- Click the Dropbox icon on the menu bar.
- Click your profile picture or initials, and select Quit Dropbox.
- Open the Terminal app (at /Applications/Utilities/Terminal).
- Copy and paste the following lines one at a time into Terminal. Press Enter after each one.
- You'll be prompted for your computer password (not your Dropbox password) after entering the first command. The password field in Terminal remains blank as you type your password. After you type it, press return.
- Important: We assume that your Dropbox folder is in the default pathway. If you placed your Dropbox folder in a custom location, replace all ~/Dropbox for the full location of your Dropbox folder. For example, if you have your Dropbox folder in the path /Volumes/DifferentPlace/Dropbox, you need to replace ~/Dropbox from the following instructions to /Volumes/DifferentPlace/Dropbox.
- Once the Terminal prompt shows up again, the instruction completed the requested task and is ready for the next command. If any of the the commands return an error or do not respond after an hour, try restarting your computer and repeating these steps.
sudo chflags -R nouchg ~/Dropbox ~/.dropbox ~/.dropbox-master sudo chown "$USER" "$HOME" sudo chown -R "$USER" ~/Dropbox ~/.dropbox sudo chmod -RN ~/.dropbox ~/Dropbox chmod -R u+rw ~/Dropbox ~/.dropbox
- Restart Dropbox by double-clicking the Dropbox icon in your Applications folder.
If this doesn't help, make sure you are using the latest version of Dropbox.
