# Fixing Ethernet

For many Mac models, ethernet support was dropped either in Big Sur or older OSes. For these users we still have kexts for you!

See the below chart for which Macs shipped with which NIC models:

# Marvell Series

Reminder to set the MinKernel to 19.0.0 so it doesn't inject into OSes with the kext already.

# Nvidia Series

For machines with MCP79 chipsets:

Reminder to set the MinKernel to 19.0.0 so it doesn't inject into OSes with the kext already.

# Broadcom Series

For systems with BCM5764M and BCM57765 chipsets:

Reminder to set the MinKernel to 20.0.0 so it doesn't inject into OSes with the kext already.
