Dropbox is ending support for OS X Tiger 10.4 and OS X Leopard 10.5 - why, and what can I do?

Beginning March 23rd, 2015, the Dropbox desktop client will no longer be available for download on OS X Tiger 10.4 or OS X Leopard 10.5. If you are currently running the Dropbox desktop client on these versions of OS X, you will no longer be able to sign in to your existing account or create a new account through the desktop client.

You may be signed out of your account on the desktop client as early as May 18th, 2015, and will not be able to sign in again until you update to OS X Snow Leopard 10.6 or later.

If you are signed out due to this change, please know that no changes will be made to your account. Your files and photos will be safe.

You will still be able to access your account—or create a new account—on the Dropbox website or on other compatible computers and mobile devices.

Why is this happening?

We regularly release new versions of the Dropbox application with additional features, better performance, and enhanced security, and these versions are not always compatible with older operating systems.

What should I do?

  1. Update to a newer version of OS X (Snow Leopard 10.6 or later).
  2. Access your account from the Dropbox website, or from a device with a supported operating system

I'm already running a newer version of OS X

If you received a message from us but believe you are already running a newer version of OS X, you may have your account linked to multiple computers or mobile devices. Having just one device running an older version of OS X may have triggered the email. To unlink devices that may be running older versions of OS X:

  1. Sign in to the Dropbox website
  2. Click your name in the upper right-hand corner
  3. Click Settings
  4. Select the Security tab, and scroll to find your linked devices
  5. Click the "x" beside the device you'd like to unlink
