I have an Automator Event that opens and run an app in Mac Mail.
It has no end time, it just runs the app.
How do I just have a start time, no end time.
Also I add notes into calendar to remind to do things so I need no end time, just start time.
How do I do this?
I'll deal with adding notes to the Calendar app first because I think I can knock that one out quickly. Try the following and see if it meets your needs.
1. Create an event and name it. I'd probably use something that reminds me of the task.
2. Set the end time for the same time. The current version of Calendar will let you do this.
3. Set an alert to occur at the time of the event. That forces the event to automatically pop up in your notifications. You could also set the notice to go off before the event.
4. If the text you put in the event title isn't enough, add additional text in the notes field.
BTW have you considered using the Reminders app to do this? I used to use Calendar to do this, but I found that my Calendar was getting too crowded as reminders got mixed in with actual appointments.
It has been a while since I ran Automator based on Calendar alarms and that used to get a little twitchy each time Apple updated Automator. This trick might work for that as well.
If you can tell us what this is doing, I might be able to help with it. What version of the OS are you running? Automator's capabilities have changed several times over the years.
