Photoanalysisd is a tool that analyzes your photo collection in the background to recognize faces and millions of items in photos. It is a system application that, as the name suggests, analyzes your photographs in the background of your mac device. It appears to be attempting to identify faces for the most part. It has really changed how we Take and Share Photos



Mac photoanalysisd  was first released in macOS Sierra and High Sierra years ago, and lots of people complained about how much CPU it used. Some users, particularly those on macOS Catalina and Big Sur, are still experiencing issues.

What is photoanalysisd How does it Work?

Photoanalysisd it’s a sophisticated procedure that uses face and object detection technology. This process is a one-time thing except a new  photo is added. Majority of mac users has complained that it consumes up to 80% of their CPU when they buy a new Mac device. After it has completed its analysis, you will be able to use your library in a more advanced manner. So it’s beneficial for the user experience, but it might pose problems in other circumstances, such as high CPU utilization, which can lead to constantly running fans.

When Is Photoanalysisd Process Said To a Problem?

Photoanalysis is said to be a problem when the subject of the photo is unclear, or when the image has been altered in some way, or when you have a lot of photographs saved in the Photos App.

If you have a large number of photos to analyze for instance, the Photoanalysisd process may take several days. Assuming your device contains around 500 photos, Photoanalysisd will take less time to analyze them,  ( it can be done in less than a week, but if it has over a thousand photos, lets say 2000 for instance, it would take a longer period running into weeks.

Here are a few things you should know about the Photoanalysisd process ; the process is paused when you open the Photos app on your Mac device. The Photoanalysisd process restarts when you minimize or close the Photos app, and when your device isn’t connected to power, this process also pauses.

There are a few cases where you are required to kill the photoanalysisd process. An example can be if during the time of photoanalysisd process, you have an urgent need to use other resource-intensive programs for 3D Designing and Modelling like 4K Video Editing, playing high-end games, or any other gaming activity that requires high CPU usage, you might consider disabling Photoanalysisd either temporarily or permanently.

You might as well consider disabling the photoanalysisd process if it is making your system slow during a high-end task.

3.  Go to the search bar and type  Photoanalysisd.

4. Select Photoanalysisd from the search result by clicking on it. Next, click on (X) symbol representing Stop button located at the top, left of the (I) button is the Stop button.

5. To temporarily disable the Photoanalysisd process, click the Force Stop button.

2) Add Names to Pictures Manually

The type of images in your library determines the validity of this method. If you have a lot of pictures of yourself and other people then you have a high success rate, but if your photo library is filled with lots lot of abstract pictures, then you wont see much difference with this approach.



Naming your pictures manually reduces the CPU consumption of the Photoanalysisd process. To do so simply follow the steps listed below;

1. Go to the Photos app on your Mac, and open it.

2. Select the image you want name and double-click on it.

3. On the left side of the Share button locate the “i” button in the toolbar, and click on it.

launchctl disable gui/$UID/com.apple.photoanalysisd && launchctl kill -TERM gui/$UID/com.apple.photoanalysisd

The next step is to disable the Photoanalysisd process. This can be done by running the command below;

launchctl disable user/$UID/com.apple.photoanalysisd && launchctl kill -TERM user/$UID/com.apple.photoanalysisd



If the above  commands fails, you can use any of the ones listed below; 

sudo launchctl remove com.apple.photoanalysisd


launchctl unload -w/System/Library/LaunchAgents/com.apple.photoanalysisd.plist

To re-enable the photoanalysisd service use the command below:

launchctl load -w /System/Library/LaunchAgents/com.apple.photoanalysisd.plist

4) Disable Photoanalysisd in macOS Catalina

This step is for those that have Catalina OS  installed on their MacBook or iMac, follow the steps below to disable Photoanalysisd.
Open the Photos app on your phone
Select Photos Preferences from the Photos app’s top toolbar menu.

Photoanalysisd Stuck

With the rising popularity of social media, it has become more and more difficult to manage all the photos that are uploaded on various social media platforms. The photo analysis tool is a great solution for this problem because it helps users organize their photos and delete unwanted ones.

The photo analysis tool can be used by both individuals and companies. Individuals can use the photo analysis tool to sort through their personal photos and delete those that are too old or have been uploaded too many times. Companies can use the photo analysis tool to make sure they have the right number of images on their website or to check if there are any duplicate images in their database.

When Photoanalysisd becomes stuck it signifies that the process needs enough memory, problem, and when this happens, it will become unresponsive.
Another reason for this process’s inactivity is if it’s waiting to read disk block or network data block. This process will become blocked if 
the data cannot be read.
To prevent Photoanalysisd from becoming stuck, you’ll need to Force Quit the program. By following the methods outlined in the preceding 
section, you can Force Quit this process. You can restart this procedure after Force Quitting it to see if it’s operating properly.
This fix is compatible with Sierra, Big Sur, High Sierra, and Mac OS Catalina.

Photoanalysisd Kernel Panic on Mac

The kernel panic is a state in which the kernel is not executing instructions. When the kernel is not executing instructions, it will enter a state of panic. A panic can happen when there are too many processes running at the same time and there isn’t enough memory to execute them all.



This Kernel Panic condition caused by Photoanalysisd can occur if the Photoanalysisd process or the Photos app are both malfunctioning.

If the Photoanalysisd process causes your Mac to restart abruptly, you’ll get a Kernel Panic error, with the phrase “your computer restarted because of a problem.”

You can Force Stop the photoanalysisd process and update the Photos app to the latest version, in other to fix this issue.
