I have a first-generation MacBook (paleolithic era, mid-2006) that has served me well for six years. Last weekend, I migrated all of my data to a new iMac. I then reinstalled OSX Leopard and Snow Leopard on the ancient MacBook, effectively wiping it clean. My MacBook is a Core Duo, not a Core Two Duo, so it can't run Lion. The MacBook is working very well again, but I'm wondering if there's anything else I can do to maintain its health and wellbeing for another six years. I am thinking about getting a solid state drive to prolong its usefullness. Anyone else in the forum put a SSD in a cheap, old MacBook? Thanks for any serious and humorous suggestions!
