I am in the same situation as Serendigity. I can run the current version OK (and I have played with all the various functions and features, loaded additional star charts, landscapes and nebulae), but do get the brief artifacted/pixellated screen just before the startup logo. I have an early 2009 MacBook Pro unibody, 2.8 ghz/4 GB RAM, running NVIDIA GeForce 9400M graphics. I am using 1440x900 resolution.
I do have to say that this version does seem to be a CPU hog though, if I do much in it (other than having the basic sky view while letting normal time run), it makes my laptop hot and the fans come on frequently.
