Recently I downloaded some updates from the Mac App Store including the macOS high Sierra update and a few other security and application updates. However, presumably because of a corrupted download, these applications fail their integrity checks and don't run on the system.
In addition, when I retry them, they begin downloading from some point midway. For example, the "iTunes + Remote Desktop Client + Safari + Security Patch 2018-001" for macOS Sierra, which measures 1.12 GB, always starts off downloading from the ~365MB point. After downloading again, the update fails.
Is there a way to clear the Mac App Store update data so that I can download everything afresh?
I'm on a MacBook Air 2017 edition, running macOS Sierra 10.12.6.
