Way 5: Restart Mac or update system

Restart your computer or update its system is helpful to clean up Mac storage too. Restarting your Mac can refresh the system and clear some application caches to free up disk space. You can also update macOS to optimize its operation. And you may have downloaded the macOS firmware but haven't installed it. Install the latest update to clean up storage.

Now you must free up enough storage to download the firmware package. Try to download it again and complete the removal process with 4uKey.
