Q: USB-C Multiport Adapter update not installing

I thought I had the answer to this but ...

 

I installed the USB-C software update soon after it was released. It reported "Installation successful" but every time I booted the rMB there was a notification to install the update. A check of the version  ( About the USB-C Multiport Adapter Update 1.0 - Apple Support ) revealed it had not updated.

 

I finally read the instructions on the splash screen during installation and realised that the adapter needed to be plugged in and connected to a power supply. I did this and tried installation again but still got the splash screen. I tried the installation a second time and it has finally worked.

iMac (27-inch, Late 2012), OS X Yosemite (10.10.4)

    Hi there Michael Paine,

     

    It sounds like the USB-C update appeared to install but you still have the prompts to update it, and it did not actually install. I would start by booting to safe mode.  This will clear some system level caches and perform a disk check and repair if needed. 

     

    Follow these steps to start up into safe mode.

    1. Start or restart your Mac. 
    2. Immediately after you hear the startup sound, press and hold the Shift key.
    3. Release the Shift key when you see the Apple logo appear on the screen.

    After the Apple logo appears, it might take longer than usual to reach the login screen or your desktop. This is because your Mac performs a directory check of your startup disk as part of safe mode.

    To leave safe mode, restart your computer without pressing any keys during startup.

    From: Try safe mode if your Mac doesn't finish starting up

     

    Then leave safe mode with a normal restart and check to see if the driver is still installed, or if you can then install it again properly. If not you may need to try resetting the PRAM and testing again:

    If it still is not resolved then I would next reset your SMC and give it another go:

    Thank you for using Apple Support Communities, all the best!

    THanks for the tips. I did get it to install eventually. I wanted to alert people to the need to have the adapter and power connected.

    I have this same problem with my Macbook that I just bought about a week ago. I tried all the steps you mentioned but I still get the prompt to update the USB-C Multiport Adapter. Any other ideas?

     

    UPDATE: I got to work finally. Apparently if the power to the Mac is below a certain threshold, it won't install. I plugged my Macbook into a different outlet and it installed successfully. The original outlet I used is known to have unstable power output (sometimes lights dim/fluctuate, etc.). Hope this helps anyone else with this problem.

     

    Thanks!

    I tried the NVRAM reset but that didn't work. So then I worked through all the pre-steps to the SMC Reset and tired again without doing the SMC reset and it worked. The only thing I can think of is the Force Close showed Spotify was open. So after the final shutdown I unplugged the adaptor, put the mains cable directly into the macbook and restarted. Once it was up I closed Spotify so the only app showing as open was Finder. I then plugged-in the adaptor (connected to the mains cable) and installed from the prompts. This worked.

    I also had the problem of updating the multiport adaptor.

     

    I was using a 3rd party power adaptor (Anker). After reading this thread I switched back to the original Apple USB-C adaptor (and cable) that came with the machine and updated the multipart adaptor. It worked properly afterwards.

     

    Hope this helps.
