    Can anyone recommend either an HDMI or mini-DP adapter for the 2017 rMB that actually works?

    I have tried two now (from Cable Matters and Uptab) and neither one works at all (doesn't even wake up the monitor) with my rMB. The CM one works fine with a coworker's machine (haven't tried the Uptab one). This is happening with multiple displays and they are 1920x1080 so 4k issues are not relevant.

    Is the only option the Apple adapter?

    What is so special about the rMB that prevents adapters from working properly with it?

    The rMB is USB 3, not thunderbolt, that might be something to keep in mind.

    Do you need something portable, or do you prefer something more "docky" for office use?

    I currently use this one https://www.amazon.com/gp/product/B01FWT7MEA and it works fine.
    It's more portable kind and it has a bunch of other I/O (1gbit ethernet, hdmi, usb3, sdcard, usb power passthrough).

    The only thing I can ding it for is that it gets kinda hot with use.

    I would look at the OWC Usb-C dock if you don't require portability and want something that's self powered.

    Yep, I'm aware that the rMB does not support TB. These are all "standard" USB-C / 3.0 adapters that I've been trying that claim compatibility with the rMB.

    I need something small and portable. I'd be carrying it around with me to connect to projectors / TVs to do presentations.

    I bought the Plugable USBC to HDMI dongle. It is confirmed to work with the 2015 and 2016 MB.

    Guess what? It doesn't work with the 2017 MB. They have since confirmed it does not work with the 2017 MBP or 2017 iMac either. Something has changed with Apple's implementation of USBC in the 2017 models.

    Plugable has since confirmed the USBC to HDMI cable (not dongle) does work though, including with the 2017 models, but I didn't actually want the cable.


    I have a USBC to Mini-DisplayPort dongle and a USBC to DisplayPort dongle on order from elsewhere so I'll keep you posted on that.

    Here is my post about it in the dongle thread.

    I just bought the Apple HDMI adapter tonight. I'll see how it works out tomorrow. I figured I would stop messing around with 3rd party accessories and this one will let me charge the machine while I'm using it which seems like a plus if I'm presenting for a long time.

    The Apple HDMI adapter does indeed work. As soon as I plugged it in it downloaded some kind of (firmware?) update that required a full reboot of the machine.

    Tried the other two adapters after the update but they still do not work.

    At least I know the machine isn't broken, but I would really like something in the Uptab form factor (aluminum and relatively small) -- the Apple one is kind of clownish.

    I guess I will contact the manufacturers to see what they say.

    Did you get 60Hz with the apple one? I cannot. Also any update on the CM one? Thanks.
