100% agree with you mate! & to be judged saying you have an out dated mind set
I have installed Lion,Mountain Lion & Mavericks giving them a try i kept & went back to Snow Leopard 10.6.8 which for me is the best! i just want to make music!
Mavericks Logic 9.1.7 or 9.1.8 Logic EQ mouse scrolling is sticky & laggy with a problem like that there will be other problems in Mavericks also with Lion,Mountain Lion & Mavericks the quicklook was not as fast as Snow Leopard when going through my wav samples or just music,it feels as new OSX comes out things are becoming more difficult.
I wonder who is going to say you "you should not be using Logic 9 on Mavericks" Haha! There is no question Apple do all this for money & makes me laugh when i see "but its free".
