Again, if you do this, no device on the network will be able to install any update from Apple at all, nor check for available updates.
Don’t do this unless you know exactly what you’re doing and why, it’s truly only an option for advanced users, network administrators, and sysadmins who need to manage devices on their own without the constant update reminders.
This might be true, but we could not make it overgeneralization, thus you can make the decision by yourself, and we will also help handle the repeated i OS update reminder.
When your i Phone, i Pad or i Pod touch has automatically downloaded the firmware package, you will be sent a notification that you can update the system of your i OS devices.
Are you holding off on updating to i OS 11.3, and are tired of seeing the update notification on your i Phone?
Deleting the available i OS update from the device will stop the update reminder from appearing, but you have to disconnect from wi-fi and avoid wireless networks because the moment your device is unattended and back on wi-fi…
the i OS update will download itself again and start pestering you again.
Fortunately, the Mac has a bit more control for getting software updates to stop bothering you in OS X, or you can just turn on endless Do Not Disturb mode as a workaround for handling relentless notification harassment in OS X.
Perhaps a similar approach will be available to i OS at some point, or better yet, a settings option to stop the i OS auto-update and auto-download behavior entirely.
