I almost died laughing, you, sir, are well on your way to being a great professor! The key is disgust and disdain for your students’ choices, and their existence in general!
That being said, if you don’t want to wade through the handful of differences in UI, there’s a very good chance that your school provides the software for them to run windows in a virtual machine, from whence they could follow along in the windows version of SketchUp. I know our university provides VMware and Windows for all students.
If you are looking for something in particular that you can’t find, I would be more than happy to do a quick screen recording. If you are looking for more resources, your university may offer students a subscription to lynda.com, which has good SketchUp Courses, and you could also try Bonnie Roskes’ books, they typically reference the differences between Mac and PC very well, I have used them as a textbook before.
