I just purchased a new Macbook (older version). It came with 1GB RAM and a 120GB HD. Before I get started I am going to upgrade the RAM to 4GB and the HD to 320GB (should arrive today). I thought I'd follow the suggestion of another user and manually load the OS so that I can cherry pick languages and drivers, so to save space. Anything else, wrt a manual load, that would be a good idea? I want to be able to view MS files (eg: Word, .wmv, etc) and Adobe files. Will my Mac decode .wmv out of the box or is there a mod required? Is buying Office for Mac the best solution viewing Office docs? I rarely create docs but receive many via email and have hundreds on my HD that I'd like to view. What about Adobe (.pdf) files? I used Firefox on my latest MS laptop...do most Apple users find that the best? Lastly, what are the basic first steps, after swapping out the HD and powering the unit ON, to load the Mac OS? Just need someone to point me in the right direction. Thanks for any suggestions to any, or all, of the above.
