If you already installed FPC under a previous Mac OS X/OS X/macOS version, you will have to reinstall FPC 3.2.0 under macOS 10.14 to get a configuration file that enables the.
The download statistics indicate that the snapshots below are still downloaded a lot. Note that all fixes from those snapshots are also in the official release of FPC 2.2.2 (and will be also in later versions, when they become available), which was released in August 2008. Since FPC 2.2.2 also contains many additional fixes, we recommend you to use that version. It is available from the regular download pages.
2007-11-14:There are some errors in the new linker shipped with Xcode 3.0/Mac OS X 10.5. A detailed overview was posted to the fpc-pascal mailing list. We have worked around most of those issues and created (stable) development snapshots for both PowerPC and Intel. These are intended to be installed on top of the 2.2.0 release version. Future releases will have these fixes incorporated.
One linker bug cannot be completely worked around in the compiler, which is related to the Stabs debugging format. For this reason, we recommend to switch to the Dwarf debugging format on Mac OS X 10.5. On the command line, you can do this by using -gw instead of -g to generate debugging information. In the Xcode projects, add -gw at the end of the FPC_SPECIFIC_OPTIONS project setting for the Debug configuration.
2006-08-27:Regular snapshots of FPC 2.1.1 (both for PowerPC and for Intel - the latterdenoted as i386) are now generated by and available from the Lazarus team.
If you only need the compiler (to either use it from the command line or from Xcode),you only have to download and install the 'fpc' package.
2005-12-18:
Version 2.0.2 that was released a few weeks ago has all fixes and improvements of the 2.1.1 snapshot that was here (like Mac Pascal style objects and creationof dynamic libraries). Additionally, it doesn't suffer from the installationproblems the 2.1.1 snapshot installer had. Get the release here.
2005-07-23:
The 2.1.1 snapshot that was here is no longer available.

If you really need to be up to date with FPC,please consider using Subversion, and build the compiler by your self.
Some changes:
- No more '_main' symbol in the system unit (so can link with C main programs)
- Shared library creation support under Mac OS X
- Several bugfixes related to overflow checking on PPC
There is now a wiki page covering porting issues, from traditional mac pascals to FPC.
2005-06-21:
A FPC 2.1.1 snapshot is available here (10.8 MB, does not include the PDF documentation). It includes:
- Support for Macintosh Object Pascal in Macpas mode (includes support for mixing in Delphi-style OOP programming in Macpas mode, except that you have to use 'object' instead of 'class' everywhere -- all occurrences of 'class' are simply internally replaced by the _OBJECT compiler token)
- Fixed bug which caused stack corruption in procedures receiving floating point parameters and parameters on the stack (only if the caller side was compiled by FPC)
- Fixed bug in overflow checking of integer operations (some calculations were buggy if overflow checking is turned on, which is the case in the default development building style of Xcode if you use the integration kit)
- Fixed bug in division of unsigned numbers > $7fffffff by a power of 2
2005-05-15:At last !!!!! Free Pascal 2.0 is released for Mac OS X and classic Mac OS,as well as for other targets.
This means Free Pascal for the mac is not considered beta anymore.Get it on one of the mirror download sites.
Targets on the Macintosh:
Target / Processor | Status | Remark | Contact |
|---|---|---|---|
final | For Mac OS X | ||
final | Target Mac OS means classic Mac OS, up to System 9.x. Although it of course also work in the classic environment in Mac OS X | ||
Mac OS on M68K | not planned | If someone is interrested to contribute, there is a possiblity to implement this target. There is support for MC68000 in the FPC source code, although not updated for a while. |
Mac Pascal dialect
Pascal For Mac Os Downloads
The dialect of Pascal supported by popular Pascals on Macintosh is supported in part. Read more here.Free Pascal 2.0 for Mac OS X is the current release. It should at least work on Mac OS X 10.1 and higher. It requires that you have installed XCode from Apple, to have assembler, linker and make tools available to fpc. For older versions of Mac OS X you should install Apple Development Tools instead. Both can be downloaded for free from Apple, but requires that you register yourself as a member of Apple Developer Connection. Both are also included in the Mac OS X bundle.
To download, go to the Download page, and choose a mirror site near you (to limit net traffic). The documentation is included, but can also be downloaded separatelly. If you want the source code, it has to be downloaded separatelly.
There most recent FPC 2.1.1 snapshot is available here (10.4 MB)with, among others, support for mac style object pascal. See above under NEWS.Note that the compiler is a unix style program and is run from the Terminal on Mac OS X.
Please report any bugs encountered.
Using FPC from XCode
It is possible to use Free Pascal from within XCode (Mac OS X 10.3 is required).Look at the step-by-step instruction of how to download and install the XCode Integration Kit. Thanks to Rolf Jansen for this contribution.Free Pascal 2.0 for Mac OS is the current release. It will work on latest classic Mac OS (that is 9.2.2) and below, probably down to 7.1.2 (the first Mac OS for PowerPC), and also in the classic compatibility environment on Mac OS X. However it has only been tested on Mac OS 9 and Mac OS X classic environment.
It requires that you have installed Macinstosh Programmers Workshop (MPW) which can be downloaded for free from Apple.
To download, go to the Download page, and choose a mirror site near you (to limit net traffic). The documentation, as well as the source code (if you need it), has to be downloaded separatelly.
