• On startup I get an iCloud login request saying that cookie 5 was bought on a different computer. Logging in doesn't start Cookie. If i try to start after that i get no response at all. I'm running OSX El Capitan 10.11.6

  • that sounds like its something to do with the Mac app Store.

    maybe try move Cookie to the trash
    then log in to your Mac App Store account
    then re-download Cookie.
