Windows only I'm afraid. I know several people who use parallels and install RoboHelp there.
Can someone suggest parallel ways to install RoboHelp 2015 on Mac OS?
I believe "Parallels" is a software application that you install on a Mac that allows you to then install Windows. You may want to find a Mac forum or do some google searching for "Parallels" and perhaps you will find more information there.
As I understand it, Parallels installs as an application inside the Mac operating system. From there, you open a window that runs the Windows operating system so you can install and operate Windows applications such as RoboHelp.
Another alternative is something called "Boot Camp". With Boot Camp, you choose at the time you are booting up your computer which operating system you want to use. From that point forward you are either in Windows or the Mac operating system entirely.
VMWare Fusion is another solution. Works much the same way as Parallels...it allows you to run a Windows VM inside your Mac. The advantage of BootCamp, however, is that you boot either completely into Mac or Windows...and if you're running a resource-intensive app on the Windows side, then BootCamp may be a better option. It all depends on your usage scenario
