My Passport Edge for Mac - software updates don't take

I just bought this Passpoert Edge for Mac.  On setting it up, the system says there is a more recent versdion of the software utilities.  When I do the update, a .zip file downloads and then a window pops up saying “Updating Software”.

However, the system then loops back to telling me there’s a later version.  This loop can’t be broken when trying to update.   Any help welcome.  This also happens when I try to use the WD Security app.  Same thing - loops.  Is this because the app on the drive doesn’t update?  I found that the Utilities app in my Applications folder did update.

Hi, you can also try updating the firmware to the latest version.
