So now we need dongles for dongles. Let it be noted that these are all solutions to problems that Apple chose to create.
I have a similar dongle for my all USB-C MacBook Pro. It wriggles like crazy. The amount of large file transfers failed due to moving the laptop slightly to one side or reaching out and accidentally touching the cable is annoyingly staggering. If you have an all USB-C Mac, invest in a hub that connects with a wire, not one that sits firmly on one side. You'll have a more reliable setup. However, stable or not, sometimes when connecting a USB/3 drive, my wireless connection will erratically drop until I disconnect the dongle. It's really touch and (no) go. Thank you Apple. I know, "It's your fault for getting a ****** dongle. Serves you right for being stingy on good accessories," some of you might want to say, only that the dongle was actually a rather expensive one, had good reviews and was not advertised as "******," otherwise I'd not buy it in the first place. You only find out when it's too late, usually when it's too late to return the dongle or the Mac. Once upon a time, there was a laptop that you took out of the box, and "it just worked." Alas, many believe nowadays that this was just a myth. Again, thank you Apple.
Luckily for me, I got my old MacBook Retina 13" model with integrated USB-3 ports and HDMI and additional storage expansion though a nifty drive repaired and working again. I'm keeping this baby until one of us drops dead (I still prefer it to be my Mac, for all the love I feel towards it). I just hope I can find a sucker to buy my "New" MacBook Pro 13. Should't be too hard, after all, it's newer, thinner and shinier. After all, I got doped into being it, and I'm not the dumbest kid on the block. It's hardly been used at all (as soon as I got my old Mac repaired, I preferred using it instead). I'll even throw the dongle and the MagSafe workaround cable into the mix for free (yeah, workaround is the name of the game with the new generation). Be my guest.
