GNU Fortran

I provide GNU Fortran packages for macOS (for more details, see these explanations):

• gfortran 14.2 for macOS Sequoia (macOS 15), Intel and ARM processors
• gfortran 14.2 for macOS Sonoma (macOS 14), Intel and ARM processors
• gfortran 12.2 for macOS Ventura (macOS 13), Intel and ARM processors
• gfortran 12.1 for macOS Monterey (macOS 12), Intel and ARM processors
• gfortran 11.3 for macOS Monterey (macOS 12), Intel and ARM processors
• experimental gfortran 11 for Apple Silicon (macOS Big Sur 11 with ARM processors)
• gfortran 11.2 for Big Sur (macOS 11) on Intel processors
• gfortran 10.2 for Catalina (macOS 10.15)
• … and previous versions here

Another installation method is to use the Homebrew package manager, to install GCC and a lot more open source software. I am a maintainer of Homebrew, and of the GCC compiler (in particular, its Fortran front-end, gfortran).
