The new M6 iMac supports wired network speeds up to 2.5 times faster than its predecessor, thanks to an upgraded Ethernet connection built into its power adapter rather than the computer itself.
Apple has used this arrangement on previous iMac models to keep Ethernet cables off the desktop. With the M6, the port now supports 2.5 Gigabit speeds, up from the M4’s 1 Gigabit connection.
How much does 2.5 Gigabit Ethernet cost?
The upgrade costs $30 on the entry-level M6 iMac and comes standard with the higher-end four-port configuration.
For everyday browsing and streaming, the difference will be minimal, especially if your internet connection is slower than 1Gbps.
The bigger benefit comes from transferring large files across a local network, particularly for users working with video footage, photo libraries, or network-attached storage (NAS).
Under ideal conditions, 2.5 Gigabit Ethernet can deliver theoretical transfer speeds of 312.5 MB/s, compared with 125 MB/s for Gigabit Ethernet. Actual speeds will be lower due to network overhead and hardware limitations.
You’ll also need a router or network switch that supports 2.5Gbps to take full advantage of the faster connection.
Why the Ethernet port is on the power adapter
Unlike most desktop computers, the iMac doesn’t have an Ethernet port on its back panel.
Instead, the network cable connects to the power adapter, which can sit behind or beneath your desk. Both power and network connectivity reach the iMac through its magnetic power cable.
It’s a cleaner arrangement that avoids running an additional Ethernet cable directly to the computer.
The M6 iMac is available for pre-order now, with shipments beginning November 6.
Apple hasn’t confirmed whether the new 2.5 Gigabit Ethernet power adapter works with older iMac models.
