Reminders & timers·MacPredicted — not yet device-tested

Set a reminder on your Mac with Siri

Quick answer

"Remind me to send the report at 4pm" and Siri adds it to Reminders on your Mac, alerting you at that time across your devices. Add a list — "add buy stamps to my errands list" — and Siri files it there. It syncs to your iPhone and iPad automatically.
