CleanMyMac HealthMonitor High CPU: How to Fix It for Good
How to Fix CleanMyMac HealthMonitor High CPU
If your Mac is running hot, fans are spinning, and Activity Monitor shows CleanMyMac X HealthMonitor consuming 80% to 100% CPU, here is the quick breakdown:
- The Cause: HealthMonitor gets stuck in an infinite polling loop due to permission timeouts, APFS snapshot recalculations, or corrupted preference caches.
- Why Force Quitting Fails: A hidden startup script in
~/Library/LaunchAgentsinstructs macOS to restart the daemon immediately whenever it exits. - The 3 Solutions:
1. Turn off the Menu and background monitoring in CleanMyMac Settings.
2. Delete the
com.macpaw.CleanMyMac4.HealthMonitor.pliststartup script from your Library folder. 3. Switch to a zero-daemon cleaner like DiskCompanion ($29 lifetime license for 3 Macs) that runs only when open and never installs background helpers.
You notice your MacBook suddenly getting warm to the touch. The battery percentage drops noticeably faster than usual, and your cooling fans spin up to full volume even though you are only browsing the web.
You open Activity Monitor, sort processes by "% CPU", and find the culprit: CleanMyMac X HealthMonitor is pinned at 85%, 100%, or even 120% CPU usage.
It is a frustrating irony: software downloaded specifically to speed up your Mac is now the single biggest reason your computer is overheating and slowing down.
In this guide, we explain why CleanMyMac HealthMonitor gets stuck in high CPU loops and show you how to stop it temporarily, disable it inside the app, or remove its background startup scripts permanently.
Why CleanMyMac HealthMonitor Spikes CPU & Drains Battery
CleanMyMac X is not just a standard application that runs when you open it. By default, its installation includes a persistent background daemon called HealthMonitor.
What HealthMonitor Does: It runs continuously in the background, polling system sensors to measure memory usage, CPU load, SSD temperatures, battery cycles, and Trash size. This data feeds the CleanMyMac menu bar icon and triggers periodic notification alerts.
Under normal conditions, HealthMonitor should consume 1% to 3% CPU and roughly 80 MB to 150 MB of memory. However, three common issues frequently cause it to spiral into an infinite loop:
- Permission Timeouts & Full Disk Access Conflicts: Modern macOS requires explicit user permission for apps to inspect system files. If CleanMyMac loses Full Disk Access or encounters a permission barrier, HealthMonitor repeatedly retries the scan every few milliseconds, causing CPU usage to spike to 100%.
- APFS Snapshot & Time Machine Indexing Loops: When macOS creates local APFS snapshots or runs Time Machine backups, storage calculations change rapidly. HealthMonitor can get trapped recalculating purgeable space continuously.
-
Corrupted Preference Property Lists (plists): If CleanMyMac crashes or encounters an incomplete update, its configuration file in
~/Library/Preferences/can become corrupt, causing the background daemon to crash and relaunch in an endless loop.
Step 1: Immediate Relief (Force Quit in Activity Monitor)
If your Mac is currently overheating and you need immediate relief, you can terminate the process right now:
- Open Activity Monitor (press
Cmd + Space, type "Activity Monitor", and press Return). - Click on the CPU tab at the top.
- In the search box at the top right, type
HealthMonitor. - Click on CleanMyMac X HealthMonitor in the process list.
- Click the Stop button (the octagon with an X icon in the toolbar).
- Select Force Quit.
The Limitation: Force quitting provides instant relief, but it is only temporary. Within a few seconds or upon your next restart, macOS will quietly relaunch HealthMonitor. To stop it for good, proceed to Step 2 or Step 3 below.
Step 2: Disable HealthMonitor in CleanMyMac Settings
If you still want to keep CleanMyMac X installed for on-demand scans but want to stop the background daemon from running 24/7, you can turn it off within the application preferences:
- Open CleanMyMac X.
- In the top menu bar, click CleanMyMac X and select Settings... (or press
Cmd + ,). - Click the Menu tab at the top of the settings window.
