If you are experiencing high CPU usage on macOS, there is a good chance that “Suggestd” is the cause. This service, which is used to make it easier for users to type by providing word suggestions as they type, can be a bit of a resource hog.
Suggestd is a process that macOS uses to suggest words when typing. It’s located in the Activity Monitor application under the name “suggestd.”
While this item is helpful, it’s infamous for using an unusually high amount of CPU (sometimes up to 200%). Suggestd has caused my Macbook Pro to get extremely hot, and everything starts running very slow.
