GrandPerspective

Description

GrandPerspective is a free, open-source disk usage analyzer for macOS.

Its primary purpose is to help you scan your disk and see which files and folders are taking up most of your space. The program uses a "so-called treemap" to show you a general view of your occupied space. Each file is displayed as a rectangle with an area that reflects its file size. Multiple files from the same folder are grouped, but their placement is arbitrary.

GrandPerspective runs on macOS only. The latest version, 3.8.1, needs macOS 14 or later on an Apple silicon or Intel Mac. It doesn't run on Windows or Linux.

The developer's official site offers GrandPerspective as a free download, and the same app costs $2.99 in the Mac App Store.

Note: This software is one of the few up-to-date macOS disk usage visualization tools that are using treemaps. GrandPerspective is the macOS alternative to other similar software such as WinDirStat, SpaceSniffer (both run on Microsoft Windows OS) or KDirStat (runs on Linux). There is another app for macOS named Disk Inventory X. Its developer's site lists version 1.3, for macOS 10.13 to 10.15.

If you use an older version of Mac OS X you might want to download an older version that will work. The author recommends the following versions (you can find them in the official download area on SourceForge).

For macOS 11, 12 and 13, download GrandPerspective 3.7.2. For macOS 10.14 and 10.15, download GrandPerspective 3.3. For macOS 10.9 to 10.13, download GrandPerspective 3.0.1. For Mac OS X 10.7 and 10.8, download GrandPerspective 1.7.0. For Mac OS X 10.6, download GrandPerspective 1.5.3. For Mac OS X 10.5 and PowerPC processors, download GrandPerspective 1.5.1.
