Differences between earlier and more recent Mac operating systems

The Mac OS X operating system differs greatly from earlier Mac OS versions in that it accommodates files using a conventional three or four character file extension. Prior to OS X Mac files were listed by the type/creator method. When attempting to recover Mac files one needs a program that will be able to recognize both file types. This creates a situation where to recover Mac files we must essentially have two data recovery tools built into one. Plus that same tool needs to be able to recognize universal file types such as document and image files.

Programs for Mac recovery are far more complex than those used on Windows. This complexity is reflected in the prices for Mac data recovery products. Still if ever there was a situation where you get what you pay for this is one. Many data recovery companies claim that their file rescue tool will work on both Windows and Mac computers. In truth these programs can only locate Windows files on Mac computers that happen to use certain Intel microprocessors.
