Yes, to the question in bolt type...Parallels, VirtualBox, VMware...but before you do, it's best to maxed out your RAM. Then, you could have Windows 7, 8, and 10 virtual machines. BTW, I have both Parallels and VirtualBox with Ubuntu, Fedora, Windows XP, Windows 7 Ultimate, Windows 10, Solaris, CentOS, SUSE, FreeBSD, and pfSense all on a 2008 Macbook Pro 17" all running great except memory hungry Windows 10 which runs slow on 6GB RAM laptop.I *really* dislike windows 8 & windows 10. Is there a workaround for installing windows 7 on El Capitan? The machine is a mid 2015 RMBP.
Like member BrianBaughn stated about the limitation of El Capitan, the same goes for Sierra. The limitation has to do with the hardware. A Mid 2015 rMBP can only run Win 8 or 10 without a work around.I run windows 7 on a Mac mini that has sierra on it so you should be able to do it with El Capitan. I found a couple of websites that show how to do it.
