AirPort Utility v5.6.1 Launcher

What the Launcher Is, What the Launcher Does, and Why It Exists

The Launcher is a small utility for OS X (compatible versions listed, supra). Using the Launcher, it is possible to run AirPort Utility v5.6.1 under versions of OS X that would otherwise reject the application. This older version of AirPort Utility is needed to configure older AirPort units (both AirPort Express and AirPort Extreme). For whatever reason, Apple updated AirPort Utility and the new version does not support older AirPort units; obviously, this presents a problem for people who still own these older units.

Everything the Launcher does can be accomplished through Terminal (access to a machine running OS X 10.6 Snow Leopard is also required). The details of how to do this are included, infra.


How the Launcher Does What It Does

With the release of OS X 10.9 “Mavericks” Apple updated file Apple80211 (contained in /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A). Whatever the other effects of this update, it broke backwards compatibility with older versions of AirPort Utility. Thankfully, the fix is simple: Inject an older version of the file when launching older versions of AirPort Utility. This is precisely what the Launcher does.

When you run the Launcher, it simply injects the OS X 10.8 “Mountain Lion” version of file Apple80211 (which the Launcher contains) and then runs AirPort Utility 5.6.1 (which is included in the download of the Launcher). That’s it. One file is the difference between AirPort Utility 5.6.1 running and throwing an error under more recent versions of OS X.


Unless you specifically know that you want a *.zip file instead of a *.dmg file, download the *.dmg version.

If, for some reason, you do not want the *.dmg version, download this one (both the *.dmg and the *.zip contain exactly the same files, they are just packaged slightly differently).

If you would prefer to use Terminal to launch AirPort Utility v5.6.1 instead of the Launcher, you will need this file. (You can also grab this file from one of your own machines if you have one running OS X 10.8 “Mountain Lion”.)

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.

Usage Notes

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 as an “identified developer”. Consequently, you will almost certainly receive the following prompt when running the application (at least the first time):
AirPort 5.6.1 Launcher Warning

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:

Security & Privacy Pane: AirPort 5.6.1 Launcher

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 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.

Every so often, the caching on my site decides to make these download links not work. I am working with my hosting provider and the plugin author to get this issue resolved; however, in the meantime, I have made available an alternative download source here. If you have trouble using both of these methods, please contact me directly.

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.appAirPort Utility 5.6.1 and AirPort Utility 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.
