Standaloneupdaterdaemon Info

Occasionally, users notice StandaloneUpdaterDaemon consuming a significant percentage of CPU or memory. This usually happens for one of three reasons:

The Fix: If the process is slowing down your Mac, simply force-quitting it via Activity Monitor is usually safe. It will automatically restart the next time a Microsoft app is opened or during the next scheduled check.

If the daemon is causing persistent issues, you can disable it: standaloneupdaterdaemon

Windows (SC command as Administrator):

sc stop "AdobeStandaloneUpdaterDaemon"
sc config "AdobeStandaloneUpdaterDaemon" start=disabled

macOS (launchctl):

sudo launchctl unload /Library/LaunchDaemons/com.adobe.standaloneupdater.plist

Caution: Disabling leaves your software vulnerable. A better approach is to schedule manual checks once a week.

This usually indicates a firewall or proxy issue. Ensure the daemon is allowed through the firewall and that system proxy settings (HTTP_PROXY env variable) are correctly passed to background services. The Fix: If the process is slowing down

| Failure | Recovery Action | |---------|----------------| | Download interrupted (network) | Resume from last byte; keep partial download with .part suffix. | | Power loss during apply | On reboot, daemon detects stale lock; restores from backup before retrying. | | New version crashes immediately | Health check fails → rollback in < 30 seconds. | | Disk full during download | Pause updates, emit alert, resume after space freed (poll every 5 min). | | Signature verification fails | Abort, increment failure counter, notify admin, do not apply. |

The standaloneupdaterdaemon pattern is slowly being replaced by more modern update mechanisms: daemon detects stale lock

However, for legacy enterprise software and cross-platform consumer apps, the standalone updater daemon remains a necessary trade-off: it provides seamless updates but at the cost of an extra background process.
