I want to update my mac mini OS from Maverics to EI Capitan.

When i click on Get button at that time it will give a error message. For better understanding i attached screen shot of the error message.

Also i attached screen shot of the mac mini configuration.

I tried with removing cache folders from the /private/var/folders path but not working.

In above path i found folders, which name is 7s and zz. Also remove the folder which name is com.apple.appstore for remove the temporary files.

Please provide appropriate solution for upgrade the mac os.

  • I guess you already canceled the download, closed the App Store completely, deleted the folder contents, opened the app Store again and restarted the download? – Kevin Woblick Oct 5 '15 at 12:01
  • Yes, i do these steps but not working. The same error becomes when click another time for download. – sn86 Oct 5 '15 at 12:34
