Cleaning the quad core 27" iMAC screen

Does apple have any "official" suggestions on how to clean the 27" LCD screen?
regards

My personal view--if you want to be absolutely safe, just moisten a soft cloth the next time you make hot soapy water for washing dishes by hand (before washing any of the dishes, of course). Use the cloth to spot clean any marks on your display. The important things to keep in mind are to never spray any liquids directly onto or around your computer and to always make sure the damp cloth is only slightly moistened. Wring out the cloth thoroughly before using it on your screen.

I have a mid-2010 27" Quad Core i5 iMac running 10.8.3. Startup disk recognizes the primary hard drive as a startup volume but will not boot from it. Have tried zapping PRAM, ran disk utility. No errors reported Any thoughts?

My bad Eric. The startup preference recognizes the primary as a 10.8.3 startup volume but when u select it the system does not boot. I can only boot from my external backup drive

Is there anyway to add a 3rd display to the quad core iMac 27?

Is there anyway to add a 3rd display to the quad core iMac 27? I know a 2nd can be added using the mini port.. but curious to see if there is a solution to add a 3rd if desired.
Thanks!

As Sherman says, the only way to add a 3rd display to an iMac or MacBook is to use a USB to DVI adapter. I've been using the Gefen adapter for a year or so now with my MacBook Pro and it works great:

But USB does not have a lot of bandwidth, so you can't use it for video, games and other similar stuff. Works great for Mail, web browsing, iWork, etc.

Picking Up the Quad Core 27 inch iMac in my local Apple Store

Hey All!
I'm picking up a new iMac this friday at my local Apple Retail Store. I am going for the Quad Core model, now can I pick this up in the store or can I only order it on The Apple Online Store. If in retail store... Can I get i5 or i7 in store or just i5
- Thanks!

That is correct . . . I bought my i5 at the local Apple Store but had to order my i7 from the on line Apple Store, however, yesterday I noticed that MacMall had i7s available for next day shipment.

I am getting a message in the middle of my imac screen instructing me to hold down the on-off button and turn off the machine. The message is in several foreign languages beside english, and there is not way to get rid of it. The curser is inactive.

I am getting a message in the middle of my imac screen instructing me to hold down the on-off button and turn off the computer. The message is in several languages and completely takes over the computer disabling the mouse and all other functions. The only option is to unplug the computer or turn it off. I'm concerned that this is a virus. It does not look like it's related to Apple or the imac OS.

That sounds like a kernel panic. These are generally hardware related, often caused by poorly seated or fauly RAM.

PCIE, PCI, and the quad-core

I have recenty bought the new Quad-Core, a machine that I am very happy with. However, there is one aspect about it that I am not completely clear about. I understand that the PCIe and PCI cards are not interchangeable. Does the quad-core not have a standard PCI slot? In other words, for any video capture cards or other upgrades, I can only use PCIe, correct?

Well, I'm glad it is cutting edge, but the costs definitely hurt. I'm looking at $589 for a video capture card and monitoring system. PCI is as little as $300. Oh well!
Thanks for your input, I appreciate it!

BTW, what happened to all the quad core phones that were supposed to come out last summer?

Reps at Best Buy and sever articles cited they should have been released last summer????

they were released in europe
in the use the quad core was replaced with a dual core because we dont want to pay for the quad

2.66 Quad Core or iMac?

OK, I know this is probably a stupid question, but I want to ask it anyways...
If given the choice between the MP Quad Core 2.66 or 24" iMac 2.93 GHz for graphics work (Photoshop, InDesign, Illustrator), which would you choose?
A no-brainer I assume, but I am actually confronted with this situation, caveat being, if I go for the MP I would need to use my current monitor (an older Sony CRT 20 incher) where with the iMac I would have the 24" LCD screen at the start. Both systems would be maxed with RAM (8gb) and the iMac would have the ATI Radeon GPU upgrade.
Thanks in advance.

