Some Mac users have reported technical issues once they update their OS to the High Sierra Update. To be precise, their App Store feature is not working as it should or at least, as it did before the update. Usually when an app releases its update, it is directly indicated in the App Store, but in this case, you get the update and when you proceed to download it, you get a pop-up showing “No Update Available”. Sometimes, the main culprit could be a ghost update.

My Mac Won't Update Software

1Shut Down and Restart Your MacBook

This is often the first action to any issues with an Apple device. Before attempting any troubleshooting protocols or tech mysticism, it is recommended that you shut down the system first. Wait a few minutes and reboot the system. It is possible that the increased load to the processor immediately after the update may trigger its misbehavior. Once you restart your machine, the App Store will start recognizing the apps that need updating and those that are up to date.

Remember, do not restart the system, shut it down and give your processor and OS a fresh start.

2Change App Store Settings

If restarting your Mac doesn’t work, your next recourse should be the App Store Settings. You’ll have to change some of them and try to solve the issue.
The first stage is to launch “System Preference” and from there, open “App Store”. On the “automatically check for updates” option, toggle it on as well as all the options therein.

Your system will then begin searching actively for any app updated including the system updates and they will also be downloaded and installed automatically, as soon as you turn all these options on.

You can also check the “app is updated automatically”, and close the App Store app and re-launch it after a few seconds. It will display the message: “Mac app store says no updates available”.

Click on Check Now after a few minutes and do either of the following to see if this fix has worked or not.

1. Check internet connection.
2. Check App Store Purchases.

If you have unwillingly logged out from the App Store with your apple id, no new updates will be installed on your Mac. However, you can still log in to your system with your login credentials and proceed normally with the updates.

3Check Update with Terminal – Force Update

Using Terminal should be the last resort and shouldn’t be attempted carelessly. Always use precaution when working with Terminal. Ensure you have administrator privileges, i.e., admin passwords to effectively execute commands. To check update with the terminal is also considered a force update and should be done in the following way:

From the terminal, execute the following command “sudo softwareupdate –ia”. A message “Finding Available Software”, will be displayed once you execute the command. All the updates should appear on the screen and to install them, type the following command “Sudo softwareupdate – -install – -all”.

If your system is still unresponsive, one last course of action should be typing the command “defaults read com.apple.appstore” and execute it. This command should unmask the issue behind update not showing in App Store.

4Clean Cache of App Store with Finder

Now for this fix, we’ll employ the use of ‘Finder’. Launch Finder and simultaneously press command + shift + G keys.

Alternatively, you can open “Go Menu” and select “Go to Folder”. Then type the following command '~/Library/Caches/'. Go to the filename “com.apple.appstore” and delete it from the folder.

Go back to the top and open 'Go Menu' > 'Go to Folder' but this time, type /private/var/folders and locate “com.apple.appstore” in all the folders and subfolders, then delete it.

Restart your Mac, and hopefully, the issue will be resolved.
