The newer card has a non osx86 supported rt61 chip (only ppc driver available) and comes with wpa2 support. WPA not working with manual config, but try this guide to get it going (not tested).used Leo4all v3 Used RT2500 "STA_Cardbus PCI" Driver & Utility from Ralink Website - the Tiger version (dated ).First install Realtek Drivers from  (USB RT2870) Restart with -f and -v look for a ralink driver being loaded.Then go to Network in System Preferences, hopefully it will appear. If it isn't there try sudo kextload RT73in terminal.Does not show up in System Profiler at all, but works if you disable ("Make Service Inactive") the wired ethernet port (en0).Also this was on an unmolested Kalyway 10.5.2 DVD Install.It will boot off cd, and install, partition..will not work.
Install the package, then install Jas Combo Update 10.5.3 No need for aditional patching, kexts editing etc.I could not install Kalyway 10.5.2 DVD at first and got an error "Could not validate Base Install". New DSDT Method :- run the DSDT Patcher with -new HPET from terminal, edit the dsdt_in Debug Folder (search and replace 'AZAL' with 'HDEF') recompile the (iasl dsdt_fixed.txt), copy the to / - copy the chameleonsm (cp chameleonsm /boot). Avoid NVinject kext since it may not be compatible with all NVidia graphic boards (NVinject may cause bootup crash), use the proven LS8 pack instead. showtopic=96725&st=0&p=690751entry690751 For another hackintosh user experience After upping my memory voltage by .20 it worked fine. Before reboot remove/backup all patched kext files, run "kextcache -a i386 -m /Extra/Extensions.mkext /System/Library/Extensions/". showtopic=121031&st=0&p=856502entry856502 This is a perfect system! And really cheap (54€) Note: Some distributions might not support video resolution over 1280x1024 out of the box.Template:10.5.2 This is a component level hardware compatibility list.
We want to keep it as accurate as possible, but please, do not entirely rely on this list when buying hardware.
Note: sometimes drops connections, could be due to other OSX issues. This adapter is available retail at Microcenter and online at Amazon, Newegg, etc. Works fine with manufacturer supplied drivers, good network pickup on directional receiver. After installation of supplied drivers it works fully.
