Borland did not ignore the Macintosh market entirely, with early efforts including Turbo Pascal 1.0, Sidekick, and Reflex porting for Mac. However, development stopped in 1988 due to market size and differences. Turbo Pascal, Borland’s main product, was optimized for CP/M rather than GUI-based systems like the Mac. Mac development required complete UI rewrites and faced hardware limitations. Despite Borland’s technical superiority, they lost out to Microsoft due to late Windows support. Borland’s low prices appealed to a wide range of users, but they missed the opportunity to capitalize on the Macintosh market, where other vendors flourished with specific Pascal compilers.
