Just a quick question. One week ago my HDD in my 2009 Mac Mini died an I put an SSD in there which I already had. Installed a fresh copy of 10.9.5 on it an began to install the services I need. Now I got a new late 2012 MacMini - moved the internal HDD to the empty slot and installed the SSD, too. Well my question is, do I need to start from scratch again or has OsX all drivers /kexts on board for the new hardware. It boots up normally and it looks like all hardware is recognized. Any thoughts on this?
