Hello I migrated from PC to MAC. Got my sell macbook pro late 2011 - i7,4gig ram,HD 5400rpm (OS X Lion 10.7.5) and RME Babyface latest drivers. Unfortunately I have a huge problem with my DAW's. I'm running Live 8 ,Cubase 6.5.3 and Logic 9 that my friend gave me to see how it will behave. No matter what program I use I get the same picture. Audio channels 2-5, 2-4 VST instruments. I also use very little EQ and Compression.Two send fxs reverb,delay. At this point the computer temperature reaches 90 degrees and fans spin around 7000 rpm.CPU meter on all DAW's show almost 90% and well only cubase clicks but all of them run very hot. I also imported few projects from cubase that are on core2duo that few years old.The cpu meter show me around 40% and it was full 100% on mac. Activity monitor show me that I used around 280% cpu on both examples. I decided to do simple test just on all DAW's. Loaded 10 channels with the same loop and same plugin(Aether). CPU on DAW's 50-55% and in activity monitor 240-250%. So at these point I think its not cubase problem but my OS/Hardware. BTW I run all the projects/test true rme and build in core audio without any difference. Buffer settings didn't effect the performance at all. Did disk repair permissions. I know my HD is very slow....but I was doing orchestral and electronic production on my old pc that maybe have 1/4 of this mac power with 2gig rams. I don't know what to do I spend so much money on mac,rme,arturia midi controller so I just could work. Please send me some advice.
