “Domain Blocking” or “Domain Block.” Enter the domain apple.com.

Here’s what the process would be like using a Virgin Broadband Router as an example.

Step 1: On the Safari browser enter the Mac address from the admin site. You can find it on the back of the router.

Step 2: Enter the password which can also be found on the back of the router/modem.

Step 3: Click “Advanced Settings” and then select “Domain Blocking” under “Parental Controls”.

Step 4: Add appldnld.apple.com into the Domain to Block and then click “Add Domain.”

Step 5: Add mesu.apple.com and then click “Add Domain.”

Step 6: Finally, click “Apply” and “Yes” and you should never receive any updates from Apple.

Note: This will prevent software updates from working. If you check for an update, you will see “Unable to Check for Update.”

Tip 1: How to Turn off Automatic Updates

Turn Off Apple Update Notification

Remember how we said, you get the alert because Apple has a new “Automatic Update” feature that downloads the updates for you. The good news is, you can disable this feature and should never be able to get the alert again. Here’s how to do it.

Step 1: Launch the settings app on your device and the tap “iTunes & App Stores.”

Step 2: Turn “Automatic Downloads” off.

Tip 2: How to Downgrade iOS 12 Beta to iOS 11

If you have upgraded your iPhone to iOS 12 but you don’t like it and would like to downgrade it to iOS 11, then you can learn how to downgrade iOS 12 Beta to iOS 11 from the article. However, downgrading iOS to old version is never an easy task and you need to follow the instructions tightly.

You should stop receiving the alerts of iOS 12/11.4/11.3 update once this is done. Just to be sure though, delete the updates that were already downloaded.
