    Dear experts, i just got my new 27" iMac (i5, 680MX, 1TB Fusion) now i would like to test that i have no problems with my hardware, display, etc. how would i do this? which tools?

    thank you for your guidance here, i am sure many other would be also interested to check their new iMac's,,,it's quite big investment.

    Honestly Im not one to try to stress test a new iMac to find faults..
    All I will be doing is checking for obvious cosmetic damage, That the specs are as I ordered, and then Im going to use it.. with a smile

    I reckon If I look hard enough I'll find something not quite perfect. and i'd rather not!

    If a 'fault' isnt apparent in my every day use, then to me.. its not a fault.

    I dont want to spoil my new toy feeling by looking for miniscule imperfections that would then bug me.

    I have to say, I had a long list of things to do and I did have a good close inspection, put it through its paces but I didn't do any of the formulaic tests.

    I had a shopping list ready, but didn't go through with it. Probably too lazy. Or didn't want to find any faults as I really don't want to wait for weeks to get a replacement. Besides, with AppleCare I am sure problems will be sorted whenever they arise.

    Here's my shopping list in case it helps:

    Image retention test:
    1. Set your background to dark gray (Preferences>Desktop&Screen Saver>Solid colors> and look for the dark gray at middle top row of solid colors
    2. Pull up safari and go to your fav website and leave it up on your screen for 10 minutes (example, you can leave anything static on your screen)
    3. Minimize Safari and see if you have IR

    Other checks:

    Dead pixels?
    Backlight bleed?
    Stuck pixels?
    Scratches on aluminum?
    Scratches on glass?
    Yellowing on screen?
    Uniform color across screen?
    Level display or crooked?
    Image Retention?
    Fan noise?
    CPU matches order?
    GPU matches order?
    RAM matches order?
    Camera works?
    Speakers work?
    Fusion drive matches order?
    Brand of hard disk (Would appear the Seagate Baracuda ST1000DM003 is better than the Western Digital WD10EALX)?

    You should of course check a lot of things to ensure that you got what you paid for. You don't buy a car without test driving it, right?

    I did check that all the hardware was correct and that it worked as it should, I checked for image retention, dead and stuck pixels and yellow tint.

    The only "issue" I've had so far is a little bit of backlight bleeding in the bottom corners but I can barely notice it even I turn the brightness up to the max and look at the screen from an extreme downward angle. But then again, it's pretty much impossible to get a screen nowadays without any backlight bleeding whatsoever. If you have then consider yourself super lucky.

    I'm extremely satisfied with my 27" iMac so far.

    The point I'm making is this

    If I go and look for problems - you bet I'll find them.

    If there IS a problem. Ill see it in normal use. Ie. no need for IR testing etc.

    It will become obvious quickly if any issues are there. And if they are apple will sort it.

    I'm coming from a genuine positive headspace of assuming its ok unless I see otherwise

    As oppose some people who have tied themselves in knots assuming their machine will be faulty and then going out to look for the faults.

    I doubt anyone has absolute perfection. So if you look hard enough you will find something that will just disappoint you. You may not even have noticed until you went looking

    Once you know about a tiny tiny flaw in a display. You will constantly be drawn to it.

    Everyone's tolerance of imperfections is different. I'm a fussy woman. But I have faith in the product I bought and the AppleCare. I wouldn't have bought it otherwise

    So I'll save myself the stress and just enjoy it

    Check optical drive

    I just bought a used Imac 24 inch and it will not read audio CD.

    Just take it back. Odds are you will find a flaw so why delay the inevitable?

    Key, test for me was to see if there are any dead pixels as I find them very annoying. Download Pixel Check and run it.

    Otherwise quick look for dents/dings and off you go - enjoy it!

    Hmm... when I get mine that I ordered 3 weeks ago I will only be checking the following and hoping nothing stands out (or else for me it means another 6-8 week wait):
    1. Hardware specs match what I ordered.
    2. No dents or scratches on body (I'll accept small scratches on the backside)
    3. Nothing is visibly wrong with display (dead pixels).
    4. Machine shuts down/starts up/restarts ok.

    If the above checks out I'm a happy camper.

    Great list!
    I didn't have a list, but I literally did every single one on there in the course of checking my machine.

    Great Check List

    Anyone who says you shouldn't stress test or check your iMac out is misleading you. The iMac can be stressed, its not a paper towel. It's a hardcore piece of equipment and can handle 10 minutes of a checkerboard, and or checking to make sure your fans are ok, etc. You have 14 days to check your iMac out, and thats why Apple lets you get a replacement within 14 days. So if you don't want to check it, then I have a few cars I would like to see you as well ;)
