I just switched to Mac from using PC's for the past zillion years. I bought a mid 2010 iMac - 21.5" refurbished from the Apple Store - I love the system and I'm slowly getting used to finding my way around. The refurbished unit came with 4 gigs of Ram - I've since added 4 more for a total of 8. It also stated it came with a 1 TB hard drive - it actually came with a 2 TB hard drive, so I lucked out on that part. My question is - how do you find out the brand of hard drive - I've searched everywhere to find the actual brand names -- I'm assuming it's not a Seagate, but wanted to verify that - no doubt there's an easy way to check - I just haven't found it . Thanks in advance !