- Toggle the main switch labeled Enable Menu to OFF.
- Click the Notifications tab and turn off all notification categories.
- Click the Protection tab and ensure real-time malware monitoring is adjusted or disabled if you rely on Apple's built-in XProtect security instead.
Disable Background Permissions in macOS System Settings
Modern macOS allows you to prevent third-party apps from running background tasks:
- Open System Settings from your Apple menu.
- Navigate to General > Login Items & Extensions.
- Scroll down to the section labeled Allow in the Background.
- Find MacPaw Inc. or CleanMyMac in the list and toggle the switch to OFF.
Step 3: Complete Removal of the Hidden Startup LaunchAgent
Many users discover that even after disabling the menu in settings, HealthMonitor continues to run or reappears after an update. This happens because the underlying startup file remains in your Library folder.
The Hidden Startup Helpers Concept: LaunchAgents are hidden background startup instructions that tell macOS: "Every time this computer logs in or wakes up, quietly start up our monitor in the background, even if the user never opened the app today."
To delete this startup instruction permanently:
- Open Finder.
- Press
Cmd + Shift + G(or click Go > Go to Folder... in the menu bar). - Paste this exact path and press Return:
~/Library/LaunchAgents - Look for these two specific files:
com.macpaw.CleanMyMac4.HealthMonitor.plistcom.macpaw.CleanMyMac4.Updater.plist
- Move both files to the Trash.
- Empty the Trash and restart your Mac.
Safe Terminal Unload (For Instant Confirmation)
You do not need to be an engineer to check this, but if you want to stop macOS from managing the job immediately without restarting, open Terminal and run:
launchctl bootout gui/$(id -u)/com.macpaw.CleanMyMac4.HealthMonitorThis safe, read-only command instructs the macOS launch subsystem to unload the HealthMonitor daemon from active memory immediately.

The Permanent Solution: Switch to a Zero-Daemon Mac Cleaner
The fundamental problem with CleanMyMac is architectural: it was designed as an always-on utility suite that insists on monitoring your computer around the clock. But cleaning disk space does not require 24/7 background surveillance.
If you want to maintain your Mac without battery drain or runaway background daemons, DiskCompanion was built with an entirely different philosophy.
DiskCompanion: Safe Mac Maintenance with Zero Background Noise
DiskCompanion was engineered from the ground up to respect your Mac's hardware resources:

Frequently Asked Questions
What is CleanMyMac HealthMonitor and why is it running?
CleanMyMac HealthMonitor is a background helper process installed alongside CleanMyMac X. It continuously tracks your Mac's available memory, drive temperature, battery health, and Trash size so it can display real-time statistics in your menu bar and trigger notification banners.
Why does CleanMyMac HealthMonitor consume high CPU in Activity Monitor?
High CPU usage (often 80% to 100% or more) occurs when HealthMonitor gets trapped in an indexing loop. This typically happens after macOS updates, when disk permission changes block access to system sensors, or when local APFS snapshots fail to calculate quickly.
Is it safe to force quit or delete CleanMyMac HealthMonitor?
Yes, it is 100% safe. Modern macOS seals all essential operating system files inside a locked, read-only system vault (the Signed System Volume). HealthMonitor is strictly a third-party helper running in user space. Quitting or removing it will not harm your Mac.
Why does CleanMyMac HealthMonitor restart after I force quit it?
CleanMyMac installs a background startup instruction file (LaunchAgent) in your user Library folder. The macOS launch subsystem (launchd) is instructed to keep HealthMonitor alive, so whenever you force quit the process, macOS automatically restarts it within seconds.
How can I monitor or clean my Mac without background daemons?
You can use DiskCompanion. Built with a strict zero-daemon architecture, DiskCompanion runs only when its window is open, uses 0% CPU and 0 MB of RAM when closed, and provides interactive visual storage exploration and safe System Data cleaning for a flat $29 lifetime license covering up to 3 personal Macs.
