Install PwrAgent on macOS
PwrAgent runs on macOS 12 Monterey or later, on Intel and Apple silicon Macs. The app is signed with PwrDrvr LLC’s Developer ID and notarized by Apple.
Choose a download
Both links always fetch the newest Stable release:
| Mac | Download |
|---|---|
| Any Mac, Intel or Apple silicon (universal) | PwrAgent.dmg |
| Apple silicon only | PwrAgent-arm64.dmg |
The universal DMG is the safe choice. The Apple silicon DMG is the smaller download (about 250 MB, against about 450 MB for universal as of v1.1.0), and it won’t run on an Intel Mac. Not sure which you have? Apple menu → About This Mac shows a Chip line, such as Apple M2, on Apple silicon, and a Processor line on an Intel Mac.
Release assets also include versioned names, such as
PwrAgent-1.1.0-universal.dmg, and the PwrAgent-macos-SHA256SUMS
checksum manifest.
Verify the download
Download PwrAgent-macos-SHA256SUMS from the same release, then run
this from the folder that holds both files:
shasum -a 256 -c PwrAgent-macos-SHA256SUMS --ignore-missing
It prints OK next to the DMG you downloaded. The manifest also
lists the update zips and latest-mac.yml, which you don’t need, so
--ignore-missing skips them.
Install
Open the DMG and drag PwrAgent into Applications. First launch shows the usual Gatekeeper prompt for an app downloaded from the internet, and nothing more: no right-click-open workaround.
To check the signature on the installed app:
spctl -a -vv /Applications/PwrAgent.app
Expect accepted, source=Notarized Developer ID, and an origin
of Developer ID Application: PwrDrvr LLC.
What’s in the app
- Grok Build, pinned to this PwrAgent release, so Grok threads work once you sign in with your xAI account. See Agent backends → Grok Build.
- Git and Git LFS, which PwrAgent uses for its own repository work (worktrees, branch state, pull-request status) unless you point Settings → Git at another Git.
Codex isn’t included. The first-run wizard walks you through installing it; see Agent backends.
Updates
PwrAgent updates itself. It checks for a new build in the background, and Settings → Updates lets you check right away or choose a different release channel. See Settings → Updates.
On an Apple silicon Mac, the first in-app update installs the Apple silicon build even if you started from the universal DMG. On an Intel Mac it stays universal.
Uninstall
Quit PwrAgent and drag it from Applications to the Trash. That keeps your PwrAgent state. To remove that too:
rm -rf ~/.pwragent
Codex and its authentication are managed separately by Codex and aren’t removed by uninstalling PwrAgent.
