Apps · Offloading and restoring apps
Is anything deleted when I offload an app?
Short answer: No. Offload copies and checks everything on your fast drive before removing originals; if anything fails, nothing changes. Deleting only happens if you click Remove, and that goes to the Trash.
No. Offload copies the app and its data to your fast drive and checks the copy before removing anything from your Mac. If any step fails, nothing is changed and your data is left untouched — the app is never left half-moved.
The only way to delete an offloaded app is to click Remove yourself, and even that goes to the Trash.
