How do I completely uninstall applications on a mac?

This is a great open-source tool for visualizing disk space on your Mac, no paid subscriptions required. It essentially lets you see exactly what’s taking up storage on your drive with a color-coded map, allowing you to quickly spot large apps, files, and folders you no longer need, which is especially helpful when learning how to uninstall applications on Mac to free up space.

Usage Guide: Open GrandPerspective, select your Mac’s startup disk to run a full scan. Once the scan finishes, you’ll see a visual breakdown of your storage, where each colored rectangle represents a file or folder sized by its space usage. First, locate large blocks that correspond to unused apps or their leftover files. Next, use this visual to identify which apps you want to remove, then follow standard or manual uninstall steps to delete them. Finally, re-scan your drive to confirm the space has been freed up. This method gives you a clear, visual way to understand your storage usage, making it easier to master how to uninstall applications on Mac and keep your drive clutter-free.

It is particularly useful for identifying space-hogging apps before uninstallation, conducting full storage audits, troubleshooting a full Mac startup disk, or clearing space for system updates and large files.
