Everything wrong with Apple’s Dongles
Apple has removed the headphone jack from the iPhone and their MacBook laptops are USB-C only. You can’t even plug your iPhone into your MacBook without an adapter. Apple makes over 20 different types of dongles. You need an adapter or a dongle to connect to things like HDMI, ethernet, or wired headphones. Apple getting rid of the headphone jack and other ports has caused a lot of fragmentation.
