Editing Apple Adjustable Keyboard (section)

== Development Context ==

The Apple Adjustable Keyboard emerged during a period of heightened awareness about repetitive stress injuries (RSI) in the computer industry. By 1992, multiple lawsuits had been filed against computer manufacturers alleging that poor keyboard design contributed to carpal tunnel syndrome and other musculoskeletal disorders. Apple's response was to develop an ergonomic solution that would address these concerns while maintaining compatibility with existing Macintosh systems.

Development began in 1992 with a focus on reducing wrist pronation and ulnar deviation—primary contributors to RSI. The design team studied existing ergonomic keyboards including the Kinesis Advantage and early Microsoft prototypes, ultimately settling on a split design that balanced ergonomic benefits with user familiarity. The keyboard was positioned as a premium accessory for professional users who spent extended periods typing.

Apple's timing coincided with increased corporate interest in workplace ergonomics. The Occupational Safety and Health Administration (OSHA) had begun developing ergonomic standards, and employers sought solutions to reduce worker compensation claims related to RSI. The Adjustable Keyboard targeted this market segment with claims of reducing typing stress through its split design and neutral wrist positioning.
