Cannot start Dropbox app on Macbook

Sure!

Hi

I have 5 x macbook pro 2012 running on opencore. 2 x OS 12 and 3 x OS 13.. When reloading. load with the first edition Os 12 ..e.g 12.1.. then add your DB app (on line only) this should add it to you application folder-- let it sync and do its thing. then update your OS e.g- 12.1 to 12.3. once updated. let DB update itself or ask you to update. your DB folder should move to your CloudStorage Folder.. Let it sync and do its thing again.. be patient...... Then if you need, you can set your DB to off-line  and add all your folders - if you work DB off line...  3 of my Pro's updated with no problems at all.... 2 ,  I had to reload the software to get DB working again...

Hi al f., I just sent you an email. 

Reply back to me, and we'll take it from there. Cheers!

Hi Megan, I'll get to that email ASAP this weekend to try to fix my DB issue once and for all. 

Thx

I was able to solve this on my own. I have no idea if this is the 'officially sanctioned' approach but here is what I did:

** OBLIGATORY WARNING ** This is what I DID. YOU should do your own research and make the best choice for YOUR needs. You should also listen to Dropbox support, not some idiot on the internet. I am not suggesting or advising to try to do this. I am a software engineer with 25 years of experience so this kind of thing is second-nature to me. In other words, I am a professional. If you are not a professional, use at your own risk.

1.  Make a backup of the hidden Dropbox data folder ( yours is at `/Users/YOUR_USER_NAME/.dropbox`). If you are comfortable using the command line (Terminal) you can run `cp -R /Users/YOUR_USER_NAME/.dropbox ~/Downloads/dropbox-data-backup`
2. Then run `rm -R -f /Users/YOUR_USER_NAME/.dropbox`
3. Quit the Dropbox app and relaunch it
4. It will think it is a new install (technically it is)
5. Follow the prompts to set up your Dropbox again. You will have to choose which folders to sync again and let it sync, THEN go through the Mac OS update ther integrates Dropbox with the Finder but for me that was prefarable to waiting on Dropbox support to respond and jumping through a bunch of hoops to probably end up doing something similar.

Hi! I'm running into the same issue as well and have tried all of the steps in this thread to troubleshoot this issue. I have updated to MacOS Ventura 13.4.1 (22F82). The grey Dropbox Icon no longer pops-up on my menu bar and, while the folder shows up in my finder window, none of my files are syncing and cannot be opened from the folder. I keep getting this same error message with the following text file (see below).

Any help would be greatly appreciated! Please send me an email with directions.

Thanks for bringing this to our attention, jcyc1.

Can we send you an email, so we can look further into this?

Yes please send me an email! 

Hey jcyc1! Please reply back to my email, when you get the chance. 

Cheers.

Hi Nancy, 

I did not receive an email from you -- I did receive a link to a ticket being open but when I clicked on the link it just brings me to this page: https://www.dropbox.com/support/

Please advise on what to do!

Joey
