I'm running the Trial Version of ESET "Smart Security Premium" on my HP computer using Windows 7. I have another computer using Windows 7 also which I'll be putting ESET on. I also have a iMac computer running macOS Mojave. I want to put ESET on my Mac also when I upgrade to macOS Catalina when it is released soon. My question is when I buy my license at the end of the trial, do I buy "Smart Security Premium" to install on all three computers (two Win 7's and one Mac) or do I have to buy a separate license for the Mac? I want to make sure I buy the right license when the time comes after the trial.