Note that the compiler is an MPW tool.
Please report any bugs encountered.
Current status of classic Mac OS
Native FPC compiler (as an MPW tool) | Almost complete | |
Unit System.pp | Complete | The system unit is implicitly used by every program. Contains basic file and memory handling among others. |
Unit Dos.pp | Complete | Contrary to what its name suggests, the DOS unit is cross plattfrom and contains utility routines for file and date handling, beyond that in System.pp. It is reminiscent from Turbo Pascal. |
Unit Sysutils.pp | Planned | A moderner alternative to unit DOS, compatible with Delphi. |
Unit MacOS | Complete | API to the Macintosh Toolbox |
Units strings objpas heaptrc getopts etc | Implemented. | They are target independent. |
Other units | Non-existent. Some will be implemented. | Implementation will depend on how important the unit is and if difficulties arise. |
Debugging
There is some limited possibilities to debug programs in classic Mac OS. See MPW debugging in the wiki.
As an alternative, you might do the main debugging in a Mac OS X/Darwin version of your program.
There are three major Pascal dialects: Turbo Pascal (extended to Delphi, supported by FreePascal, and partially by Gnu Pascal), Extended Pascal (an ISO standard, supported by Gnu Pascal, DEC Pascal, Prospero Pascal), and the dialect originating from Apple (commonly used in the Mac community, supported by MPW Pascal, Metrowerks Pascal and Think Pascal). We call this dialect Mac Pascal and there is a special language mode for it: MacPas.
Mode MacPas is a compatibility mode. It is probably not possible to mimic the Mac Pascal dialect in detail. So the goal is to implement often used constructs, if this doesn't require too much effort, as well as easy-to-implement constructs.
To use MacPas, add -Mmacpas to the command line or insert the compiler directive {$MODE MACPAS} in the source code.
Note that the mac pascal dialect and mac targets are not interrelated. It is thus possible to write a mac program with the turbo dialect and to write a Windows program with the mac dialect.
The following are supported: Mac compiler directives like $SETC, $IFC, $ELSEC, $ENDC, $J, $Z. Most of the constructs found in interface files, especially Apples Universal Interfaces. Cycle, Leave, Otherwise. More is planned.

There is a rich tradition of operating systems written in Pascal. The probably best-known example is classical Mac OS, a very influential historic operating system, that was nearly entirely written in Pascal (not to be confused with macOS that is written in Objective C). Other operating systems written in Pascal include Lisa OS and the Lillith system software. The operating system for the famous Xerox Star was written in the Mesa programming language, a modular language of the Pascal family. Today there are several attempts to write a Pascal-based operating system from scratch. The following, probably incomplete, list contains some approaches to use Free Pascal for creating an OS.
fpos
An Operating System written from scratch with Free Pascal compiler.Interested in developing an OS with Free Pascal? This project can be used as a starting point (though incomplete and YOU ARE WELCOME to complete it :-)).
StreamOS
StreamOS is 32-bit operating system written in Object Pascal using Free Pascal Compiler. It’s designed for:
- scientific tasks such as long calculations;
- finding the best architecture of mixed kernel;
- academic interests.
The main advantages are:
- 32-bit fast kernel;
- no global kernel locks;
- full parallel threading model;
- easy API;
- integrated Virtual Filesystem support called StreamFS;
- Unix-likeness.
TORO Kernel
Toro is a kernel created in Pascal using FreePascal compiler. The project was started in the year 2003 by Matias E. Vara using a monolithic kernel.The whole kernel is included in a RTL compliant with FreePascal for i386 and AMD x86-64 processors. The user program is compiled within the kernel and is executed in kernel mode. The intrinsic OS design select strict model in data workflow and pipeline of execution in order to avoid concurrent execution on the same shared memory region. The kernel was optimized for Multicore system and that is the principal objective of the project ,fix the current problems of Modern O.S. in Multicore environment. The main features are:
- Supports Multithreading with SMP(Symmetric MultiProcessing).
- Simple interface with Lazarus IDE for programmers.
- Supports AMD x86-64 and Intel EMT64 architecture.
- Designed to optimize the use of AMD HyperTransport technology and Intel Quick Path Interconnect technology.
- NUMA Memory Model (Non Uniform Memory Access).
- Stack TCP-IP.
- Virtual Filesystem.
- Independent of architecture.
FP-RTOS
A realtime kernel for embedded development. Primarily developed for ARM devices. Written entirely in Pascal and inline assembler.
- Preemptive multitasking
- Synchronization primitives(Mutex, Critical section, spinlock, and signals)
- Threadsafe queue and delays
- Optional safety features: Deadlock detection, priority inheritance, etc
Ultibo core
Ultibo core is a kernel in an RTL first released in 2016, much more than just another OS example it is a complete platform for creating modern full featured embedded applications which run without any operating system. Written 100% in Free Pascal and initially targeting Raspberry Pi, the modular design allows including only the features required for any given project. Packaged in a simple installer download for Windows or as an install script for Linux customized versions of both Free Pascal and Lazarus IDE are included along with full source and a collection of examples to get started quickly.
Features include:
- Support for all models of Raspberry Pi (A/B/A+/B+/2B/3B/3B+/Zero/ZeroW) plus QEMU ARM emulation
