Hello I'm upgrading the hard drive in my Macbook to a 1TB one, partitioning and installing Mac/Windows/Linux. It's one of those 2.5" that are 0.5mm larger than the usual ones, I hope it still works. When I install Mac, do I have to install Leopard, THEN upgrade to SL, or can I just install SL (it's an upgrade disc) without the Leopard disc that originally came with my Macbook? [verybadlyexplainedpart] Also, my family and I have used 4 out of our 5 iTunes account... things. Is there any way to 'sign out' of iTunes on my current HDD, on my Mac and Windows partitions to free up 2 of the 4 login things? [/verybadlyexplainedpart] Thanks!
