I'm trying to build an ADHD task reminder for OSX, but I have very limited programming experience. Could you advise me please on the easiest method to accomplish it? High-level overview: From 9.30am to 4.30pm, on the hour, and at 30 mins past the hour, go to the calendar* * (this could be any of Todoist / iCal / Gcal, whichever is easiest to make work. I have multiple calendars in iCal, so it would have to pick up only the task calendar, not all calendars) If nothing there, do nothing. If a task/event is set, 5 minutes before the event, display a small dialogue box with a reminder to wrap up the previous task, and a click button for OK to dismiss. At the time of the event, blackout the screen, display large text with the name of the new event/task, and a click button for OK to dismiss. Quite simple, but I've tried to build it in AppleScript & Automator & not got anywhere. Any advice on simplest way to make this happen? iCal reminders etc don't do it for me, I need a full screen blackout.
