Cognos 10.2 is being replaced in Fall 2019. The new version should be compatible with Safari.
Notice Create Date: April 22, 2015
Notice Update: [none]
Problem: This bug prevents Safari users from selecting among the full set of Excel options for report output.
Summary: While running Safari in Cognos 10.2 when you select an option to view a report you may notice the 2007 and 2002 Excel options are not available.
Resolution: Since there is no current work around and until the bug is corrected, for Macintosh users who require an Excel option, it is recommended these users access Cognos 10.2 through Chrome.
