iTunes crashing after Time Machine reinstall

After my laptop drive failure, installation of a new disk, and recovery from Time Machine, iTunes failed to open successfully, reporting,


"You Do Not Have Enough Access Privileges For This Operation"


I’d excluded my Shared user account from the Time Machine configuration, which apparently causes problems for iTunes.

The resolution is to execute the following shell script,


sudo mkdir -p /Users/Shared
sudo chmod -R 1777 /Users/Shared
