This is a quick demo of J. River MC 16 on my Macbook Pro via Parallels Desktop 6.
This was done on a basically stock Macbook Pro 15. It has a 2.0GHz Core i7 CPU (Sandy Bridge), 4GB of RAM, and the AMD Radeon HD 6490M GPU. I configured Parallels to use 1.5GB of RAM and "2 cores" (of the "8 cores" available on the Core i7 with Hyperthreading). The Macbook does have the high-resolution screen option, and a 750GB hard drive (the slower one though).
