I'm trying to upgrade my computer to High Sierra (minimally) or Mojave (not ready to go to Catalina yet), but the App store links I can find for both those OS versions gives me this message (same if I go to a link for Mojave). Ideas?
Look in your Applications folder and Downloads folder for "Install Mac OS...". Find and delete all previously downloaded installers, then restart and try again.
Thanks, Macjack. That might have done it - at least it's letting me download it now and that's more than I got before. Much appreciated.
You're welcome. Good luck with install. Let us know if you have any further issues.
App Store Installer for High Sierra (and Mojave) damaged?
