I found this tutorial at the adafruit's website which lead me to the following article ( http://4dc5.com/2012/06/12/setting-up-vnc-on-raspberry-pi-for-mac-access/ )
About how to connect your RPi to your network the OSX "friendly way" a.k.a. have it's drive at the Finder's sidebar and simply shared screen
I just wanted to turn of the screen blanking on my Raspberry Pi running Jessy, so I googled after it found this solution which worked for me:
"
sudo nano /etc/lightdm/lightdm.conf
In that file, look for:
[SeatDefault]
and insert this line:
xserver-command=X -s 0 dpms
"
But a lot of people complained it did not work for them so in the case it would not work it might worth to try this too
"
sudo nano /etc/kbd/config
edit these values to:
BLANK_TIME=0
POWERDOWN_TIME=0
"
