Hi, This is my first time using ANY forum. Apologies in advance! I currently have a mid 2010 MBP - 13", 2.4 GHz intel C2D + 4GB 1067 MHz DDR3. I use my MBP mostly for internet, iPhoto, some iMovie but mostly I use my MBP for making music. I use Logic exp 9, I have a few independant plug-ins etc and I have also recently installed BFD2 which I've heard is not very CPU friendly. So my problem is - Ive recently updated my osx to mavericks and everything is running too slow. My tascam Audio interface no longer works, which I've accepted and buying new model. After reading a bunch of other forum threads I've realised i probably shouldn't have updated to mavericks but I have and can't go back so working out how to go forward. My CPU usage seems to be the problem and keep getting warnings "couldn't process audio..." etc... I need some advice on how to help my MBP run smoother/faster. Would upgrading RAM help? Any feedback would be much appreciated!
