Users of ExpanDrive v5.1.3 on OS X El Capitan will need to manually upgrade to a newer version of ExpanDrive by downloading it at www.expandrive.com. ExpanDrive v5.1.3 on OS X 10.11 exhibits a broken auto-updater. Make sure to quit ExpanDrive if you’re already running it. This release was only available for about half a day, so hopefully it doesn’t affect too many users. ExpanDrive v5.1.4 is already available with a fix. Our apologies for the trouble.
