OverSight for Mac

Stop unwanted camera and microphone use with OverSight

OverSight is a no-cost utility that watches your Mac's webcam and microphone for unexpected activity. Malicious programs can sometimes switch these devices on without your consent, so OverSight keeps a log and alerts you whenever the camera or mic powers up.

What it scans for

• Processes that trigger the camera or microphone and the time they become active
• Unexpected device activations that occur when you're not using the machine

How it helps you respond

• Lets you see which application or process is enabling the hardware so you can identify suspicious behavior
• Gives you the option to permit or block specific processes, allowing legitimate apps while stopping unauthorized access

Practical benefits and typical uses

• Detects software that piggybacks on legitimate actions (for example, programs that open the camera during video calls and could allow interception)
• Provides a straightforward way to spot privacy intrusions without complicated setup

Interface, trade-offs, and limits

• The interface is simple and easy to navigate, though it lacks advanced visual polish typical of commercial products
• OverSight is free and useful as a basic protective layer, but it may not stop every threat: malware with deep system privileges can potentially bypass its checks

Alternative to consider

• Avast Mac Security Free — a recommended replacement that offers broader protection for macOS users
