v1.0.1
0bf0735

whatwatts is a lightweight menu bar app for seeing what your Mac is doing right now when it is plugged in: charger wattage, battery flow, and an optional system-power estimate.

What is new in v1.0.1:

  • same app build as v1.0, with the docs and install flow aligned to the current main
  • clearer trust and first-launch instructions
  • direct one-line Terminal commands for Intel and Apple Silicon
  • screenshots and release notes aligned with the current repo state

Downloads:

  • whatwatts-intel.zip for Intel Macs
  • whatwatts-apple-silicon.zip for Apple Silicon Macs

Source is public in this repo, so you can inspect exactly what the app does before running it.

Low-power mode behavior:

  • Idle: checks once a minute to stay lightweight
  • After plugging or unplugging a charger: updates once a second for 20 seconds
  • System power: shown as a 60-second average unless Always Live Updates is enabled

Trust and first launch:

  • If macOS blocks the app, you can always use System Settings > Privacy & Security > Open Anyway
  • If you prefer Terminal, there are two options:
  • Use a test run command if you want to launch whatwatts from ~/Downloads first. This does not require an administrator password.
  • Use an install command if you want to move it into /Applications. This usually requires an administrator password.
  • Pick the command that matches your Mac, paste it into Terminal, and press Return.

Intel test run:

curl -L https://github.com/git-anish/whatwatts/releases/download/v1.0.1/whatwatts-intel.zip -o ~/Downloads/whatwatts-intel.zip && ditto -x -k ~/Downloads/whatwatts-intel.zip ~/Downloads && xattr -dr com.apple.quarantine ~/Downloads/whatwatts-intel.app && open ~/Downloads/whatwatts-intel.app

Apple Silicon test run:

curl -L https://github.com/git-anish/whatwatts/releases/download/v1.0.1/whatwatts-apple-silicon.zip -o ~/Downloads/whatwatts-apple-silicon.zip && ditto -x -k ~/Downloads/whatwatts-apple-silicon.zip ~/Downloads && xattr -dr com.apple.quarantine ~/Downloads/whatwatts-apple-silicon.app && open ~/Downloads/whatwatts-apple-silicon.app

Intel install:

curl -L https://github.com/git-anish/whatwatts/releases/download/v1.0.1/whatwatts-intel.zip -o ~/Downloads/whatwatts-intel.zip && ditto -x -k ~/Downloads/whatwatts-intel.zip ~/Downloads && sudo rm -rf /Applications/whatwatts.app && sudo mv ~/Downloads/whatwatts-intel.app /Applications/whatwatts.app && sudo xattr -dr com.apple.quarantine /Applications/whatwatts.app && open /Applications/whatwatts.app

Apple Silicon install:

curl -L https://github.com/git-anish/whatwatts/releases/download/v1.0.1/whatwatts-apple-silicon.zip -o ~/Downloads/whatwatts-apple-silicon.zip && ditto -x -k ~/Downloads/whatwatts-apple-silicon.zip ~/Downloads && sudo rm -rf /Applications/whatwatts.app && sudo mv ~/Downloads/whatwatts-apple-silicon.app /Applications/whatwatts.app && sudo xattr -dr com.apple.quarantine /Applications/whatwatts.app && open /Applications/whatwatts.app

What the commands do:

  • curl -L ... downloads the release zip from GitHub
  • ditto -x -k ... unzips the app
  • xattr -dr com.apple.quarantine ... removes macOS quarantine so the app can launch
  • open ... launches the app
  • sudo rm and sudo mv only appear in the install version because moving the app into /Applications usually needs admin access

Checksums:

  • Intel: 033e4057c059b577fed7c7dacd748f0e6abf4068a922d0afbc5659459098b597
  • Apple Silicon: 60b352715a084f5e38bbb7e3ce912d01b824217fbb52b2430ffb72d09203d8c7

Note: the SMC system-power value is inspired by SAP Power Monitor and uses private Apple interfaces. It works now, including on an Intel Mac we tested, but it may stop working on future macOS or hardware revisions.
