guy's after updating to 10.8.4 i'm hitting a major problem, external usb/hard drive's wont detect anymore and all i'm seeing in my console is the following error :
kextd[8088]: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFData _fastCStringContents:]: unrecognized selector sent to instance 0x7fab2dd2bdf0'
com.apple.kextd[10392]: Kext id com.apple.kernel.iokit not found; removing personalities from kernel.
ReportCrash[10391]: failed looking up LS service ( scCreateSystemService returned MACH_PORT_NULL, called from SetupCoreApplicationServicesCommunicationPort, so using client-side NULL calls.
ReportCrash[10391]: LaunchServices/5123589: Unable to lookup coreservices session port for session 0x186a0 uid=0 euid=0
for some reason i'm thinking my kexts are fubared anyone has an idea what i can do ? the system seems to work but some apps are really slow and not beeing able to read external drive's is really bad..
