Something called DevonthinkHelper64 keeps using over 95% of my CPU. What is it and is it necessary? Is there any way to disable it?
It’s a background task of DEVONthink used for certain operations, e.g. indexing. It’s necessary to avoid that buggy code of macOS or of third-party extensions can crash DEVONthink. Most of the time this task should be idle. Did you perform any larger operations, e.g. import/index a lot of files?
