You don't need WINE, or Windows, or Cross Over. Just Safari.
Launch Safari, click on the Safari name on the top bar, then Preferences. On the Advanced tab there is an option for "Show Develop menu in menu bar." Check it.
Now, on the top bar of the screen when Safari is running is an option for "Develop" and under that is an action item "User Agent." Pick that and select whichever browser you want. There are options for IE 7,8,9,10 and 11.
Safari will now report that it is whatever version of IE you selected and the other end should be happy.
