Reply to does anybody know what david guetta is using?

production wise I know that once you get enough coin the sky is the limit on how much gear you can buy, but i recently saw a behind the scenes on tv for a video shoot of his and i missed it when he said what he was using for production he said hi mac book and something else, I was in shock and couldnt remember.
how a world class dj/producer made super huge tracks just using his laptop a midi and i cant recall what software
IF THERE IS ANYONE WITH THIS INFO OR WITH A GENERAL IDEA OF WHAT he is using or what major record label producers are using i would appreciate it and also sticker price.
