 <typo fs:xx-large; fw:bold>MacOS</typo>
+=== Homebrew ===
+[[https://brew.sh]]
- [[https://github.com/AdoptOpenJDK/homebrew-openjdk]] where you can go and grab prebuilt openjdk binaries for macOS! \\
+====== Development on MacOS ======
+===== C/C++ =====
+Using ''Homebrew'':
+<code>
+export HOMEBREW_NO_ANALYTICS=1
+brew update
+brew upgrade
+brew info gcc
+brew install gcc
+brew cleanup
+</code>
+Alternative: go to the Apple App Store and install ''Xcode'' //(Apple's compiler and development tools)//. \\
+Then, in a terminal:
+<code>xcode-select --install</code>
+<code>clang -o program program.c</code>
+<code>clang++ -o program program.cc</code>
+<code>g++ -std=c++11 -o program program.cpp
+g++-7 -std=c++11 -o program program.cpp</code>
+<code>
+brew install pkg-config
+brew install gettext
+brew install glib
+export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/X11/lib/pkgconfig
+</code>
+<code>
+==> Caveats
+==> libffi
+libffi is keg-only, which means it was not symlinked into /usr/local,
+because some formulae require a newer version of libffi.
+For compilers to find libffi you may need to set:
+  export LDFLAGS="-L/usr/local/opt/libffi/lib"
+For pkg-config to find libffi you may need to set:
+  export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
+</code>
+=== Portable alternative for getting current time ===
+<code>
+#include <time.h>
+#include <sys/time.h>
+#ifdef __MACH__
+#include <mach/clock.h>
+#include <mach/mach.h>
+#endif
+struct timespec ts;
+#ifdef __MACH__ // OS X does not have clock_gettime, use clock_get_time
+clock_serv_t cclock;
+mach_timespec_t mts;
+host_get_clock_service(mach_host_self(), CALENDAR_CLOCK, &cclock);
+clock_get_time(cclock, &mts);
+mach_port_deallocate(mach_task_self(), cclock);
+ts.tv_sec = mts.tv_sec;
+ts.tv_nsec = mts.tv_nsec;
+#else
+clock_gettime(CLOCK_REALTIME, &ts);
+#endif
+</code>
+===== Java =====
+See [[https://github.com/AdoptOpenJDK/homebrew-openjdk]] where you can go and grab prebuilt openjdk binaries for macOS! \\
