The book has a lot of useful information, but it can seem out of date. It focuses on OS 9 and gives only lip service to OS X (a brief ten page chapter 14 added to the end of the book). It's location of files and preferences, etc assumes OS 9. Once in a while mention is made of OS X's differences when describing the location of files (such as Easy Setups). But not always, which is confusing (for example, the location of plug-ins and preferences files is different, but you won't know that unless you go to Ch 14 and see if you can find something on them.) Another example, it offers advice on installing FCP on a partition with its own System Folder and special extension set to avoid conflicts. The unsaid assumption is that you are in OS 9. Is there any reason to follow the same precautions in OS X? (we don't have extension sets there, remember?) We'll never know--at least from this book. Further, it sometimes describes an older version of FCP - for instance, it mentions the Preferences settings window as having 5 tabs. Sorry. Has 6 now, and not all with same names. Screen shots all are from OS 9 (except for a few in Ch 14). If you're using X, I'd look for something more current.
