Apple – Support – Discussions – LEAP/PEAP Issues Resolved!! …

Hey guys, I figured out how to fix LEAP/PEAP issues (with at least TTLS/PAP but I assume this fix works for everything).

Here’s what you do.

1) Download the 1.1.1 version of the driver (we have 1.1.0) here:

http://chrisnolan.org/IO80211Family.kext.zip

2) Back up your copy of the driver which is found in /System/Library/Extensions/IO80211Family.kext

3) Drag the new driver into the /System/Library/Extensions/ folder

4) Open up a terminal

5) Type:

sudo chown -R root:wheel /System/Library/Extensions/IO80211Family.kext/

6) Restart

7) Enjoy!
