Sophos installed in a flash on the MacBook Air I use for testing. The Premium edition lets you manage 10 devices, and it adds useful security-related features, too. If you need more than three and don't want to set up another free account on a separate email, you must upgrade to Sophos Home Premium (for Mac). From the online console you can install and manage protection on three devices, whether they run macOS or Windows. To get started with Sophos, you register an account online. It's no surprise that the consumer edition works the same way. Sophos is a big name in the enterprise-level antivirus world, where a central IT administrator controls all the local installations. If you're willing to protect your Macs with antivirus but don't want to splash any cash, consider Sophos Home Free (for Mac), especially if you need to manage protection for others. But Macs need protection too, from ransomware in particular. You'd be loony to go without antivirus protection on your Windows boxes. True, Windows is more popular with malware coders around the world, because it offers more of an attack surface. PCs get viruses, Macs don't, right? Wrong.
