Dropbox keeps "re-syncing" and hogging my CPU

Level 4

The fan just kicked on in my 2018 MacBook Pro, which is unusual, so I opened Activity Monitor. Dropbox is using 148% of CPU. I clicked on the Dropbox icon in the menubar and it says it's "syncing 53,461 files". 

This happened just a few days ago as well.

I'm not sure why, but I seem to recall that in both cases I had used CleanMyMac X just before the sync was triggered. I don't know how or why that would be connected, because that program is just removing old files that aren't used anymore (not in Dropbox). 

Any ideas?

@Chris K.86,

 

I have heard nothing but terrible things from CleanMyMac X. Typically, Macs take care of themselves. If you used it, Dropbox might be set to sync some folder that CleanMyMac messed with. I would do this.

  1. Shut down Mac completely.
  2. Wait a few moments, then turn it back on.
  3. Make sure Dropbox starts syncing (just check and see if it is active).
  4. Check CPU usage.

My guess is that CleanMyMac is messing with something DB is syncing, which causes it to slow down.

Thanks. I'll try uninstalling it and see what happens.

I always like CleanMyMac X because it does all that I requires. It can uninstall all the additional application and delete all the dump file to tweak the Mac.
