Confirmed to be working on a clean OS X 10.9 Mavericks install. This seriously saved my bacon as the official drivers don't even install the needed kext (I looked for it everywhere with no luck) and the last installer I had seems to be stable Mountain Lion and earlier. Even though this is a "bear extender" app it works for
all Railink RT2870 chipset products.
I have the infamous
Linksys WUSB600n v2 which needs additional configuration in its Info.plist file in the kext itself.
To install for the Linksys WUSB600n v2 follow the instructions on the PDF, to remove any traces of previous driver installations.
- Open the uninstaller package file, let it do it's thing and then restart your CustoMac
- When rebooting be on the safe side and use the -f (ignore kernel cache command) on the Chimera boot loader to flush out any traces of the old kext.
- Once booted open the installer app but don't restart once propted
- Navigate to ~/System/Library/Extensions and go to RT870USBWirelessDriver.kext
- Right-click and select show package contents
- Open the contents folder and Copy the Info.plist file to the desktop
- backup the current .kext file for safe measure
- Open the file in your text editor of choice
- Command+F and find linksys go past the second entry and copy/paste the code right underneath it
Code:
<key>Linksys - RT2870 - 3</key>

<key>CFBundleIdentifier</key>
<string>com.Ralink.driver.RT2870USBWirelessDriver</string>

The green indicator in the Network preferences show a fully working system! I hope this helps anyone.
