CleanMyMac X is an all-in-one Mac maintenance utility from MacPaw that deeply cleans junk files, system caches, broken downloads, and large unused files to reclaim storage space. It also includes tools for app uninstallation, malware removal, RAM optimization, and performance monitoring. With regular updates and Apple Silicon support, it ensures your Mac runs smoothly without manual tinkering.

DaisyDisk is a specialized disk space analyzer for macOS that uses a stunning interactive sunburst diagram to visualize how storage is being used across drives and folders. It scans quickly to reveal large files, apps, and hidden caches, allowing users to drill down and manually delete items to free up space. Unlike full-suite cleaners, it focuses purely on analysis and safe, precise manual cleanup without automation or system tweaks.

Onyx is a free, powerful macOS utility from Titanium Software that offers comprehensive system maintenance, cleaning, and optimization tools. It enables users to clear caches, logs, and temporary files, repair disk permissions, manage fonts and applications, and run advanced scripts tailored to specific macOS versions. Ideal for manual deep cleaning, it provides granular control without subscriptions or ads, though it requires some technical knowledge.

Gemini 2 by MacPaw is a specialized Mac app designed to find and remove duplicate files, helping users reclaim valuable disk space without manual hunting. It employs advanced content-based scanning algorithms to detect identical files across your drive, folders, or external storage, even if they have different names. The app features a sleek interface with visual previews for safe review and deletion, including options for automatic backups.

AppCleaner is a lightweight, free utility designed specifically for uninstalling Mac applications by removing not just the app itself, but also associated files like preferences, caches, and support files that standard deletion misses. Users simply drag an app icon onto the AppCleaner's window, where it scans and lists all related items for selective deletion. While focused narrowly on app removal, it excels at preventing clutter from incomplete uninstalls without unnecessary bloat.

CCleaner for Mac is a lightweight system optimization tool designed to clean junk files, caches, logs, and browser data to free up disk space and boost performance. It includes features like app uninstallation, startup item management, software updates, and privacy protection through secure file deletion. While effective for basic maintenance, it relies on a free version for core cleaning and a Professional upgrade for advanced tools like automatic updates and priority support.

Hazel is a Mac automation utility from Noodlesoft that monitors folders and applies user-defined rules to organize, move, delete, or archive files based on attributes like age, type, size, or name. It helps maintain a clean file system through proactive, set-it-and-forget-it automation rather than manual scanning or one-time cleanups. While effective for folder-specific tidying, it lacks comprehensive system junk removal, cache clearing, or duplicate detection typical of dedicated Mac cleaners.

TinkerTool is a lightweight macOS utility that provides access to hidden system settings and performs targeted maintenance tasks like clearing caches, managing fonts, resetting launch services, and uninstalling applications. It empowers users to tweak macOS preferences through a graphical interface without Terminal commands, focusing on system optimization rather than broad junk removal. While effective for specific cleaning and diagnostic needs, it lacks automated scanning for duplicates, large files, or malware common in full Mac cleaners.

MacBooster, developed by iMobie, is an all-in-one Mac optimization suite designed to clean junk files, remove duplicates, manage large/old files, and boost system performance. It also includes privacy tools to clear browsing data and real-time protection against threats, alongside an app uninstaller and startup optimizer. While it offers a user-friendly dashboard for one-click maintenance, its effectiveness is solid but not superior to top competitors or macOS built-in features.

Disk Inventory X is a free macOS disk space analyzer that uses interactive treemaps to visualize how storage is being used across drives and folders. It scans disks quickly to highlight large files and directories, helping users pinpoint space-consuming items. Although excellent for diagnosis, it lacks built-in cleaning or deletion tools, requiring manual action outside the app. As a Mac cleaner solution, it serves primarily as an analytical precursor to cleanup rather than a comprehensive management tool.
