What Intego Mac Internet Security X9 is
Intego Mac Internet Security X9 is paid macOS security software that combines VirusBarrier X9 and NetBarrier X9. VirusBarrier provides real-time protection, scans files when accessed, supports on-demand scans, and is described as covering Mac and PC malware. NetBarrier blocks unsolicited visitors and provides firewall protection for home and hotspot networks. It can switch firewall settings automatically based on whether the Mac is at work, traveling, or in a cafe. Intego lists support from macOS High Sierra 10.13 through macOS Sequoia 15. Installation requires a compatible officially supported Mac or PC, 1.5 GB of free disk space, and an active internet connection; general requirements list macOS 10.13 or later and Windows 7 or later. The product covers one Mac. Intego says Mac Internet Security X9 is a legacy product no longer available as a separate new purchase.
