Command Line Wireless Options in OS X

Managing OS X wireless options was a terrible mystery until I discovered the magical hidden ‘airport’ command. If you do any Mac sysadmin work, I recommend:

sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport /usr/sbin/airport

This gives you lovely, straightforward access to the airport command, from which you can turn wifi on and off, configure administrative settings; basically everything you need. However, watch out; there’s been a change in the version currently shipping in Mavericks. My fave command was:

sudo airport en1 prefs RequireAdmin=YES

But this will no longer work. Instead you receive this response:

'Unrecognized prefs option 'RequireAdmin=YES'.

It’s not a problem, because Apple have actually unpacked the RequireAdmin option into it’s three constituent parts; RequireAdminIBSS, RequireAdminNetworkChange and RequireAdminPowerToggle. You can now control each of them individually.

So my favourite command has now become:

sudo airport en1 prefs RequireAdminIBSS=YES RequireAdminNetworkChange=YES RequireAdminPowerToggle=YES

Reflash System for OpenFrame

Latest Release: 19th September 2014

Download System v1.11 – (160MB) MD5


Originally written for the O2 Joggler, the latest version of the Reflash System can be used on both types of the commonly available OpenFrame units. These are great devices; useful, hackable, affordable and fun. However, if you find yourself with one that’s less than happy, with any luck this system should bring it back to life.

This is designed to be a reliable method of reflashing any OpenFrame device, even in the event that the internal flash memory has had it’s partitions destroyed. These units are robust and will continue to boot from external USB devices even when the internal memory has given up, so unless you have a hardware failure or EFI problem this should get things working again.

In addition, this system can also be used to write a completely different OS to the internal memory, such as SqueezePlay OS. Instructions are provided below, but the alternative OS should have been designed to run from the internal memory. You could potentially flash anything, but not everything will work.
