You can use it on any system.
Not at the same time, but you can activate it on you PC and a Laptop for example. Just make sure not to use both instances at the same time. So if you want to use it on Mac, you should close it on the PC first.
It is very refreshing to have a software organization whom very plainly offers a strong product, supports it well, does not overcharge or over frequently charge and essentially just wants to put a smile on the face of their customer. Contrast this with most other software companies (particularly the large ones) whom at hearing the very simple mention of interest in their product all but kicks in your door, punches you in the face and steals your wallet to never be heard from again.
I wouldn't word it that hard. RF is not the only good software company/developer. There are great programs out there. But not all of them have lifetime licenses (only a yearly subscription) and some don't care about what the customers say. I use(d) a screenshot program and asked the dev something, I think twice. Never got any response.
I did not say nor infer they were the only good one. This is why I used the word "most". This is from my personal point of view as someone whom has worked in tech for multiple decades. Anyway, none of that was the point of my post.
