I'm gonna edit a 30-40 min film on my MacBook (2.0GHz Aluminum Unibody, Late 2008) for our school's "Film Fest" on Final Cut Pro X. I'm upgrading its RAM to its maximum capacity 8GB. Can my Mac take it? I currently have 2GB of RAM any I tried to create a 3-5 min video and I got problems saving it, so I'm really worrying.
