You likely won't be able to change this behavior as Apple is all in with cloud syncing of data and even if you neutered the processes on this version of 10.12, the next security update or patch will likely re-enable this behavior. If you need backup, you can script that and store just the periodic backups in dropbox. There are several daemons that run in the background so you'll want to store your these files in a directory where dropbox doesn't perform any syncronizioaion. This is the design of iCloud based photo library storage. * Note: I am aware of the hazards of using Dropbox to sync a Photos library. This is irritating, because neither my computer nor my internet connection is very fast, so it slows my work down. Is there some kind of background process that is accessing or modifying my Photos library? I tried shutting off iCloud on my laptop, but it had no effect on the problem. This occurs despite not having the Photos app open, and not intentionally doing anything related to the Photos library! I think they have something to do with the database that the Photos app keeps to organize the library. The Dropbox widget notifies me when files have been changed, and it is syncing those changes.įrequently throughout the day (3-4 times, as far as I can tell), the Dropbox widget indicates that it is syncing a bunch of files that, I think, are part of the Photos library, like this:

I currently use Dropbox to sync, among other things, my Photos library on my laptop*.
