Dropbox Issues with Mac OS Mojave
Users on Mac OS Mojave are experiencing an issue with Dropbox, their computers have become extremely slow. It works fine when Dropbox is not running.
When Dropbox app is relaunched, it takes about 30 minutes then it tries to sync files and that never stops.
Is anyone else experiencing this issue? Does anyone know how we fix this?
THANK YOU, firstlooks!
Your instructions finally worked, whereas everything else had failed. More detailed instructions for deleting the hidden folder can be found here:
Under Mojave, dropbox renders my computer unusable after about 10 minutes. It looks like the problem is I/O requests—either too many of them building up or somehow each one of them taking too long, but if I leave dropbox on, my laptop becomes completely unusable. If I turn off Dropbox, the computer recovers quite quickly. I have a lot of files on Dropbox, and use selective sync to turn them off. I here's hoping somewhat at Dropbox is paying attention to this.
Seems that Dropbox and Mojave are not compatible. It was a very painful 2 days of wasted time realsing this to be the case! - And strange that this is not flagged by Dropbox or Apple with some kind of warning not to upgrade to Mojave.
Mojave+Dropbox=crippled computer :(
Well, this isn't great, but it makes my computer usable again...I pieced together a command line that lowers dropbox's disk and cpu priority to the lowest setting. I can now print again in Mojave and use things that rely on dropbox folders. Somehow the I/O is getting queued in such a way that there's a huge backlog and it causes memory and cpu resource crunch. This seems to fix it for now:
sudo pgrep "Dropbox" | while read line; do sudo renice 20 -p $line ; done
what it does is "renices" all the dropbox processes to the lowest priority. It seems like doing this, and then rebuilding my metadata database with a
sudo mdutil -i on /
has made the problem better. YMMV. You will have to run the first command with each reboot. Hopefully that helps someone?

I installed Mojave on my iMac a few weeks back and everything worked perfectly excpet Dropbox which completely killed my machine. As werun our entire business through Dropbox, I had to go through an extremely painful 3 day process to revert the machine to High Sierra which is now running perfectly. Too scared to try Mojave again. Couldn't find anything online about similar issues at the time, but what you're descibing is exactly what happend to me. I'm afraid I don't have a solution otehr tjan to uninstall and revert back - itself a very complicated process.
I have the same problem: Can you estimate whether you will find a solution, and how soon, or do we have to switch back to Sierra? Hopefully you can do something about this, because otherwise Mojave is working very well!
I am experience slowness with Mojave on everything. I have no tips for helping... nothing I have tried has yet worked. Now that I have Dropbox reinstalled (I had to completely wipe my hard drive), I have kept local files to a minimum, so slowness is only affecting files I need to open that I left resident on the "cloud"
Apparently my problem was not with Mojave or its ability to work with dropbox. After having a specialist analyze my iMac, I found that the problem was my hard drive that was slowly failing. It must have coincidental with the installation of Mojave. Subesquently, I switched to a solid state drive and everything is working fine, compatibly and fast.
brand new, literally 2 days old, iMac PRO here. As soon as I put dropbox on the machine; everything came to a screetching halt. This even happened on my old iMac 13,2. I've been beating my head against the wall on this issue and when i got the new machine, the answer became quickly obvious as it was one of the first things I installed after running all system updates.
This is a DropBox software incompatability. Only solution is not even installing the desktop app until it is fixed, which is a massive setback in my workflow.
Yes, and what's worse is that DropBox support is either completely in denial about it or stalling.. or ignoring the issue. This has been going on for a month for us, totally shutting down my ability to work or keep in sync with my team at the office, and my reward for weeks of an open tech support ticket has been useless emails telling me my DropBox has a lot of files in it (yeah, no kidding, and it's been working fine like that for 4 years or more) or instructions to do things I already told them I've done multiple times.
In case it helps anyone, one thing that worked on one of my Macs running Mojave but not the 2nd one I have was to completely start from scratch and NOT try to preserve my existing sync'd DropBox folder (which I could only do b/c I hadn't recently updated files on that machine). Then when I re-synced to my account I chose online-only instead of local file sync'ing, and that has so far been working. However, doing the same thing on a 2nd Mac (at work) didn't work and it's still doing the sync'ing forever thing and I have 100's of un-sync'd files as a result. So yeah, good luck with that but maybe you'll get lucky.....
Oh, and the other joyous thing we've run into is that even when the "be part of the beta program/early updates" thing is unchecked in our account, DropBox STILL updates us to a beta .3 version (.4 is the stable version for any build series FYI) every time, meaning we can never really test a previous stable .4 version. Fun fun fun.
DropBox, you guys need to fix this madness or you're going to lose a lot of Mac-based customers. This has been terribly handled across the board and it's causing a lot of lost productivity.
y Same problem here. Dropbox works perfectly in High Sierra, stalls at Checking for changes under Mojave. Tried unlinking and relinking, reinstalling, renicing, disabling/enabling LAN sync, etc. No joy anywhere.
I am. I have an old macair running high sierra. Boom -really quick. I don't synchronise all the files on that.
My i-mac -late 2015 tear-your-hair-out- slow! Awful!!!

same problem here: since on macOS Mojave 10.4 the Dropbox app is stuck on "connecting" and won't sync my 1Password folder with other Apple devices (they perfectly sync between them, only the iMac won't). This is a BIG problem as you can imagine.
I have Dropbox and Mojave installed on 3 computers - iMac 2013, MacBook Pro 2014 and MacBook Air 2013 and I haven't had any problem with DropBox and Mac OS Mojave on either one of them.
