From Win to Mac, Need Textbook Help

I teach four sections of high school Computer Applications. The course is primarily focused on the Microsoft Office applications, digital citizenship & ethics, and computer/Internet basics. Now and in the past, we have been on a Windows platform. Next year, we'll be providing our students Apple Macbooks as part of our new 1:1 program. In the past, I've used the Shelly Cashman Series, but it appears it's only a Windows-based outlet.

Do any of the computer teachers out there have a textbook/reference suggestion for teaching such a course on the Mac OS with Office '11? If so, I would much appreciate your advice! Thank you in advance.
