How Did Apple Change

Macintosh File System vs. BSD UNIX File System
Macintosh File System vs. BSD UNIX File System. Why did Apple change? In order to find this answer I had first understand the two technologies and their background. Lets begin with Macintosh Operating System’s first file system named Hierarchical File System. Hierarchical File System was introduced in 1985 to support Apple’s first Macintosh model that contained a hard drive. The Hierarchical File System was created to overcome the performance issues with Macintosh’s original file system Macintosh File System. Macintosh File System was originally designed for floppy disk and small amounts of data storage, so it only made sense to replace the file system with adequate technology. (Cranston, July)
BSD is the Berkeley Standard Distribution. In the early 1980s, the University of California at Berkeley was a major center of focus of UNIX activity. They adapted AT&T 's System III and provided more sophisticated process management and network functionality. They distributed their version of UNIX, called the Berkeley Standard Distribution, for what amounted to the cost of goods. This, in turn, was widely adapted by academia and turned into the source material for further innovations by companies such as Sun Microsystems.(Babcock, August) This file system has been developed and has seen performance increases derived from significant improvements in technology from research. The Unix File System being open source technology allowed for the increase in advancements due to outside influence from other research groups and developers as well. UNIX has been around the 70’s, which is obviously longer than the Steve Jobs and his group from Palo Alto,
