How to Install Rtl8723ae Kext for Mountain Lion

Rtl8723ae is a wireless network adapter driver for Realtek devices. It allows you to connect to Wi-Fi networks using your Mac computer running Mountain Lion (OS X 10.8). However, this driver is not included in the default installation of Mountain Lion, so you need to download and install it manually. Here are the steps to do so:

  • Download the Rtl8723ae kext file from this GitHub repository.[^1^] You can either clone the repository using Git or download it as a ZIP file.

  • Extract the ZIP file if you downloaded it and locate the Rtl8723ae.kext file inside the Release folder.

  • Copy the Rtl8723ae.kext file to /System/Library/Extensions/ on your Mac. You may need to enter your administrator password to do this.

  • Open Terminal and run the following commands to rebuild the kext cache and fix permissions:

sudo kextcache -system-prelinked-kernel

sudo kextcache -system-caches

sudo chmod -R 755 /System/Library/Extensions/Rtl8723ae.kext

sudo chown -R root:wheel /System/Library/Extensions/Rtl8723ae.kext

  • Reboot your Mac and enjoy your Wi-Fi connection.

Note: This kext is compatible with Mountain Lion (64-bit architecture) but should work with Lion too. It may not work with Snow Leopard or older versions of OS X.[^1^]

What is Rtl8723ae and why do you need it?

Rtl8723ae is a driver for Realtek RTL8723AE Wireless LAN 802.11n PCI-E NIC devices.
