About OpenDisk for Mac
OpenDisk is a free and open-source disk usage analyzer for Mac. It visualizes your drive as an interactive sunburst chart, where each ring represents a level of folders and each segment’s size reflects how much space it uses.
This makes it easy to see at a glance which folders dominate your storage and to drill into them with a click. It is a great free alternative to paid visual analyzers.
Use OpenDisk to find where space went, then remove large files you no longer need or move them to an external drive.
