The app re-indexes all files after each restart on Mac.

I switched back to Mac this week after three years on PC. I bought a new MacBook Pro and installed the latest Dropbox. After a few days I managed to sync my almost 2TB of files to the new computer. Each day when I start the computer, indexing takes over three hours and syncing what is already synced adds to that time. I have Dropbox located on an external SanDisk Pro Blade Thunderbolt 3 NVME.

I see, thanks for keeping me in the loop on this craigsfowler​ - much appreciated.

If this becomes too much of an issue in the future, please feel free to reach out and we'll take it from there.

Thanks for asking ... This issue has mitigated somewhat for me.  I've made many dropbox folders cloud only and also upgraded to MacOs Sequoia 15.5 .  I still see re-indexing after reboot but, at most, for about 15 minutes.

Hey Jack D-77​ - thanks for flagging this with us. I've just followed up via email to have a further look internally with account and device specific information, so please take a look at your inbox and we'll take it from there. 

While we're at it, I'm sorry for the late response here, but are you still having issues with this too craigsfowler​?

I just upgraded to a Mac Studio M3 ultra, running Sequoia 15.5. My Dropbox folder is located on an external drive as well, running v227.4.4774. It takes over 8 hours to re-index all my files after a computer shut down. 

As I work directly from dropbox folder, this makes me feel very apprehensive about beginning to work on my files. As it's indexing, would there be a conflict between the live changes I make to the file while dropbox is re-indexing all my files? I have shared folders with other colleagues (they own the shared folder) - could this potentially alter their original files as well? 

Thanks for that, Anya.

Have you reached out to our support team about this yet?

Hey anyajohnston, sorry to hear that.

Can you give us some more info?

Which version of macOS and which version of Dropbox are you using? You can see the latter by hovering over the Dropbox icon in your menu bar.

same problem please help, means i cant open any files on my computer for like an hour 💀💀

I have enough space:

I don't use a proxy, VPN, antivirus, or any security software. The MacOS firewall is disabled.

In regards to the domains: that is a *very* long list and I don't have the time to test it. I'm not even sure what would be the best way (through the browser??). But I can tell you I have never added any domain to be blocked by my router, nor have I ever called my ISP to block something.

Also, note that the indexing eventually finishes, and Dropbox works fine. I think I'd get an error, or things wouldn't sync, if a relevant domain was being blocked.

Finally, a completely separate issue: I've had to restart writing this response 4 times now (had to switch to something else) because this box has a problem: all of a sudden it clears everything and somehow moves me to another reply box, and all my initial content is lost. It may have something to do with having a picture mixed in - not sure. But please fix it, it makes it very difficult to reply.
