Tencent Lemon Cleaner

Tencent Lemon Cleaner is a macOS‑only utility that performs deep system cleaning and provides real‑time status information. It scans for excess files, large and duplicate items, similar photos, and browser privacy data, then offers one‑click removal to free disk space. The tool also includes specialized scans for popular applications such as WeChat, QQ, Xcode, and Sketch, applying tailored cleaning rules for each.

In addition to file cleanup, the application displays hardware metrics in the menu bar, including disk usage, CPU temperature, and fan speed, and it can detect network activity and alert users when the camera or microphone is in use. A lightweight status‑window mode enables quick termination of slow‑running apps and immediate space recovery.

Two distribution variants are offered: a full version, which is notarized by Apple and contains all features (including application uninstall), and an App Store version that omits certain capabilities due to store restrictions. The software targets macOS 10.11 and later, including Mojave, and is positioned for users who want a comprehensive yet straightforward way to keep their Mac clean and monitor system health.
