I don't have a Mac. The day will come (maybe) but in 30 years of working with Personal Computers, the only Apple I used was the Apple ][.
So once in a while, I encounter participants that bring a Mac along and the menus look different or items have different menu positions.
Today we couldn't find Insert > Textbox easily. Microsoft assures me it's there.
Also because I am so used to Windows's Right Click, that's Control + Click on the Mac.
