Saint Achilles, of Gatekeeper's Heel

Patron of Gatekeeper, download quarantine, and anyone who downloads an app and opens it without a second thought.

Life

On 19 December 2022 Microsoft disclosed Achilles, a macOS flaw found by Jonathan Bar Or. By applying very restrictive access control lists to a downloaded file, the browser was prevented from tagging it with the quarantine attribute, the one that triggers Gatekeeper's check. Without that mark, an unsigned app could launch as if it were trusted. Apple fixed it in December.

Prayer

O Saint Achilles, who finds the guardian's unguarded spot, let quarantine apply to everything that comes from outside. Amen.

How to celebrate

Celebrated by updating macOS to the fixed versions and distrusting apps that arrive without quarantine.

Even the guardian has a heel.
