So my Macbook Pro early 2011 13" tends to always run into problems when I use Amadeus Pro and as a result the entire system becomes unbearable. Here's what I've been able to gather: The CPU usage never really gets above using 40% so I doubt there are problems there. I've upgraded the RAM to OWC's 8GB and it's helped, but it's still crushing the system. Right now I have 21MB free with 1.33GB wired, 4.44 GB active and 2.18GB inactive. I know Amadeus Pro, when it does run tends to take 1 GB of ram (due to the large files I have to process). I'm wondering what's going on and why OSX (10.7.4) hasn't already aggressively freed the inactive RAM considering there's a very noticeable hit in performance and what I should do. Thanks!
