I was delighted to receive notice per mail that I could finally safely use my MyPassport for Mac (WDBAAB5000ACH) after having updated to OSX Mavericks.
I was told to update SmartWare on my Mac, which I did successfully. Then I dared to connect my MyPassport, and I had to unlock the disk via the local SmartWare-application (whereas before, I had to do it via the SmartWare-application on a separate image on the MyPassport - this is not possible anymore, apparently). I immediately got the notice that I needed to update the firmware for my MyPassport, and so I tried - using the recommended WDFirmwareupdater.
However, the updater seems to get stuck at the window below. I had left in on several times, all of them at least 2 hours - no luck. What to do?
Update: Uninstalled everything, re-installed Smartware locally on my mac. The rebooted. Afterwards, started the firmware updating process. This time, I actually saw the progress bar during the updating. However, the update failed** , and my Mac is unable to see my MyPassport ever since, whatever I do.**
I guess this topic can be closed, and I’ll add my troubles to this topic.
