My darling macbook works hard, and I'm continually cleaning up to keep functional. I have decided to spend about £100 on birthday upgrades, but my problem is, while I've done a lot of reading and youtube watching, I'm still not sure of the order of play. Given this mac: A Snow Leopard upgrade disc A Western Digital Scorpio 250GB 2.5" SATA 5400RPM hard drive And Kingston DDR2 PC6400 SODIMM - 2 x 1GB Kit My questions are Is this the right kit? What is the order of play? I have the original Tiger reinstall discs. I hope this makes sense. I'm new to the world of upgrading computers, but I have the phillips 00 and the torx bits, half a brain and not a lot of cash.
