I installed Dropbox 1.6.16 and am running OS 10.7.5 (Lion). I continue to get this message and don't know how to fix:

Couldn't start Dropbox

This is usually because of permissions error. Errors can also be caused by your home folder being stored on a network share.

I am the only person using this Mac and I don't have a network so this message doesn't make sense to me.

How can I get Dropbox to work for me?

It turns out that Dropbox has a hidden feature to fix such things. Open the Dropbox preferences, click on Account, then press the Option key. The Unlink This Computer button will change to Fix Permissions. Click that button and let Dropbox go through your files.

The problem is Dropbox won't start, yet your solution requires that you start Dropbox? How did this get upvoted? –  scaba Nov 18 at 22:42

Are you an administrator? If you are, try Chown and Chmod

Type the following into Terminal:

sudo chown -R yourUsername /Users/yourusername/Dropbox

sudo chmod -R 700 /Users/yourusername/Dropbox

If that doesn't work I'd run diskutil repairPermissions /

If those don't work, I would reinstall Dropbox.

Try starting Dropbox using the command line.

  • Open Terminal (search for 'Terminal' in Spotlight).
  • Type cd /Applications/Dropbox.app/Contents/MacOS then press Return.
  • Type ./Dropbox then press Return.
  • Report back with any error messages.

If you want to try something else while you are waiting for us to get back to you, repeat the above commands, with the exception of open Dropbox. Instead, continue on with the following steps:

  • Type cd /Applications/Dropbox.app/Contents/MacOS/. (Just press Return at the end of every command...)
  • Type ls -la. You should see four records. We are interested in the bottom two. To the left of "Dropbox" and "python", you should see -rwxr-xr-x. These are the permissions for the files. If the pattern you see doesn't match what I have posted here, there is a problem with the permissions. (If so, report back here for the next step. If not, keep going through this list.)
  • If the permissions were fine in the previous step, we can check a few other places. Type cd ../ to return to the above directory.
  • Type cd Frameworks.
  • Type ls -la. The top two files (with actual names) should have the permissions drwxr-xr-x. The bottom three files should have the permissions -rwxr-xr-x. (Report back if they are different.)
  • Type cd ../ again.
  • Type ls -la. The permissions this time shouldn't make much difference to the app, but we may as well check them. They should be as follows:

    
    drwxr-xr-x   9 user  admin   306 30 Jan 12:59 .
    drwxr-xr-x@  3 user  admin   102 30 Jan 12:59 ..
    lrwxr-xr-x   1 user  admin    28 30 Jan 12:59 CodeResources -> _CodeSignature/CodeResources
    drwxr-xr-x   7 user  admin   238 30 Jan 12:59 Frameworks
    -rw-r--r--   1 user  admin  2647 21 Jan 09:09 Info.plist
    drwxr-xr-x   4 user  admin   136 21 Jan 09:09 MacOS
    -rw-r--r--   1 user  admin     8 21 Jan 09:09 PkgInfo
    drwxr-xr-x  74 user  admin  2516 21 Jan 09:09 Resources
    drwxr-xr-x   3 user  admin   102 21 Jan 09:09 _CodeSignature
    
  • Once again, if you notice any of the permissions are different, let me know which ones are different, and I will give you detailed instructions on how to change them.

Have you tried any of the following?

  1. Reinstall Dropbox.
  2. Repair Permissions
  3. Create a new user on your computer and try dropbox from there?

Otherwise a closer inspection to the System.log might help.

All you have to do is:

  1. Unlock home user
  2. Right click on home user name and click on Get info
  3. Go to General and un-tick Locked
  4. Hope your dropbox work as usual

I had same problem. This helped me to fix issue:

Remove hidden dropbox folder '.dropbox' in user's root folder (Users/YourUsername/.dropbox)

You can do it by running this command in terminal:

sudo rm -r .dropbox

Then simply erase everything what is left in Applications folder and make a fresh install.

I found this solution here: https://discussions.apple.com/thread/6318381
