Bottom Line: Exercise Caution. You should NOT delete the entire Containers folder, but it is 100% safe to delete container folders belonging to apps you have uninstalled.
What is the macOS Containers Folder?
Located at ~/Library/Containers on macOS, this directory holds sandboxed data for apps installed via the Mac App Store.
Under macOS App Sandbox security rules, Mac App Store applications are restricted from writing to general user directories. Instead, each app receives an isolated container folder holding its own private Data/Library/Caches, Preferences, and Documents.
Over years of Mac usage, uninstalled App Store software leaves orphan container directories behind, hoarding 10 GB to 40 GB+ of hidden SSD space.
Can You Delete Containers?
⚠️ Caution Required.
- Do NOT delete the main Containers directory: Deleting active containers will reset sandboxed Mac apps (like Microsoft Outlook, Xcode, or Apple Mail) and wipe un-synced app data.
- Safe to delete orphan containers: Deleting container folders for apps you already dragged to the Trash is completely safe.
