I WANT TO KNOW IF THERE IS ANY YOU TUBE APP THAT WOULD MAKE IT EASY TO BROADCAST A LIVE STREAM, BOTH AUDIO AND LIVE VIDEO FROM A MACBOOK PRO RUNNING MAC OS X YOSEMITE 10.10.5. THANK YOU. I AM TRYING TO HELP MY GRANDSON SET UP HIS FIRST PERSONAL BLOG. HE DOES IT NOW FROM HIS IPAD, BUT I THOUGHT IT MUST BE EASIER USING MY MACBOOK PRO. AGAIN, THANKS
