Hi all, Just to share: for those who are trying to install the driver for TP-Link's TL-WDN3200 (chipset should be RT5572?) USB wireless adapter for Mac OS, you can find it here: http://www.mediatek.com/_en/07_downloads/01_windows.php?sn=502 Choose to download the one that says: USB(RT2870/RT2770/RT3X7X/RT537X). Open that up, install it; Then open your "System Preferences"->"Network"; It should then automatically detect the new network connection. Done. Got this to work on my Macbook Pro running on 10.6.8. Cheers!
