  • Go back to the Safari menu bar, click Develop and select User Agent
  • Select Other
  • Paste in the following user agent string:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9) AppleWebKit/537.71 (KHTML, like Gecko) Version/7.0 Safari/537.71

After clicking OK the Yahoo page should reload and you will not be prompted with the upgrade notice during future logins.
