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?
Thanks, but that's too much for me. It's strange that they are not trying to solve this. I was hoping the recent Mojave update would fix this, but wasn't the case. Two such companies that big, you'd think they would have the capacity for solving such bugs.
One computer has the old version of dropbox and one has the latest stable version and same problem with both. You, Dropbox, really need to do something to check what the problem is with your software and Mojave not keeping asking users to do stuff that doesn't help.
I have a Macbook laptop and iMac desktop both not syncing after Mojave upgrade. I did all the usual troubleshooting...quitting dropbox, deleting dropbox, reinstalling newest version, etc. None of that worked. These are the things the dropbox technical person recommended. However, it is clearly some glitch in the Dropbox software related to working with Mojave not my computers. One of my computers deleted the 770,000+ files I have in my Dropbox and then started "syncing" and reinstalling them after I installed new Dropbox software. After "syncing" for days, Dropbox is now working on my desktop but my laptop is still "syncing" the 770,000+ which really means redownloading everything. Presumably when it finishes it will be OK.
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"
I have a 2016 MacBook Pro that's running 10.14.1 and Dropbox 61.4.95 without problem. But my 2014 Mac Mini booted from an external SSD crashes when Dropbox is running. The machines gets slower and slower, beachballs, and eventually hard crashes by shutting itself down.
having this EXACT problem! Disabled Early Releases and keep reinstalling the stable .4 release, but then even though early releases is disabled, it keeps reinstalling 64.3.121 which then causes the same sync'ing forever behavior. This has been going on for 2 WEEKS and I can't even sync with my business team or partners... nightmare.
