Wallieballie Posted October 22, 2007 Share Posted October 22, 2007 Hey! Everytime I changes any line within callistohal.kext/contents/info.plist I revicve a error on startup. "Callistohal.kext was installed improperly and cannot be used". Here is the line that I changed. <key>IOPCIMatch</key> <string>0x4e481002&0xffffffff</string> Anyway, when I'm editing the .kext I drag the info.plistfile to the desktop, change the line, and then replace the orginal info.plistfile. Could that be the problem? Link to comment https://www.insanelymac.com/forum/topic/67318-system-extension-cannot-be-used/ Share on other sites More sharing options...
