I'm a research student working on text mining areas. I normally use Macbook Air 2013 (13 inches, 1.7 GHz Intel Core i7, 8 GB RAM, 256GB) to process heavy tasks of text processing. Sometimes I find that my machine runs load of things and I hear noise (kinda fan noise but not sure if it has a fan) from it. When it runs, there is no sign of the slowness of the macOS. But I think that I need more space due to the work. Thus, I'm thinking of to get a new Macbook Pro but hesitating about its limited ports and CPU performances. Is there anyone here working on Text Mining area? How long have you used your machine. Thank you.
