Mac & MacOS Help

A reader writes:

I have a Mac running OS 10.3.5, and I am trying to use TextEdit to write HTML code in your example. However, it will not let me save the file with an .html extension, as you specify needs to happen for the browsers to properly read it. And I tried it anyway using both .rtf and .txt extensions (the only options it will allow), and Explorer says “it doesn’t know how to handle the type of file you’ve selected.” Of course, I didn’t expect it to work, because your book said it wouldn’t. What can I do? And will I continue encountering problems as I go through your book since I’m working on a Mac, and the book is written from the perspective of PC users? Thanks
