Greetings mac Rumors! I am the proud owner of a 2007 white Core 2 Duo macbook! I love the machine. Since december 2007 it has not failed or given up on me. Running with 4Gb of Ram and a 240Gb solid state shes a nice machine! I installed ML on it and everything worked perfect minus the wireless. i couldnt figure out how to install the kext.... BUt other then that perfect. heck the video was more smooth then lion ever was. My dilemma is the fact that if i cannot get mountain lion running smoothly on this system (so basically get the wifi driver running) im going to be running snow leopard or maybe Lion. This laptop has made it 7 years and although with new RAm, battery (this fall and SSD) its getting a bit old.. I was wondering other then the standard 13' macbook pro released in 2012 are there any other macbooks that are still user upgradeable?
