The lecturer will use a Windows OS laptop most of the time.
On occasion, the interface in Windows will not match the interface in a Mac.
While we will try to have examples for all operating systems, it will be useful if, when you find that the Mac view is different,
that you take a screenshot of the Mac environment and send it to the instructor.
The instructor will ensure that the Mac screenshot is integrated into the class pages pertaining to the situation in which the screenshot was taken.
