History Events

The Sleep history is the calendar view within a Sleep Aid window, this view makes it easy to see when the screen was off, when the Mac suffered from insomnia, when it experienced a potential problem, when it was woken to display a notification, errors it encountered, OS updates, setting changes and even notes that you record yourself.

Clicking on an item in the calendar view, will update the sidebar to show more details about that item. Double clicking an item, will open a separate window with its detailed information. This is useful if you wish to compare two events to see if there were any differences.

Most insomnia events can be safely ignored, but are still shown in the calendar, allowing for you to see what's going on when the Mac wakes, and why.

History Notes

Sleep Aid uses a variety of note icons to display certain events. These are color coded. Green icons represent information, Orange icons are things that Sleep Aid thinks you should check, while Red icons are actual problems.
