Hi. I was given a 2013 Macbook Pro Retina 13", 2.4GHz, 8GB, w/ SSD running on Mavericks (my first mac). It currently has VMware Fusion 4 with Windows XP (not sure why XP over W7). I would like to upgrade it to newer versions of those software. The computer would be used for basic productivity work (no gaming but will include light video editing). My questions are the following: Would it not be advisable to run VMware 10 and Windows 10 because of the age of the system? Would it be better to run Fusion 8.0/8.5 and Windows 7/8 for the sake of speed and efficiency? Are the latest copies of Fusion and Windows sold as a bundle for a discount? Would Parallels be better for an older MBP? If so, which versions should I consider? I'd appreciate any feedback. Thank you very much.
