I recently updated to Catalina on my MacBook Air, and after doing so Photos spent about 5-6 days analyzing my pictures. After it finally finished, I noticed my machine was still lagging like mad. A quick look at activity monitor shows mediaanalysisd is at fault. I understand this is Photos analyzing faces in my pictures, but it seems to be doing this endlessly.
I tried the solution found in this topic https://discussions.apple.com/thread/8354929
but that doesn't seem to work for Catalina as I cannot delete the .plist in LaunchAgents even with SIP disabled.
Any updated ideas/fixes for this?
