Hi board, Thanks in advance.... I just upgraded my 2008 8.1 24 inch Imac w/ a 1 TB ssd. I am using carbon copy cloner to clone. I hit a wall of sorts; I believe it has to do with Yosemite. When I attempt to clone, I get an error message reading: "destination volume will not be bootable because required system file mach_kernel does not exist at the root of the source volume'". Can anyone assist?
