Using Dropbox with Mac OS X Lion.

February 24, 2011

UPDATE 3 (2011-07-20):
Dropbox 1.1.35 is compatible from OS X Lion.
If you’re feeling a bit adventurous, you can use the “forums build“.

Dropbox Team Member Rian H. posted a reply assuring that the team is working to make Dropbox fully compatible with Mac OS X Lion.

“hey everyone, just wanted to give you all a heads-up that we’ll be working diligently on making dropbox 100% compatible with 10.7 over the next couple of months. stay tuned!”

Apparently the current version of Dropbox caused the Finder to crash right after login.
Apple Engineers have confirmed this and recommended Developers to wait until the issue is resolved. If you are a registered Apple Developer, head to Apple Developer Forums for the discussion.


Numbers of users are reporting they found out that would not work with Mac OS X Lion.

You can’t use this version of the application Dropbox with this version of Mac OS X.

One thread on Dropbox Forums is dedicated to this issue. Dropbox user “Filip S.” came up with a solution:

I’ve figured out a quick fix for this issue. Open Info.plist inside the application bundle, and change “Bundle Version” to 2.0 . Apparently Lion doesn’t allow applications with low bundle versions to run for some reason.

Now Dropbox v.1.0.20 works in Mac OS X Lion.

    Doesn’t seem to work with Lion Developer preview 2.
    Tried with DropBox 1.0.28. It starts at first but crashes a few seconds later.
    So, still no solution!? 😦

    So how do I access the application bundle?

      Download the latest forum build, you won’t have to change the version number.

        Thank you. I downloaded and launched the version linked and it works like a charm. No more importing my 1Password keychain from Snow Leopad every time there was a change.

    Doesn’t work for me. It says “Couldn’t start Dropbox” Then goes on to say “This is usually because of a permissions error. Errors can also be caused by your home folder being stored on a network share.” and goes on to tell me what to send to support. Anyone have any ideas? Please! Its crazy how dependent we have become on these technologies.

      Try the Forums build.

      In addition to that try deleting DropBox preferences before installing the new one.

    Thank you sooo much! Even the latest builds in the forums didn’t work for me, but this did. I’m so relieved; this was driving me crazy.
