Sort Action Center Items by Time to Make Them More Useful
By default, Action Center on Mac sorts items manually. That’s okay for some, but if you’d rather sort your notifications with the most recent notification at the top, iDownloadBlog points to an option you might have missed.
If you go to System Preferences> Notifications, you will see the option to change the Sorting of the Action Center. If you change it to Timed, the most recent notification will always be at the top, making tracking a little easier.
