Installing SSD and new Memory on 2007 Macbook Pro
Hi.
I will be installing a SSD (250gb MX200 SSD) on my old 2007 Macbook Pro (2.2 GHz). I understand that I will not be using all of the power from the new drive because I have SATA 1 not SATA III. I've read, though, that the performance increase is still visible. I am also upgrading the original memory from 2 gb to 4 gb. I bought all the new components off Crucial. I've read instructions and watched videos about the installations.
My main question/concern is this: Will I be able to download OS X Snow Leopard back on my machine without a disc? I am up to Mavericks, which is a huge mistake, and I'm sure part of the reason why my machine has slowed down so much.
I will be using the computer for lots of Photoshop, iPhoto, and other photo editing programs. I have Snow Leopard on another machine and it does fine with all these programs, but I need a more on the go option. Hence why I am switching to the SSD because of its portable benefits.
Lastly, do I need to completely erase my old harddrive if I am putting in a new SSD? Would it be better just to have a clean slate?
Thanks.
MacBook Pro, OS X Mavericks (10.9)
