+###Use default options.
+###Add to the PATH environment variable with this temporary solution.
+export PATH=/users/$USER/Qt/5.5/clang_64/bin:$PATH
+###Depends on wich version of Qt you use.
+
+##################################
+###--- MACPORT INSTALLATION ---###
+##################################
+
+###Install MacPort and XCode following this guide:
+http://guide.macports.org/#installing.xcode
+
+###Start XCode to get it updated and to able C compiler to create executables.
+
+###Install libraries
+$sudo port -v selfupdate
+$sudo port install openssl
+$sudo port install miniupnpc
+
+###Get Your OSX SDK if missing:
+https://github.com/phracker/MacOSX-SDKs
+
+###########################
+###--- LAST SETTINGS ---###
+###########################
+
+###In QtCreator Option Git add its path:
+C:\Program Files\Git\bin
+### and select "Pull" with "Rebase"
+
+###Compil missing libraries
+###SQLCipher
+cd <your development directory>
+git clone https://github.com/sqlcipher/sqlcipher.git
+cd sqlcipher
+./configure --enable-tempstore=yes CFLAGS="-DSQLITE_HAS_CODEC" LDFLAGS="-lcrypto"
+make 
+sudo make install
+#NOTE, might be necessary to chmod 000 /usr/local/ssl temporarily during ./configure if 
+#homebrew uses newer, non-stock ssl dependencies found there. configure might get confused.
+
+### libMicroHTTPD: The one with port don't have good support.
+cd <your development directory>
+wget http://ftpmirror.gnu.org/libmicrohttpd/libmicrohttpd-0.9.46.tar.gz
+tar zxvf libmicrohttpd-0.9.46.tar.gz
+cd libmicrohttpd-0.9.46
+bash ./configure
+sudo make install
+
+###You can now compile RS into Qt Creator or with terminal
+cd <your development directory>
+git clone https://github.com/RetroShare/RetroShare.git retroshare
+cd retroshare
+qmake;make
+
+###You can find compiled application on ./retroshare/retroshare-gui/src/RetroShare06.app
