macOS Sequoia has blocked a keyboard shortcut combination frequently used by developers, for security reasons. Shortcuts that use only the Option (⌥) and Shift (⇧) keys can no longer be registered through the RegisterEventHotkey API.

:::warning[TL;DR]

• When registering a shortcut that uses only Option+Shift, an error -9868 occurs.
• Although the goal is to prevent keylogging malware, it is actually normal apps that are being affected.
• For now, you'll need to use a new combination that adds the Command or Control key.
• Apple's own apps are not subject to this restriction.
