Yes, you can set it up so that your .html file opens in Text Editor instead of your default browser.

• Highlight your .html file by clicking it once
• Go to the "File" menu and select "Get Info", or simply press Command+i
• Now where it says "Open With", click the expanding arrow if the tab sin't already open
• Choose "TextEdit" from the pull down menu

Now when you double click your .html file, it will open in TextEdit instead of your browser. Now to view your page in a browser, just go to the File menu and select "Open File". Then I would bookmark the site.

By doing this, you can open your html in your editor, and save changes as you edit. With the page open in the browser, just hit "refresh" to see the changes.

I know this is an old post, but just in case there are other mac people out there besides myself.
