For whatever reason, non-admin users are permitted to install and update software on Macs by default. This is highly undesirable in a CI environment, and especially so in one where the underlying resources are shared across testing contexts. Block this by altering system settings to require admin access.
Further through experimentation, it was found that rosetta (allows arm64 macs to run x86_64 code) ignores the admin-required settings. To give pause to any users trying to run
softwareupdate
, move it out of general reach. This isn't a perfect solution, but should at least discourage all simple usage.
