Peachpit and Maria Langer are making available for free one chapter from her just-released Mac OS X 10.5 Leopard: Visual QuickStart Guide
and two chapters from the previous edition of the book, Mac OS X 10.4 Tiger: Visual QuickStart Guide.
The two chapters from her Tiger book, on Unix and on Classic, are still fairly current if you need to know about the topics, but we had to cut to make room for new Leopard capabilities.
You can find the free chapter from Maria's Leopard book here
The Tiger Classic chapter is here
, and the Tiger Unix chapter is here.
Maria's book is available now. You can order it here.
