Unlinking dropbox from a 2014 Macbook Air

[MaryaM1]

Help! I've installed dropbox on my new Macbook Air but can't figure out how to unlink the device on my old computer. The advice given suggests I go to the security tab, which I cannot locate on my air.  I have free dropbox. What's the best way to get it off one computer without jeapordizing what is in dropbox on my newer computer?

Hey @MaryaM1, happy Monday! 

Can you try these steps, and let me know how they go? 

Open your Dropbox desktop app preferences.
Click the Account tab. 
Click Sign out. 
Click Sign out again to confirm. 

Thanks!
