I am pretty much a beginner with editing and new to the apple communtiy. Im looking to purchase a PORTABLE mac to use fce 4 and eventually fcp studio 2. I have a hp now and use sony vegas but i experience dropped frames and skipping/glitching in my final product. Ive tried tons of crap to fix it and nothing works. Purchasing my new set up i want to make sure i get what i need to avoid this at all costs. For editing how much better is the macbook pro vs the macbook? What should i get?? set up recommendations?
