Hey,
I have a perfectly working version of OS X 10.5.5 (except for shutdown i have to press the button) that I installed using iDeneb. I did the extension changes so everything work.s the only problem I have is with Logic Pro 8. I get the error "error while trying to synchronize audio and midi" with a message following about the sample rate. I am using an audio kontrol 1 but the problem also happens with the built in card. Please help with this problem. The message shows up after around 4 bars usually. I believe it might be a problem with the kernel but I am not sure how to change the kernel and which one i might change it to. Adobe/garage band work fine so i don't think its a problem with the interface. I have a d630 2.5gHz 4GB ram

4GB 667 DDR Ram
2.5 GHZ processor

If your using intel make sure ur using Vanilla, if your using AMD you can try a new kernel Called Voodoo, about the error can be a not fully supported Audio Card, for shutdown try installing this

How do I go about installing the vanilla kernel. I have the voodoo installed now I believe. I downloaded the mach_kernel vanilla file but i don't know how to install it

Please type this in terminal to know your kernel

uname -a

Darwin ben-******s-latitude-d630.local 9.5.0 Darwin Kernel Version 9.5.0: Tue Oct 14 07:39:11 IST 2008; Voodoo; Beta 2c :xnu-1228.7.58/BUILD/obj/RELEASE_I386 i386

So yeah it looks like I'm using the voodoo kernel. How dod I switch to vanilla without having to format?

Nah your using Voodoo, but looks like your using voodoo beta 2, try to get the final one, check it out here
