Can I still use the older Airport Utility 5.5.3 if I install the 6.0 version of Airport Utility? I have a simple network setup, and have read some initial reviews that say the new Airport Utility 6 for Mac OS X lacks some of the advanced settings that the older utility provides. I depend on those settings for my network to operate properly.

Can I still keep the old utility around and use either tool or should I wait to upgrade until I'm sure all the bells and whistles I might need are added to the 6.0 version?



I am going to need to keep the older Airport Software around since some of my devices are too old for the new software, but I'm mostly interested in knowing that I won't be forced to abandon my current advanced settings if I try the new firmware or the new client software.
Mavericks has made some changes which means that AirPort Utility 5.x will not work. Specifically, /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Apple80211 has been updated and will break the older versions of AirPort Utility.



There are two ways to get around this:


Get an older version of Apple80211 and replace the one in Mavericks with it, then run the AirPort Utility binary through Terminal.
Use a modified version of AirPort Utility which includes the file in the app bundle.
