This post will show you how to set location based reminders from the reminders app on your mac :)
its a little backwards, so I thought I’d explain it here for others.
1) open reminders.app
2) add a new reminder, give it a name, eg ‘dont forget keys’
3) double click the reminder you just added, a popup will appear
4) tick ‘location’
5) it might ask you for permission to use your location, if it does, then let it :)
6) pick the settings – you can type addresses, etc and select arriving or leaving
