Shaithis Posted May 23, 2007 Share Posted May 23, 2007 Recently updated to 10.4.9 + semtex kernel (via live update script).......Now I am receiving the above error whenever I boot into OSX, plus the system has become super-unstable. Running iTunes (for instance) is ok but if I start another app while iTunes is doing anything results in an instant panic. Likewise, starting a game like WoW and then exiting it, also causes a panic. I tried the replacement IOFamily.kext but it seems to panic the machine as soon as it loads the desktop.... Any ideas would be most appreciated Link to comment https://www.insanelymac.com/forum/topic/51906-system-extensions-cannot-be-used/ Share on other sites More sharing options...
