Apps · Offloading and restoring apps
Can I open an app while it's offloaded?

No. An offloaded app is archived on your fast drive and removed from your Mac, so it doesn't appear in Applications and can't be launched. That's what lets Offload free the most space.
When you need it again, click Restore on the Offloaded tab — it comes back with its data, ready to use. If you want an app to stay usable from the drive, use Move instead.
