The laptop I have is a Macbook 4.1 with 2.4 GHz Intel C2D with 4 GB of 667 MHz RAM. I am about to upgrade from Leopard to Snow Leopard this week. Also, I will be using a 1 TB external HDD to run media from and use as a scratch disk. Will AE CS5.5 run on this set-up decently enough where it wont crash? I understand renders will be tediously long and excruciating, but this Macbook is all I have to practice with because 43 hour work weeks disallows me for time to head to school and use the iMacs there for learning CS5.5 ... 🙁 Need to practice at home.
