Fork of Mieze's Intel Mausi Network Driver by RehabMan

How to Install:

Install to /S/L/E or /L/E using your favorite kext installer.

Or if using during installation, copy the kext to EFI/Clover/kexts/Other.

There are no real changes in this repo. I only forked it so I could have a build on bitbucket for automated scripts which download and install (via and used by my guides)

I will occasionally update the repo to sync with Mieze's changes (after testing).


Downloads are available on Bitbucket:

OS X driver for Intel onboard LAN

A few days before Christmas I started my latest project, a new driver for recent Intel onboard LAN controllers. My intention was not to replace hnak's AppleIntelE1000e.kext completely but to deliver best performance and stability on recent hardware. That's why I dropped support for a number of older NICs. Currently the driver supports:

  • 5 Series
  • 82578LM
  • 82578LC
  • 82578DM
  • 82578DC
  • 6 and 7 Series
  • 82579LM
  • 82579V
  • 8 and 9 Series
  • I217LM
  • I217V
  • I218LM
  • I218V
  • I218LM2
  • I218V2
  • I218LM3
  • 100 Series
  • I219V
  • I219LM
  • I219V2
  • I219LM2
  • I219LM3

Key Features of the Driver - Support for multisegment packets relieving the network stack of unnecessary copy operations when assembling packets for transmission. - No-copy receive and transmit. Only small packets are copied on reception because creating a copy is more efficient than allocating a new buffer. - TCP, UDP and IPv4 checksum offload (receive and transmit). - Support for TCP/IPv6 and UDP/IPv6 checksum offload. - Makes use of the chip's TCP Segmentation Offload (TSO) feature with IPv4 and IPv6 in order to reduce CPU load while sending large amounts of data. - Fully optimized for Yosemite and Mavericks (64bit architecture) but should work with Mountain Lion and Lion too, provided you build from source with the 10.8 or 10.7 SDK. - Support for Energy Efficient Ethernet (EEE). - VLAN support is implemented but untested as I have no need for it. - The driver is published under GPLv2.
