If there's not enough space to update

My Mac won’t turn on — now what? This may sound obvious, but check to see if your Mac has power or if its battery needs charging. For desktop Macs, a cable may have come unplugged. For older MacBook models, a degraded battery could cause problems that make it appear like it won’t boot. Hi Guys, I finally found a fix for this issue. So after waiting for almost 4 hours I gave up and force closed my Macbook Pro. I restarted it and the mac failed to boot up showing me some kernel commands. Got me really scared as I didn't take any backup of my files. These are the steps I took.

If there isn't enough space to download and install an update, the software on your device will try to make space. It will remove only app data that it can download again and doesn't remove or relocate any of your data. If your device still doesn't have enough space, you can use your computer to update your device.

If you can't connect your device to your computer, you can make room for the update by removing content and apps on your device that you don't use. Go to Settings > General > [Device name] Storage.

If the download takes a long time

You need an Internet connection to update your device. The time it takes to download the update varies according to the size of the update and your Internet speed. You can use your device normally while downloading the update, and your device will notify you when you can install it. To improve the speed of the download, avoid downloading other content and use a Wi-Fi network if you can.

If you can’t reach the update server or can’t verify the update

If you try to update your device, you might see one of these messages:

'Unable to Check for Update. An error occurred while checking for a software update.'

'Unable to Verify Update. [Software] failed verification because you are no longer connected to the Internet.'

Try updating your device again using the same network. If you still see one of these messages, try updating your device using another network or update your device with your computer. If the issue happens again after trying to update with multiple networks, remove the update.

If the update doesn't complete

If you're installing the update, the progress bar might appear to move slowly. The time an update takes depends on the size of the update and the number of files on your device.

When you're updating over the air, keep your device connected to a power source. If your device runs out of power, connect it to a power source and turn on the device to let the update or restore complete.

Remove and download the update again

If you still can't install the latest version of iOS or iPadOS, try downloading the update again:

1. Go to Settings > General > [Device name] Storage.
2. Find the update in the list of apps.
3. Tap the update, then tap Delete Update.
4. Go to Settings > General > Software Update and download the latest update.

If you don’t see the update in the list of apps or if the issue happens again, you need to update your device with your computer using Finder or iTunes.
