Power Monitor 1.2.1 has been tested and verified to run on the following OS versions:

• macOS 15.0 beta 1

• macOS 13.6.7

Changes

A new Power Graph window has been added. This allows the measured values to be graphically displayed and evaluated in more detail.

• Values can be pinned by just clicking into the graph.
• The graph can be freely zoomed and scrolled.

App now includes a journal function that can be used to store and evaluate power consumption over a longer period of time.

• The journal (or individual entries) can be exported as a CSV or JSON file.
• Journal entries can be automatically deleted after a period of time specified by the user.
• Journal entries can be deleted manually at any time.
• The journal function must be explicitly activated by the user.

Times when the Mac takes a Power Nap can now be excluded to avoid skewing the statistics.

Support for the Electricity Maps API has been updated.

Added new command-line arguments to make it easier to read power data and to allow access to journal data (e.g. using an extension attribute for a Jamf Pro server).

Power Monitor 1.2.0 has been tested and verified to run on the following OS versions:

Changes

• Added the ability to toggle between all measurements and today’s measurements.
• Capture and display times when the Mac takes a Power Nap.
• Users can now choose between displaying the power consumption or the electricity costs.
• Hovering the mouse pointer over the graph now displays the measured power value and timestamp at that point in the graph.
• Users can now delete all measurements directly from the application.
• Power Nap can now be enabled and disabled directly in the application.
• Clicking on the maximum power now displays the corresponding measurement in the graph.
• Intervals during which the Mac is in sleep mode or powered off can now be displayed.
• Log entries related to sleep/wake events can now be displayed in the application’s new console window. Clicking on a measurement in the graph selects the log entry prior to the measurement. This will help users to determine the reasons for dark wakes.
• Processes preventing sleep can be displayed.
• App can be set to launch at login.
