Thanks to yours previous support I've released Portable LibreOffice OS X. http://www.freesmug.org/portableapps:libreoffice It open LibreOffice with a shell script using -env:UserInstallation=file:///... wrapped in a application bundle. Just a little issue when first time I type some text JREproperties write a "Portable" file in the same folder of Portable LibreOffice.app with this content: <?xml version="1.0" encoding="UTF-8"?> <!--This is a generated file.
