Hiya, my late 2008 2.4 Ghz core 2 duo Macbook aluminum is a bit clogged up so I got a new Seagate 750 GB hybrid SATA harddrive to replace the 250GB one in situ. Problem is, after being all excited to get started, I am losing my nerve! I am currently running OS X 10.5.8 and just purchased 10.6 from Apple. The disks have arrived but I haven't installed it yet. I also intend to increase the RAM, from the current 2 GB to perhaps 6 or more. (Bit concerned 8GB may cause problems). In any case, what would you recommend would be the ideal order to perform these three tasks, i.e. A) new harddrive install, B) new OS install and C) RAM upgrade? ABC? CBA? Any advice welcome. It's been ages since I cracked the case of my (20MB!) Mac SE to add more RAM, I think I may have lost my touch!
