I have had reported on occasions when Safari on Mac is downloading a PDF from one of our sites it will append .EXE to the end of the file. The MIME type is correctly set to be pdf but it still does it occasionally.
I have found http://support.apple.com/kb/TA24293 which seems to indicate that this is a known issue with Safari on Mac however as official as this is (Since it is from Apple themselves) our clients don't seem to want to believe it. So I want to know if there is a solution to this problem?
I say "occasionally" because we have some Macs that this is happening on and some it's not. So maybe it's a setting or something, it downloads perfectly fine in IE, Firefox, Chrome and even downloads fine on mobile Safari. It is just Mac Safari.
