How Dropbox Hacks Your Mac

It looks like in 10.12 Apple has added TCC.db to SIP, so this will no longer work — Dropbox will, hopefully, actually be forced to request accessibility access like they're supposed to. I'm sure they'll still demand your admin password via a dialog that tries super hard to look like a system one to use for whatever other more or less nefarious purposes. Would be nice if there was an alternative that actually syncs as reliably and performantly, but in my testing that's very much not the case.

I appreciate the trend of Apple forcing Dropbox to stop doing dumb shit, though. (Previously, of course, the SIMBL-style Finder hacking)

I use owncloud (and then dropbox inside it so some files are double backed up). I find it to be just fine. Have you had any problems with it?

Yes, last time I tried it, had a variety of conflict issues plus the client had some problems, performance and otherwise. If you're just using it as a backup solution (does it even keep file history?) from a single machine + mobile/web access, it may well work acceptably.
