So, i've been having a lot of trouble with overload issues on my 2007 MacBook Pro. It's really got me confused because the problem seemed to just start occurring recently on fairly simple projects. My macbook has 2.2 core duo processors, 4gb rams, ~60 gigs of free HD space, and I'm running projects from an external drive. I am aware of the tricks for optimizing projects (balancing processor thread loads and whatnot) so please don't point me to that section of Logic's manual. I just have no idea what the problem is, especially since I used to run fairly large projects in the past with very little free HD space and somehow got away with it.
