Mac OS X 10.4: Calculator, Unit Converter widget, and Stocks widget may not work correctly

Issue or symptom

The Calculator application, the Unit Converter Dashboard widget, and the Stocks widget rely on data from the Internet that changes daily. In some cases, they may appear to have stopped working even if there is an active Internet connection:

• When using the Calculator application, nothing may happen when choosing Currency from the Convert menu.
• When using the Unit Converter widget, the message "Data unavailable" or "Update failed" may appear when choosing Currency from the pop-up menu.
• When using the Stocks widget, stock values may be blank and the message "Error retrieving chart" may appear.
  

Solution

Download and install the Mac OS X 10.4.11 Update or later.
