Every time I click the update button to update my Mac software, a pop up shows up - An error occurred while loading the update (102).

I don't know what to do; I can't update my software. I hope you can help me.

Launch Terminal and type the following command if you are running macOS Sierra:

 open `getconf DARWIN_USER_CACHE_DIR`/com.apple.appstore

Move all the files and folders out of com.apple.appstore. Then relaunch Mac App Store.

You can delete all the files and folders later if Mac App Store works well. ‚Äč

  • In addition to providing a path to resolve this problem, it would be for your answer to include some info as to why your solution will work. This helps both the OP and others who have the same issue and who are not willing to just run Terminal commands without knowing what it will do. – fsb Oct 10 '16 at 13:50
  • The path is dynamic. It's different in everyone's Mac. So I can't give the exact path. It's the quickest way to find the folder with command. – Vincent Oct 10 '16 at 14:19
