A New, Simple Solution
A few days ago, I posted a workaround to get AirPort Utility v5.6.1 working under OS X 10.9 Mavericks (old post, infra, under “Old Post”). That workaround involved renaming or replacing a system file and then launching AirPort Utility via Terminal. Now, that solution still works (and is included in the collapsed “Old Post” section, infra) but it was far from ideal. Most users would prefer not to have to alter or replace system files (even if the replacement is simply an older version of the same file from Apple), so I continued looking at the problem. Today, I am posting a better solution.
AirPort Utility v5.6.1 on OS X 10.9 Mavericks
As I stated in the previous version of this post, the issue with AirPort Utility v5.6.1 under OS X 10.9 Mavericks is that a system file upon which AirPort Utility relies was updated in 10.9 and that update broke backwards compatibility with AirPort Utility v5.6.1. The file in question is Apple80211 in /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A. Replacing this file with the older version allows AirPort Utility v5.6.1 to be run under 10.9, but only via Terminal (i.e., double-clicking it will not launch it, it will throw an error).
However, there is a way to get around this issue by importing the older library into AirPort Utility v5.6.1 before running it. That is what the new solution, downloadable, infra, does.
Note: you can bypass having to go into System Preferences, detailed infra, by simply right-clicking (or control-clicking) on the Launcher and then clicking “Open” from the pop-up menu instead of double-clicking to open it.
I have not signed this application (i.e., AirPort Utility v5.6.1 Launcher.app) as an “identified developer”. Consequently, you will almost certainly receive the following prompt when running the application (at least the first time):
As long as the warning looks like the one I’ve given here as an example, everything is fine. Of course, once you click Open, Gatekeeper (OS X’s relatively new security feature) will identify the application as being from an “unidentified developer” and, unless you’ve changed the default settings, it will prevent the application from running.
In order to allow the application to run (and thereby to launch AirPort Utility v5.6.1), you will need to navigate to the Security & Privacy pane in System Preferences. Once there, you will see this notification under the General tab:
Click the “Open Anyway” button. AirPort Utility 5.6.1 Launcher should run and launch AirPort Utility v5.6.1 without anymore work on your part. Additionally, future uses of the launcher should not require any of the foregoing steps (except running the launcher itself). n.b., any time you want to use AirPort Utility 5.6.1, you must launch it via the launcher application (i.e., AirPort 5.6.1 Launcher.app) instead of by double-clicking on AirPort Utility 5.6.1; this is due to the fact that the launcher must inject the older version of the Apple80211 library or else AirPort Utility 5.6.1 cannot run under OS X 10.9 Mavericks.
Download AirPort Utility 5.6.1 for OS X 10.9 Mavericks
Please select either the *.zip version or the *.dmg version (they contain the exact same files):
AirPort Utility 5.6.1 Launcher (17259 downloads)
AirPort Utility 5.6.1 Launcher (*.dmg) (15905 downloads)
The .dmg download may not work in Chrome; to resolve this issue, simply use Safari or Firefox (or download the .zip version, which contains the exact same files).
This is due to some conflict between Chrome and Download Monitor, which will hopefully be resolved soon.
Once downloaded, the zip should automatically expand (if it doesn’t, just double-click it to expand it manually) and create a folder entitled “AirPort Utility 5.6.1″, keep this folder.
AirPort 5.6.1 Launcher.app and AirPort Utility 5.6.1.app are both included inside this folder. Whenever you want to use AirPort Utility v5.6.1, just run the launcher either by double-clicking it or via Spotlight. And that’s it, you now have a working version of AirPort Utility v5.6.1 under OS X 10.9 Mavericks.
