View Full Version : Help required! Kernel Panic after IOUSBFamily Install - Send Me Your IOUSBFamily.kext

Apr 10, 2009, 10:39 AM
Hi everyone,

I was downgrading to the 10.5.5 version of IOUSBFamily (I'm running 10.5.6) from here: http://developer.apple.com/hardwaredrivers/download/usbdebug.html .
Unfortunately, after doing this my system panics when it boots. Even single user mode doesn't work as the IOUSBFamily is incorrect.
Luckily, I have a Windows partition that I have booted in to, and I have downloaded MacDrive so I can access my Mac Partition.
Could someone with 10.5.6 please upload their IOUSBFamily.kext found in System/Library/Extensions/ ? If I can copy this back on to the Mac drive in the correct location then I think it should start booting again.

Do you have a PowerPC or Intel Mac? I happen to have both kinds handy, with 10.5.6 running on each one, but I won't be able to package up the kext file until I return home, where my Macs are.

I have an Intel iMac, sorry for not putting that in the post.
