Apple service providers are reportedly seeing Apple Silicon Mac mini logic boards with 10 Gigabit Ethernet in an internal parts list.
However, in a repair parts list meant for Apple Authorized Service Providers, obtained by MacRumors, every Mac mini logic board without 10 Gigabit Ethernet has a corresponding logic board listing that includes the networking technology.
Sources inside Apple's service chain not authorized to speak on behalf of the company told AppleInsider that those part numbers are placeholders and don't correspond to an existing part. It isn't clear to the sources if Apple ever intended on making those parts, or if they are reserved for a future refresh.
For prospective Mac mini buyers that want or need 10 Gigabit Ethernet, Apple still has Intel-based models available for purchase with the upgrade option, and some Thunderbolt 3 docks incorporate the technology as well. Those Intel Mac minis also have four Thunderbolt ports, instead of the two ports on the M1-based devices.
