I got my Macbook Pro 15" around 2011 to edit videos for my film school. I carried my MacBook around with me using Final Cut Pro 7 with no problem for around 2 years. I stopped editing videos after I graduated, but time to time I tried using Final Cut Pro again, but it won't let me edit without a huge lag. (I always use an external HD when editing videos) I can't even play the preview especially when I have some effects on it. I also tried using Premiere but my mac just half-freezes. Is it because my Macbook is too old and the processing speed is too slow? I'm not trying to make a 2hrs long feature film, it's more like a short film. This MacBook still works great with other software, so I wish I can find a way to edit videos again with this MacBook.
P.S. I didn't update my OS yet. Should I??
