I received an excel sheet from one of our customers. It's protected, but as a vendor, we're supposed to be able to access a hidden section to enter our products. When I open the sheet on any PC, I get a warning that says "you are about to access confidential information, do you agree?" or something like that, and I get to the hidden part. When I open it on my mac, I'm asked to enable macros, but that agreement page doesn't apppear, and I can't view the info. Is protection handled differently on the Mac? This is Excel 2004 by the way.
