I just purchased a refurbished 2013 MacBook Air. It's my first Mac and I'm really excited. I'm trying to move over about 300gb of music/movies from my PC. I started last night , but when I woke up this morning I think the migration totally overloaded my internet connection and I had to reset my wifi and start over. Are there any alternatives to transferring all of this data? It was also approximating about a 50 hour transfer. Is that standard for that much data?
