Is your Mac up to date with the latest version of the Mac operating system (macOS or OS X)? Is it using the version required by some product or feature? Which versions are earlier (older) or later (newer, more recent) than the version currently installed? To find out, learn which version is installed now.

If your macOS isn't up to date, you may be able to update to a later version.

Which macOS version is installed?

From the Apple menu  in the corner of your screen, choose About This Mac. You'll see the macOS name, such as macOS Mojave, followed by its version number. If some product or feature requires you to know the build number as well, click the version number to see it.

This example shows macOS Catalina version 10.15 build 19A583.

Which macOS version is the latest?

These are all Mac operating systems, starting with the most recent. When a major new macOS is released, it gets a new name, such as macOS Catalina. And as updates that change the macOS version number become available, this article is updated to show the latest version of that macOS.

If your Mac is using an earlier version of any Mac operating system, you should install the latest Apple software updates, which can include important security updates and updates for the apps installed by macOS, such as Safari, Books, Messages, Mail, Music, Calendar, and Photos.

First let me say I’m not a big Fortran user but any blog posts about Fortran always seem to be very popular, and I do get asked regularly about how to compile Fortran applications.

If you have followed the instructions on Cheminformatics on a Mac you already have Xcode, Command Line tools and gfortran installed using Homebrew. Alternatively you can install GCC 8.3 (auto-vectorizing gcc with OpenMP) which includes gfortran (free, open source, GNU Fortran 95 compiler), gcc (GNU C) and g++ (GNU C++) compilers that can perform auto-vectorization (i.e. modify code to take advantage of AltiVec/SSE, automatically) and other sophisticated optimizations like OpenMP. There are detailed instructions here, last updated April 2019 (Mojave).

Portland group also has a commercial fortran compiler as part of their offerings (PGI). Details of compatibility with the latest versions of mac OSX are available here.

The newest update to PGI Fortran, C and C++ compilers & tools for scientists and engineers. Includes Volta support, using CUDA Unified Memory with OpenACC, Open 4.5 CPU support, C++14 lambda and capture support within OpenACC and…. On Intel Haswell CPUs with OpenMP, PGI delivers multicore performance more than 50% faster than the latest GCC compilers. That’s like buying a cluster with 50% more compute nodes. PGI compilers deliver world-class multicore CPU performance and accelerator programming features that can dramatically increase the performance of applications on GPU accelerators. New features include V100 Tensor Core support, full C++17 language support, OpenACC printf(), PCAST directives, LLVM 7.0, Turing support.

There is also a free version of the PGI compiler released April 30, 2019

Pro Fortran for macOS System Requirements

• Intel CPU based system – multi-core suggested for best performance
• macOS Sierra (10.12) through macOS Mojave (10.14)
• OS X Snow Leopard (10.6) through OS X El Capitan (10.11)
• 2 GB RAM – 4 GB recommended for best performance
• 1 GB free disk space for complete installation

Arguably the best fortran compiler for Intel macs are the Intel compilers ifort.

The Intel® Fortran Compiler builds high-performance applications by generating optimized code for Intel® Xeon® Scalable processors and Intel® Core™ processors. Its features allow you to: Boost Single Instruction Multiple Data (SIMD) vectorization and threading capabilities (including for Intel® Advanced Vector Extensions 512 instructions) using the latest OpenMP* parallel programming modelTake advantage of more cores and increased vector register width available in Intel® Xeon® processorsComply with open standards such as Fortran and OpenMPWork with a familiar set of tools on your preferred platform: Windows, Linux, or macOS*

They can build pretty much any fortran code including very old fortran (as far back as fortran 66) and support the latest fortran standards. And in many people’s experience produce the fastest runtime executables. They also integrate directly into Xcode and tend to be the most up to date in terms of compatibility with the apple dev tools. They are also link compatible with both gcc and clang. ifort also includes a fortran version of their MLK library.

They provide redistribute libraries for dynamically linked binaries, but they also support static linking, so in either case binaries can be distributed to people without the compiler installed.They aren't free on Mac (they are free on Linux), but the academic price is relatively inexpensive. Additionally they have a C/C++ compiler suite, but the performance gain over clang is no longer there. They are better than gcc in terms of codgen, however. So if you aren't using MLK there may be no benefit.

NAG Fortran Compiler.

The NAG Fortran Compiler is robust, highly tested, and valued by developers all over the globe for its checking capabilities and detailed error reporting. The NAG Fortran Compiler is available on Linux, Microsoft Windows and Mac OS X. The latest release (6.2) has extensive support for both modern and legacy Fortran features, and also supports parallel programming with OpenMP.

Given the move towards parallel processing it is useful to note that most of the compilers support OpenMP, OpenMP is a specification for a set of compiler directives, library routines, and environment variables that can be used to specify high-level parallelism in Fortran and C/C++ programs.

Critic2: A program for real-space analysis of quantum chemical interactions in solids DOI

Download critic2 from: http://gatsby.ucmerced.edu/downloads/critic2/critic2-1.0.tar.gz

Once downloaded:

This compiles and installs:
- critic2, basin2off, off2off, charges.sh executables to /usr/local/bin
- data files to /usr/local/share/critic2
- help files to /usr/local/share/doc/critic2

A couple of Fortran experts have contacted me and suggested I include these flags that are often very useful for developers.

-static-libgcc : includes all necessary system routines in the binary and thus avoids error messages at runtime when some library is missing on the user computer

-mmacosx-version-min=10.1 : generates binaries able to work under several os x versions

-fno-underscoring : supresses the trailing undersore for names of functions and subroutines (but then you must take care about conflicting names)

f90wrap is a tool to automatically generate Python extension modules which interface to Fortran libraries that makes use of derived types. It builds on the capabilities of the popular f2py utility by generating a simpler Fortran 90 interface to the original Fortran code which is then suitable for wrapping with f2py, together with a higher-level Pythonic wrapper that makes the existance of an additional layer transparent to the final user. f90wrap has been used to wrap a number of large software packages of relevance to the condensed matter physics community, including the QUIP molecular dynamics code and the CASTEP density functional theory code.
