in the activity monitor what is “applicationsstorageextension”?
Why is ApplicationsStorageExtension taking up so much cpu time
iMac 27″ 5K, macOS 13.7
Do you have the Setting open to calculate your Mac storage. I believe the setting for you would be at > System Settings > General > Storage. When you open this setting, applicationsstorageextension will start using CPU cycles to calculate the storage amount for all apps. Once it is done calculating the storage, then normally the process will stop using the CPU and remain idle.
If it seems stuck and fails to calculate the storage for each app, then try starting up in Safe Mode and compare the results:

If Safe Mode resolves the problem, then restart again normally to see if it comes back. If it does come back, then that would indicate you have an application that is running in the background that is conflicting with the process. The best way to determine what that could be is to post the free EtreCheck report using the Additional Text option when posting. The report contains no personal information. It may also be used to identify a hardware problem with your HD that is slowing the process down.
