Standaloneupdaterdaemon (2026 Update)
StandaloneUpdaterDaemon is a background process typically associated with Microsoft OneDrive
on macOS. It functions as a specialized utility to keep the application updated independently of the standard Mac App Store or macOS software update systems. Apple Support Community Key Characteristics
It is part of the Microsoft software suite, specifically found within the Microsoft OneDrive application package. File Location:
On a Mac, the executable is usually located deep within the app's contents:
/Applications/OneDrive.app/Contents/StandaloneUpdaterDaemon.xpc/Contents/MacOS/StandaloneUpdaterDaemon
It monitors for new versions of OneDrive and installs them in the background to ensure you are always running the latest features and security patches. Apple Support Community Is It Safe?
In most cases, yes. It is a legitimate component of the OneDrive installation. However, users often notice it because: Apple Support Community Security Alerts:
Following a macOS update (like Ventura or Sonoma), the system may flag it under Login Items Allow in the Background
as being from an "Unknown Developer". This happens if the specific background daemon isn't digitally signed in a way the OS recognizes, even if the main app is. Malware Risks:
Security researchers have noted that attackers can sometimes abuse legitimate-sounding names or hijack update processes to side-load malware. If you see this process but
have OneDrive installed, it could be a sign of suspicious activity. Apple Support Community Management and Removal Disabling: You can toggle it off in System Settings > General > Login Items
under "Allow in the Background". This may stop OneDrive from updating automatically, requiring you to manually update or reinstall the app later. Verification: You can use Activity Monitor
to inspect the process. Selecting the process and clicking the "i" (Inspect)
icon can reveal its parent folder, confirming if it belongs to Microsoft. Full Removal:
To get rid of it entirely, you typically need to uninstall Microsoft OneDrive.

The StandaloneUpdaterDaemon is a background process on macOS used primarily by Microsoft to handle updates for applications like OneDrive and Microsoft Office through the Microsoft AutoUpdate (MAU) tool. standaloneupdaterdaemon
In common technical "stories" found in user forums, this process often appears as a source of frustration when it becomes unresponsive or prevents apps from opening:
The OneDrive Bug: Users have reported scenarios where the OneDrive app for macOS fails to open entirely. The solution often involves a "story" of manual intervention: disabling internet, navigating into the OneDrive app's package contents, and deleting the StandaloneUpdaterDaemon.xpc file to force the app to reset.
The Update Freeze: When Microsoft Office updates get stuck, technicians often advise opening the Activity Monitor to find and "Force Quit" the StandaloneUpdaterDaemon process.
Technical Nature: It is technically an XPC Service, which is a specialized Apple framework that allows different parts of an application to communicate securely and perform background tasks like checking for new software versions without interrupting the main user interface. How to manage it
If you are seeing this process in your Activity Monitor and it is causing issues (like high CPU usage or preventing updates): Open Activity Monitor (via Spotlight). Search for StandaloneUpdaterDaemon.
Select it and click the "X" button at the top to quit the process.

Understanding StandaloneUpdaterDaemon: What It Is and How It Works
If you’ve been poking around your Activity Monitor on macOS or scrolling through background processes on your computer, you might have stumbled upon something called StandaloneUpdaterDaemon. While the name sounds like something out of a sci-fi movie, it’s a standard utility designed to keep your software running smoothly.
Here is a deep dive into what this process does, why it’s running, and whether you should be concerned about it. What is StandaloneUpdaterDaemon?
At its core, StandaloneUpdaterDaemon is a background process (a "daemon") typically associated with the Adobe Creative Cloud suite or specific software installers.
In the world of computing, a "daemon" is a program that runs in the background rather than under the direct control of the user. Its primary job is to wait for a specific trigger—like a scheduled time or a request from another program—and then execute a task.
The "StandaloneUpdater" part of the name refers to its specific mission: checking for, downloading, and preparing software updates without requiring the main application (like Photoshop or Acrobat) to be open. Why is it running on my computer?
You will most commonly see this process if you have Adobe products installed. It acts as a bridge between the software on your hard drive and the servers where updates are hosted. Its main responsibilities include:
Silent Updates: Checking for security patches and feature improvements in the background.
Integrity Checks: Ensuring that the installation files are not corrupted.
Installation Management: Handling the actual update process so that it doesn’t interrupt your workflow while you’re using the app. Is it safe? applies updates (immediate or scheduled)
Yes. In almost every case, StandaloneUpdaterDaemon is a legitimate part of your software's ecosystem. It is signed by the developer (usually Adobe) and is not a virus or malware.
However, like any background process, it can sometimes behave unexpectedly. Users occasionally report:
High CPU Usage: This usually happens when the daemon is actively downloading or installing a large update.
Multiple Instances: Sometimes, if an update gets "stuck," you might see the process appearing more than once in your task manager. Can I disable it?
While you can force-quit the process in Activity Monitor or Task Manager, it will likely restart itself the next time you launch an Adobe app or reboot your computer.
Disabling it permanently is generally not recommended. Updates often include critical security patches that protect your system from vulnerabilities. If you disable the updater, you leave your software—and your entire computer—exposed to potential bugs and exploits. How to troubleshoot high CPU usage
If you notice StandaloneUpdaterDaemon is hogging your system resources:
Wait it out: It’s often just finishing a heavy update. Give it 10–15 minutes.
Restart the Creative Cloud Desktop App: This often resets the updater’s logic.
Update Manually: Open your Adobe Creative Cloud app and check for updates manually. Once the update is complete, the daemon should go back to its "sleeping" state.
Reinstall: If the process is constantly crashing or using 100% CPU, a clean reinstall of the Adobe Desktop Service usually fixes the corruption.
StandaloneUpdaterDaemon is a quiet assistant that ensures your professional tools stay up to date. While it might occasionally "spike" in activity, it is a vital component for anyone using modern creative software.
Are you seeing this process cause significant slowdowns on your machine, or were you just curious about the name?
Overview
StandaloneUpdaterDaemon is a background service that runs on client machines to manage application updates independently of a central GUI. It checks for updates, downloads and verifies packages, applies updates (immediate or scheduled), rolls back on failure, reports status, and enforces update policies set by administrators.
How to Identify a Malicious Imposter
Cybercriminals often name malware to mimic legitimate system processes. Here’s how to verify that your standaloneupdaterdaemon is genuine:
Error: "StandaloneUpdaterDaemon prevents shutdown"
Some daemons hold a mutex during an update. Force quit via Task Manager or wait 2-3 minutes for a timeout.
