Hey everyone Before pulling the trigger to buy a new imac I had been lurking these forums to prepare for every common issue i'd encounter. (Yellow tint screen, high pitch noise, etc). I went ahead, hoping for the best and ordered it. The computer arrived 2 days ago. This post is for those who are waiting, and just a general report since my computer serial revealed that it was built in June 2010. Serial Lookup: Serial number: Q002307xxxx Name: iMac Intel (mid 2009-i7) Group1: iMac Group2: Intel Generation: 8 ModelCode: imac_mid_09 CPU speed: 2.8GHz Family name: A1312 Screen size: 27 inch Screen resolution: 2560x1440 pixels Memory - number of slots: 4 Factory: Q0 Please tell us where this machine is manufactured. External link: Technical specifications by apple-history.com External link: Repair guide by iFixit Model introduced: 2009 Production year: 2010 Production week: 23 (June) Production number: 268 (within this week) Uitbreidingen: Uitbreidingsmogelijkheden van dit apparaat My profession is doing music and design work. Its my main income and ive been doing this for almost 10 years. These issues play an important role for me BUT I cannot yet say if the issues I have hinder my work yet since ive only owned it for 2 nights. Take this report for what it is. Screen: There is a slight difference between the bottom 1/3rd of the screen and top 1/3rd. The bottom is warmer and the top is cooler. The middle or the top seems to be the most neutral in my opinion. When i did the grey-band test (there is a post in this forum with a link to the test and lots of posts about it) I could tell the bottom gray is yellower/warmer. It's very slight and not annoying at all compared to user photos of their horrible yellow tints. I've dealt with worse color shifting/color representation using the couple 23" apple cinema displays i used to use (purple fringes, pink parts of the screen etc). The work I've produced on those monitors did not have any issues. High Frequency Noise: Some people have been complaining about iMacs emitting a high frequency pitch/noise that comes from the computer (not the speakers) when user is adjusting the monitor brightness. In my research people have mentioned that their flat panel LCD TV's also suffer from this as well. The high pitch noise that people are suffering with is very apparent on my computer. When the screen is at its 100% brightness (highest notch) there is no high pitched sound. If I reduce to second brightest notch and 3 notches below from that the noise is very apparent. Piercing to a point you will get a headache. I cant imagine working with that sound in my head. The lower screen brightness below the -3, notches brings no noise. Its weird and aggravating issue. However during night time, i keep the brightness pretty low. Day time i keep the brightness at max or middle. It seems like the issue can be worked around in my day to day use... but its very odd thing to work around. I dont believe that customers should work around this issue but... whatever. Build: The base of my imac shipped slightly bent! Uploaded with ImageShack.us This probably will reduce my resell value (down the line). If i didn't have this issue I would be very on the fence if i should return it for a replacement. Overall: Screen is beautiful. No dead pixels. The machine is fast. Cubase, Live, Reason, CS4, all run extremely well. I was running first generation mac pro 2.66 with 12 gigs of ram before. Its snappier than that machine by far even though my imac only has 4 gigs of ram. I havent done any large projects on it yet since ive only owned it for 2 days. I ordered my machine from macconnection. Customer rep will contact me tomorrow (monday) to talk about a replacement. Hope this helps in any for for those who are waiting.
