+##### On macOS
+
+Watch out! For weird reasons, the LibreOffice command line binary has a non-obvious name on macOS:
+`soffice`, probably because until 2010 the software was named StarOffice.
+Install the necessary Java Development Kit (which is needed for LibreOffice to run) and LibreOffice
+itself for example with the packet manager [brew](https://brew.sh):
+
+```
+brew install openjdk
+brew install libreoffice
+```
+Check if LibreOffice is installed correctly:
+
+```
+soffice -v
+# should show
+# LibreOffice 7.0.x.x
+```
+And in your code tell the Converter the name of the binary:
+
+```
+$converter = new Converter('soffice');
+```
+
