About:
Unshaky is a lightweight macOS application designed to mitigate the 'double key press' issue commonly found on Apple's butterfly keyboard mechanism. It operates by intercepting keystrokes and applying a software-based debounce algorithm to filter out unintended repeated inputs. This provides a practical software workaround for hardware defects, improving typing accuracy without requiring physical repairs.

Key Features:

Software-based debounce algorithm to filter double presses
Minimal system resource usage with background operation
Customizable delay settings for specific keys
Menu bar interface for easy control and status monitoring

Use Cases:

Mitigating hardware defects on MacBook butterfly keyboards without repair
Improving typing accuracy for users experiencing accidental key repeats

Alternatives:

Karabiner-Elements – More complex but offers deeper keyboard customization; Unshaky is specialized specifically for butterfly keyboard debounce issues.
