Welcome to The MacNN Review's in depth look at Mac OS 9. Those who have been reading The MacNN Review for more than a year are sure to remember our Mac OS 8.5 Visual Tour which garnered more than a quarter million page loads in just a few days. I'd like to point out that the version of Mac OS 9 featured in this tour is not the final shipping version (only the probable, final shipping version) and therefore some features may be added or removed in the interim.

Navigating through this tour has been done so as to offer the best and easiest reader experience. You can navigate through the "windows" by clicking on items within them. Only items with their names in red can be clicked on for more information. Black names mean that the item hasn't undergone any real changes in Mac OS 9. Text links are also provided at the bottom of each page in case you get stuck. Finally, clicking on the phrase "Your internet co-pilot... and so much more." will take you back to the beginning of the tour.

In the coming days we will add Sherlock II to our virtual tour. Stay tuned.
