Getting Dropbox back in my Finder Favorites after upgrading my Mac software

I found the explanation here very helpful and resolved my issue in seconds. Thanks so much.

Helpful information and resolved my issue....key is to find the DB folder not the application icon. Thanks!!!

Very helpful and, I thought, very clear.  Thanks so much!

For those who have "lost" their dropbox folder, just use the spotlight search (i.e. the magnifying glass icon at the right hand side of the bar at the top of your screen) to search "dropbox" and your dropbox folder will show up in the finder.  You can drag and drop it from there.

The solution worked for me. I upgraded to El Capitan a few days ago. I just fixed it using Robert's solution. First, the problem may be you are not noticing that the Dropbox icon is now at the top of the finder window to the left of the search bar after the upgrade. I personally didn't want it there. So I did a search for "Dropbox", my Dropbox folder came up and I dragged it onto the sidebar. To be sure, I closed Finder and it was still there.

I've read the thread carefully, viewed Robert S.'s youtube video but still need help:  I have two dropbox accounts.  One shows up in the left hand finder window.  The other used to but doesn't any longer.  How do I download that account so it shows up on my computer and can therefore be dragged over to the left hand finder menu?  Right now it doesn't show up on my computer, although if I open a file through say MS Word, and do SAVE AS, I can see the account and save docs to it.  Thanks in advance.

Dear all, I kept digging and found this response from Maria Elena P. in a different thread.  The issue was that I didn't have all the options checked off on Finder>Preferences>Sidebar.  Once I checked them all, I was able to see the second dropbox account and drag and drop it per Robert S. instructions.  Thanks all.
