Support for Energy Efficient Ethernet (EEE) which can be disabled by setting enableEEE to NO in the drivers ist without rebuild. Note that older versions of macOS might not support 2.5GB Ethernet. Supports jumbo frames up to 9000 bytes (strongly recommended for 2.5GBit operation).įully optimized for Mojave and above. Support for TCP/IPv4, UDP/IPv4, TCP/IPv6 and UDP/IPv6 checksum offload. TCP segmentation offload over IPv4 and IPv6. TCP, UDP and IPv4 checksum offload (receive and transmit). Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission.

Note: I have noticed that in Mavericks the Mountain Lion driver is a bit touchy.
Your adapter should be active and the Ralink menu should now be in the tool bar and selection "Open Wireless Utility" should now work.When done shutdown, plug in your USB Wireless adapter, and start back up.It will take a few minutes for the script to finish running.Download the file below, "postinstall", to /RT2870Resources.
