While the new M4 Mac mini impressed us all with its small size and processing prowess, a USB-C connectivity issue confused many early adopters.
As spotted by AppleInsider, there are posts on several different forums from people who have purchased the Mac mini but are having issues with connected USB-C devices. In many cases, devices stop working or do not work at all. Messages have been posted in the Apple Support Community, MacResource, and Reddit. The issue does not appear to affect any of the other M4 Macs released at the same time.
One pattern that emerges from various posts is that users connect USB-A devices using a USB-C adapter to a rear Thunderbolt/USB-C port. They experience inconsistent connectivity, but once they switch to a front USB-C port, the devices work fine. Some users are reporting issues with devices powered by the rear ports. In some cases, disconnecting the device and then reconnecting it resolves the issue.
The M2 Mac mini had a pair of USB-A ports, but Apple removed them when it redesigned the Mac mini with a smaller design, hence the need for USB-C to USB-A adapters.
The issues apparently don't affect the Mac mini's front ports, which are only USB-C ports and not Thunderbolt. This could be a sign of a communication problem between the adapters with the versatile nature of the rear ports. The adapters might not be enough to maintain the signal the rear ports need to make a connection.
Apple has not yet commented on the subject. If you need to use a USB-A to USB-C adapter to connect a device to a Mac, rely on products made by reputable companies, such as Apple's offering. It's easy to find cheap adapters on Amazon from companies with absurd names, but in our experience it's worth investing in products from well-known companies.
