If it is a must, how about sharing some details here ? As I just ordered a 12 inch New Macbook, I was told by the retailer that : "You need to buy another type C to type A adapter if you are accustomed to using old USB peripherals on it ! "
I am not sure what kind you have. I have noted one on Amazon but not decide to buy this version. I once booked a laptop bag from this seller.
But it will be great if your version is more attractive and happens to be a sliver-color one. I would love to take a good look at it.
At last, which platform you bought from ?
If you have the new 2015 MacBook then this cable is a must! It allows attaching USB 3.0 and older USB devices to the MacBook. At the time of posting this, there are very few devices with a USB-C connector, so this USB-C to USB 3.0 adapter is a must. I have one and I like that it's short and light. That makes throwing it in my backpack along with my MacBook without any hassle.
