I'm curious as to how both the newer rMB's and the 2015's handle VMs. Has anyone tried them? If so, please let me know how they perform If you'd like to try them out but have none installed, install VirtualBox (available here: https://www.virtualbox.org/wiki/Downloads) and download the latest Ubuntu (available here: http://www.ubuntu.com/download). If you don't have experience with VMs, let me know and I will try to assist you through it. I'm mainly asking because I needed to use a VM last semester (VirtualBox with Ubuntu 14.04) in my software engineering class, but my 2012 non-Retina MacBook Pro had trouble at times running it (probably due to 4GB of RAM more than anything), but I want to replace this computer for many more reasons than just that. I don't plan on using VMs for any Windows OS (I was planning on using Boot Camp for those), but any insight into how it runs those is welcomed as well. Thanks!
