I just wanted to test it, because i thought everything will be working fine if i put the old Extensions back and repair permissions.
Because of some issues on the first hackintosh, which the other hasn´t, i copied all the kext from the first one to another place on my Volume and put the kexts from the second one to the S/L/E of the first one, repaired permissions and emptied the cache then i tried to start and what a surprise Kernel Panic. On my pc are two hackintoshs installed, the first one which is now ****ed up and the second one which is still running. I had a succesfully installed hackintosh on my pc, but then i made a terrible experiment and now i know the mention of 'never touch a running System'. Building a CustoMac Hackintosh: Buyer's Guide
