Reply To: “Keychain cannot be found to store app” prompt while installing Mac app


Is this happening for all your Macs? It sounds like a device-specific problem that has something to do with the keychain. Each user has a default keychain for user login. The kind of error you mentioned could occur if –

  • The user’s password does not match the password of the login keychain (old password persisting in the keychain).
  • If the system found no login keychain (keychain not created during user creation).
  • Sometimes it might also occur when you change or reset the password from the login window.
  • The user is missing access permission to read and write to the Keychain/Application folder.
