Preparation guide

  1. Try a short nonprivate sample in a blank local document. Record wrong characters, delay or absent input; keep the actual sample off this page.

  2. If no built-in keys respond, connect safe power. Apple notes an unseen low-battery alert can be involved; an owned external keyboard may help reach settings.

  3. Inspect Slow Keys under Accessibility → Keyboard and Mouse Keys under Pointer Control. Preserve accessibility settings you depend on. On older macOS, select the matching version of Apple’s guide.

  4. Check the selected input layout when characters differ from key labels. Compare the same sample in a second local app with the layout unchanged.

  5. Retain the affected key group, input category and app difference. If basic typing remains unusable, contact Apple; leave keycaps in place.
