EtreCheckPro vs htop

EtreCheckPro is a macOS diagnostic tool for investigating problems on a Mac. It detects more than 70 specific problems, distinguishes major from minor issues, and produces an anonymous text report for sharing online. It can identify security configuration problems and detect and remove malware. The app also shows storage use and helps address storage problems, but those functions require Full Disk Access. The free version supports command-line use from Terminal or ssh and can run from the Downloads folder without installation. It works on Intel and Apple Silicon Macs running macOS 10.13 through macOS 27. The optional Power User package adds computer-generated step-by-step solutions and detailed views of hardware, operating system, storage, networking, software, and performance, plus system Analytics and Insights charts. The free download costs nothing and includes basic reports and diagnostics. The Power User package costs $19.99, paid once and covers up to six different computers. Technical support is provided by email, with the company striving to respond within 48 hours.

htop is a free, text-mode interactive process viewer for Linux and macOS. It runs in console or X terminals and requires ncurses, offering a command-line interface for watching and managing running processes. Current releases also list FreeBSD, NetBSD, OpenBSD, DragonFly BSD, and Solaris as supported systems. The project, founded in 2004, is distributed as source code on GitHub and as pre-compiled packages from operating-system distributors, with installation examples for Debian, Fedora, Gentoo, and Arch Linux; Homebrew includes it for macOS. Its display can show Unicode Braille graphs and a Unicode tree view, including visual support for large processor counts. Users can set I/O scheduling priority and CPU affinity, choose dark or light terminal themes, and customize header meters. The memory percentage covers process-used memory; htop does not provide a per-process SWAP column.
