There's really no way around it. Apple has serious port problems. With iPhone 7, it removed the headphone jack, much to the sound of audio files. The newly announced MacBook Pro has a huge six USB Type-C ports. It's great! But it's all the ports it has. It's not that good!
The USB Type-C standard has gained ground in recent years as computers and mobile devices adopt it. Now, most Android phones come with this port standard, instead of the older microUSB. USB Type-C is a clear improvement because the plug is reversible, it's faster, provides more power, and can output almost any kind of signal. In the future where all your peripherals are Type-C, it will be useful. Right now, it means you need many adapters. It only happens, Apple sells these adapters.
The outbreak was fast after the new MacBook was put on sale. Apple killed all the dongles, but it has now dropped and lowered prices. Some of Apple's first-party adapters have seen a drop in prices as high as 50%. For example, the default Type-C for Type-A dongle (the old USB you are familiar with) is down to only $ 9 now. Most third party accessories Apple sells is at least 25% off as well. This makes the situation much less aggravating for new MacBook buyers.
In addition to the decline in the dongle price, Apple is lower prices for all USB Type-C and Thunderbolt peripherals by 25% through the end of the year. It includes products like 4K and 5K LG monitors and external card readers powered by Type-C.
