High CPU consumption for Mac OS Photos app processes photolibraryd and photoanalysisd

Hello Andre_Seattle,

Once the libraries are analyzed, there should not be a reason for a lot of CPU usage until more photos are added.

We would suggest starting up the system in what is called safe mode to see if a reason for these process running can be found. Safe mode only loads what is needed to run the computer. This can help isolate what is causing issues.

To start in safe mode, follow these steps:

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.

2. Release the key when you see the login window, then log in to your Mac. 

3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.

The computer will take longer to start in safe mode, and the screen may have some distorted video as it starts up. This is normal. Once you are logged in, use the system and test to see if the issue continues.

If everything seems to work as expected, go ahead and restart the computer normally and test again. There are steps outlined on what to do if the issue does or does not continue in safe mode.

Starting in safe mode also forces the computer to run some disk checks similar to First Aid. This can actually resolve some issues.

Have a good day.
