A Microsoft file hosting and synchronization service.
I'm not sure if I want to jinx this, but I literally just disabled these extensions as you outlined in your post, and within seconds the fan on my computer slowed from jet-engine speed to mini tabletop fan. The CPU % which were spiking with OneDrive/Finder/Disnoted 100%+ almost immediately reduced to sub 20%. I'm impressed with the solve and equally nervous -
Does anyone have links to articles that explain the function of "Finder Extensions" so I can understand the consequences of disabling?
Thanks so much for all of the participation on this thread (I know I'm picking this up late!)
