Object Pascal was needed to support [[MacApp]], an expandable Macintosh application framework that would now be termed a [[class library]]. Object Pascal extensions, and MacApp, were developed by Barry Haynes, Ken Doyle, and Larry Rosenstein, and were tested by Dan Allen. Larry Tesler oversaw the project, which began very early in 1985 and became a product in 1986.

An Object Pascal extension was also implemented in the Think Pascal [[integrated development environment]] (IDE). The IDE includes the compiler and an editor with [[syntax highlighting]] and checking, a powerful [[debugger]], and a class library.<ref>{{cite Many developers preferred Think Pascal over Apple's implementation of Object Pascal because Think Pascal offered a much faster compile–[[Linker (computing)|link]]–debug cycle, and tight integration of its tools. The last official release of Think Pascal was 4.01, in 1992. [[NortonLifeLock|Symantec]] later released an unofficial version 4.5d4 at no charge.magazine

Apple dropped support for Object Pascal when they moved from [[Motorola 68000 series]] chips to IBM's [[PowerPC]] architecture in 1994. MacApp 3.0, for this platform, was rewritten in [[C++]].
