Usually, it is the application performing the Illegal Operation. However if you were to install Safari on your windows PC, you would be performing the Illegal Operation. According the Safari License Agreement (below) you are allowed to, “…install one copy of the Apple Software on a single Apple-labeled computer…”
I know many consumers never bother to read the End User License Agreement (EULA) when they install software, but apparently Apple hasn’t bothered to read their own EULA for Safari. Looks like they are recycling the old EULA from when Safari was Mac only application when they pushed it out to Windows last year. Either that, it is a trick by Apple to get everyone to switch over to Macs or risk being sued. That would be an interesting Get A Mac campaign.
