| 15 | + |  **Warning **| In Lazarus 2.2.0/FPC 3.2.2 and later, the target for building iOS applications was changed from Darwin to iOS due to the advent of the Apple Silicon M1 (ARM64) processor in Mac computers. | |

| 5 | 19 | ## Introduction | |
| 6 | 20 | ||
| 7 | - | ||
| 21 | + | Darwin is the target for macOS and iOS, both PowerPC, ARM and ARM64, i386 and X86_64. Programs may also be run on a machine with only Darwin installed. | |

| 9 | 23 | ## Installation | |
| 10 | 24 | ||
| 11 | - | ||
| 25 | + | See [[Installing Lazarus on macOS]]. | |

| 16 | 30 | ||
| 17 | - | ||
| 31 | + | Lazarus is a Delphi-style RAD environment | |

| 35 | + | A free IDE in the classic Mac style | |
| 22 | 36 | ||
| 23 | - | ||
| 37 | + | 3) Any Editor (AlphaX, BBedit, ...) and command line (fpc your_pascal_program.pas) | |

| 25 | 39 | ## Universal binaries | |
| 26 | 40 | ||
| 27 | - | ||
| 41 | + | Normally for each processor - operating system combination there is one executable, but in macOS you can combine an aarch64 (ARM64) binary and an x86_64 binary into a so-called "universal binary" or "multi-architecture binary" that will run on both Apple ARM64 processors and Intel 64 bit processors. To do this the ARM64 and x86_64 executables have to be compiled separately and then combined using the `lipo` command line utility. | |
| 28 | 42 | ||
| 29 | - | ||
| 43 | + | It is also possible to combine a PowerPC binaries and an x86 binaries into a single combined binary using the `lipo` command line tool. You would need to first [download the PowerPC cross-compiler](<https://sourceforge.net/projects/freepascal/files/Mac%20OS%20X/>) so you only need to use `ppcppc` instead of `fpc` to build your project to generate the PowerPC binary. If you have a PowerPC computer, then the simplest solution is to build the x86 binary on a different computer with x86 architecture. | |
