CST VerdictBased on our analysis of available product data, here is our conclusion:
Mac-only security teams with sparse IT budgets should pick Do Not Disturb for its single, well-executed function: catching when someone physically tampers with an unattended laptop. The tool detects unauthorized access attempts through simple file system monitoring, costs nothing, and has been validated by 312 GitHub stars from practitioners who've actually deployed it. Skip this if you need EDR breadth,network detection, process monitoring, threat hunting,or if your fleet runs Windows or Linux; Do Not Disturb is intentionally narrow, solving one problem that most commercial EDR products don't prioritize at all.
Mac-focused security teams with limited budgets should start with Knockknock to audit persistence mechanisms that commodity malware relies on, especially rootkits and launch agents that traditional antivirus misses. It's free and open-source, so deployment friction is near zero and you can inspect the code yourself. Skip this if you need real-time prevention or cross-platform coverage; Knockknock is a forensic scanner for macOS, not an EDR replacement.
