The CPU usage is very high, sometimes peaks at 50%, which makes working on Mac challenging while the real-time antivirus enabled. The app only detects 90.6% of Mac malware, which is below the industry average. Overall, the McAfee Total Protection is not good for Mac. Unfortunately, the results were somewhat unexpected and underwhelming. I reviewed a dozen antiviruses for Mac in the past year, and since McAfee is a well-known brand in the cybersecurity space, I spent an entire week testing its flagship product for macOS.
