Hey guys, I have a 15inch base 2013 rMBP with parallel mainly for excel use. I use excel intensively for my work and there is no way around it. I am annoyed with how poorly excel on parallel runs on the macbook. I think the performance has to do with scaling. I was hoping if anyone have insight regarding this. Or, if anyone has other suggestion on running windows excel on Mac with large data sets, please let me know. If there is no way around it, I guess I need to go back to windows. Thanks!
