Why is an approval stamp not appearing on my consent?
If using a Macintosh, you may have a compatibility issue.
The myIRB stamped templates are compatible when running Microsoft Office 2004 for Mac with Update 11.3.3 or a later version of Microsoft Office for Mac. For more information about this or other updates refer to: http://www.microsoft.com/mac/downloads.
Additionally, the Mac must be set to open and save the stamped template as a .RTF file. Typically, the default setting on a Mac is to open .RTF files using a text editor (such as Macintosh Editor or WordPad), but the stamp can only retain its functionality when opened using a full word processor like Microsoft Word. It may help to download the template without opening it, save it to your Mac, open Microsoft Office for Mac then navigate to the template and open it.
If the above suggestions do not relieve the problem, you may want to visit the support page for Microsoft Office for Mac at http://www.microsoft.com/mac/support. Or if you have Mac support, you may want to visit http://www.apple.com/support/ to contact the Genius Bar (the Apple Product user support service).
Updating the software and adjusting the settings on a Mac will prevent the issue from occurring when using other templates in the future, but it is likely the tokens that allow the stamp to work have been damaged. To fix the existing document you will also need follow the directions for Replacing a Damaged myIRB Approval Stamp.
