Apple Aqua Human Interface Guidelines Jaguar/Panther/Tiger

Consistency is key: Apple's first Mac OS X human interface guidelines emphasized the importance of creating a consistent experience for users across all applications and system interfaces. This means using similar design elements, language, and functionality to ensure that users can easily navigate and understand different parts of the operating system.

Simplicity is essential: Apple's guidelines also stress the importance of keeping design simple and intuitive, avoiding unnecessary elements and distractions that could confuse or frustrate users. This includes minimizing the use of technical jargon and focusing on clear and concise language to communicate information.

Accessibility is a priority: Apple's guidelines highlight the need to design interfaces that are accessible to all users, including those with disabilities. This includes providing clear and legible text, using high contrast colors, and offering alternative ways to access and interact with the operating system.

Attention to detail matters: Apple's guidelines emphasize the importance of paying attention to even the smallest details in design, such as alignment, spacing, and visual hierarchy. These elements help to create a cohesive and polished experience for users.
