USB-C, like any other port relies on a protocol. They add additional connectivity to the existing USB-C ports – like HDMI ports, gigabit ethernet (via a gigabit ethernet port), and even standard USB-A ports. This allowed Apple to simplify the design, while still allowing all the connectivity of older MacBooks – but with one major caveat: adapters. These are more versatile than USB-C, and at least two ports have featured in every MacBook since 2018 (with the first being found in the 2015 12-inch Retina MacBook). USB-C can also be extended through systems such as PCI-E (which is a protocol designed to communicate with devices such as GPUs, network cards, SSDs, etc.) to create “Thunderbolt” ports. USB-C is a very versatile port – functional in 2 orientations (no more trying to insert your USB-A devices in the wrong way), while also having the potential for increased bandwidth, courtesy of the higher number of contacts in the port. In this article we’re going to be investigating this issue and telling you if you need to be worried or not. There have been reports recently that some of these USB-C adaptors have been killing M1 MacBooks. At other moments, you might have to unplug the hub and reconnect before a USB accessory - like an Apogee microphone, in my case - is properly recognized by iOS.You probably use (or plan to use) a dongle or adaptor with your M1 MacBook. Sometimes the iPad will display a “not charging” message for no obvious reason when power is running into a hub. The connection between an iPad Pro and a USB-C hub isn’t perfect and it can be inconsistent. It’s often a game of unplugging and plugging back in.The 2018 iPad Pro is capable of sending 4K at 60Hz to an external display, but I’ve seen next to no hubs that can manage being a middleman if you need that kind of smooth video. You’ll only get 4K at 30Hz over HDMI with the products mentioned here.But if you’re doing sound-critical work on your iPad, this probably isn’t going to do the job. If you just want to listen to music or watch a movie, I think it’s totally passable. The 3.5mm headphone jacks on the HyperDrive and Kanex hubs don’t match the audio quality of Apple’s USB-C headphone adapter.I’m not running iPadOS on my main iPad Pro so I can’t say whether the bug is completely resolved there. Thankfully, it’s also a relatively infrequent problem. It’s very annoying since there’s no telling when it’ll happen. You’re just cruising along in an app, and then boom: black screen and Apple logo. This occurred across all of the products I tested. The iPad Pro tends to randomly restart when receiving pass-through power from a USB-C hub.
