Intego

For Macs, yes — that's its entire specialty. Intego builds security only for Apple systems, and it shows: strong macOS malware detection in independent tests, plus genuinely Mac-native tools — the NetBarrier firewall, backup and parental controls — that feel like macOS software rather than a Windows port. The focus is also the limitation: there's no real Windows protection, so mixed households need a cross-platform suite like Bitdefender or Norton instead. If the machines you care about are Macs and you want dedicated protection beyond what macOS ships with, Intego is the strongest Mac-specialist pick in our lineup.

The plan we track is Intego ONE Essential for a single Mac: US$29.99/yr for the first year, renewing at US$39.99/yr. Covering more Macs, or stepping up to the fuller bundles that add the NetBarrier firewall, backup and parental controls, raises the price from there. As with most antivirus brands, the first-year rate is promotional — check the renewal line item as well as the current offer on Intego's site before you buy. There's no free version, only a trial, so plan on paying from year one.

Intego is legitimate, Mac-only security software — antivirus, the NetBarrier firewall and backup tools. If it's on your Mac, it got there one of two ways: you installed it, or it was bundled with something else you bought. It isn't malware, and it isn't part of macOS itself. If you have an active subscription, keep it — it's what's doing the protecting. If you don't use it, remove it with Intego's own uninstaller rather than dragging it to the Trash, so its background components are fully cleaned out.

Generally no. Intego is written natively for macOS rather than ported from Windows, and in everyday use — browsing, mail, office work — it stays light enough not to notice. The exception is a full system scan, which can slow older Macs while it runs; schedule scans for idle times (overnight, lunch) and you'll rarely feel them. If a Mac is sluggish all the time, the cause is usually elsewhere — full storage, low memory or another heavyweight app — not Intego's background protection.

Install and open the Intego app, then go to the account or serial-number section and enter the activation code from your purchase-confirmation email — or sign in with your Intego account, which links your license. One bundle code activates every app included in your bundle, so you don't repeat the process per tool. Afterwards, run an update so the malware definitions are current, then a first full scan. If a code is rejected, check for typos and confirm in your Intego account that the subscription is active.
