I thought I would post about something which I've just noticed has been made possible with the arrival of the M1 (ARM) chip in the latest model of Apple Macs - notifications from Hubitat within macOS.
I have my Hubitat linked with HomeKit which allows for status notifications only certain devices (e.g. contact sensors) - however my use case was to receive a notification on-screen when someone was at the door. Previously I looked at workarounds involving a push-notification relay service, however I wasn't able to get it working.
I then noticed that on my new MacBook I could install iOS and iPadOS apps and run them on the device - so I installed Hubitat, set it up, and added it to the Notifications app - low and behold, the notifications started appearing, job done!
