How can I delete partially downloaded macOS installer files? I was downloading the Mojave installer using the following command:
sudo softwareupdate --fetch-full-installer --full-installer-version 10.14.6
When the download reached about 50%, I had to cancel it by keyboard interrupt. My system storage is now reduced by 3GB, and I can't seem to find any partial downloads in /Applications/.
So how do I delete the partially downloaded installer to recover the lost space?
man softwareupdate says that

Updates are downloaded to /Library/Updates

Can you check and see if it's at this location?
