Hi all - I have a few questions. I'm currently using a 2014 MBA, 8GB of RAM and 1,4GHz i5 processor. I've thought about loading Windows on my Mac before - mainly for the occasional Excel graph that's not included in Excel for Mac or some other program. Now, I know I have three options: virtual machine, parallels or bootcamp. Considering my specs, the fact that I have a 256gb SSD what option would you suggest between the three? For virtual machines I have VirtualBox installed already. My usage will be mainly for Excel and some other occasional program. Another question is security: will I need an antivirus or other specific programs?
