Hi guys, I know there are many threads but I just wanted to make a post about getting my new iMac. I am going to pick it up from my parents place in a couple of hours and I just want to know the things I should keep a look out for when I boot it up for the first time. How do I know if my iMac has any problems such as yellow tint or the brightness hum? I haven't been following all the problems with the iMac but I would like to make sure I got a flawless machine. Any tips? Also this is my first mac purchase in 5 years since i bought my PowerMac. My brothers have gotten iMac's within the 5 years and within a year the HDD has always failed. Any suggestions on prolonging the HDD's life? I am so excited to open my iMac i just hope it doesn't have any of the problems that other forum posters have complained about.
