macbook pro 2015 to mixer

Hi Guys ,

I'm using a MacBook Pro 2015

I would need some of your help as i have to do some video project that i have to present it in one of our Church Events and i never done this before. I have absolutely no ideas with this.

I have some video that i made on my MacBook Pro 2015 and i have to connect it to mixer and it will go to Projector for all of the audience to see.

What type of extra cable that i should have ?

or HDMI only will do ? Because i have a HDMI Cable

Thanks a lot
