i have just discovered Gunbot and am currently reading more about it, but it looks very interesting.

i use a Mac day to day, but also have an old Windows (Windows 7 i think) laptop that i could also use.
Is there any difference in versions and is using the Mac version hard on the CPU?

Do most people use the AWS vpn? is this the recommended option?

Are there licences available? If i get a licence, can i use it both on my Mac and Windows laptop? (one at a time)

there is a lot of pages and the forum to read through, which i haven't finished yet, so apologies if these are very newb questions