Mac Pro for sure. The first gen still has A LOT of life still left in it. Sure the iMac is new, but it just lacks upgrade ability. A key option being the adding of multiple hard drives, and fast drives, ram, etc. Working in Photoshop with large files, you probably want a dedicated scratch disk or raid 0 volume for scratch.
I just recently installed a 5th hd in my own mac pro 1st gen. utilizing the 2 extra sata ports. I fits perfectly in the lower dvd drive space.
There's a good tut here:
http://www.tenthousandpercent.com/?section=other&article=65
BTW, in the tutorial, you don't have to break the sata cable, or use an "L" angle one either. A regular "I" sata fits perfectly.
Also, in terms of GPU, (a good link from hatter) apparently the new Ati 4870 graphics card upgrade is also compatible with 1st gen mac pros.

Compressor 3.0.5 wont use Quad core on iMac

I am compressing HD footage down to SD dvd files so that i can put them on DVDs. I have all the batches running currently on my iMac 27'' 2.8 Quad Core.
When I look at the processor usage on iStat Pro, it says that I am only using 46% of my processor power.
Currently it is taking hours and hours to complete this project. And when I tested the video on my MBP Duel Core it processed at the same speed as the iMac. Something is wrong with this picture. Do i possibly need version 3.5...?
slfusion

No. looked for Clusters the other day, but figured i shouldn't waist my time if they just did what compressor does. Perhaps i should have searched deeper.

How much faster are the Quad-Core Macpros?

Does anyone have any idea how much quicker a Two 3.0GHz Quad-Core Intel Xeon will encode video in FCP, Compressor, and DVD SP, vs. a Two 3.0GHz Dual-Core Intel Xeon?
Thanks.

in some areas motion in particular or exporting mpeg2 from fcp timeline, is slower on this 8 core than on the older dual2gig PPC. this machine has the Nvidea quadro FX4500 which one would hope is faster using motion but doesn't seem to be. that being said compressor rocks using temp Qmaster 4 instance like making 2 pass mpeg2 from a movie file, 90 min movie compressed in 40 min. photoshop and after effects rocks due to multiprocessor use and rendered timeline stuff though not always clean is much faster. having to render more than once and having to watch top to bottom from a QT export out of FCP ***** somedays. Over all it's worth it in my busy every day world

13" or 15" is the quad core i7 and additional graphics worth the added money

I am looking to replace my 2009 13.3 macbook pro that I've upgraded with a new retina model. Regardless of which model I get it will have the 1 TB storage and 16GB Ram so really my only debate if I want to pay for the additional screen size, secondary graphics processor, and quad core cpu. I use the system for personal use, web browsing, email, itunes, and I play world of warcraft. However I also use this system for business and run parallels with a widows 7 installation running autocad (2D only), ePlan, excel, Rockwell Automation RSLogix suite and RSNetworx, as well as Siemans WinCC HMI software that utilizes a SQL Database. It is not uncommon for me to have all of the windows side apps running at once with multiple windows of each open.
I know the quad processor and the additional graphics card are better than what is available on the 13" retina but I'm not sure if I will see the difference with my usage. Should I go all the way and get the 15" with the i7 2.6GHz Quad core or settle for the 13" with the i7 2.8GHz Dual core?

Hi eric,
In addition to the factors you mention (and yes, I think the dedicated GPU is significant), here are the GeekBench (the standard for measuring computer speed) scores for your two machines:
13" 7899
15" 13287
Thats a pretty big jump in performance, and yes you will notice it with most of the apps you mention, some more than others.

Is the mac mini server the same hardware as the other mac minis (except for the quad core i7 and dual hard drives) with different software or is it configured differently?

I have a mac mini with an i7 dual core processor. It is perceptably slower than my macbook pro with a quad core i7. Does the mac mini server have the same hardware configuation as the regular mac mini with server software or is the hardware different (aside from the i7 quad core and dual hard drives)? I want a mini with a quad core i7...

Your assumption is correct. The server does however only
have the Intel HD3000 graphics like the base model with
no option, at this time, for the discrete graphics chip. So,
depending on what you are using it for, that could be a deal
breaker. Remember that your MBP does have a discrete
graphics chip.
I have a 2011 Mini Server connected to a Thunderbolt display
that gets used as an engineering workstation and general
personal use (some photo editing, LP restoraton, general
internet browsing). You simply just not enable any of the
server services. I find the combination to work quite well
for my purposes. I also have a 13" 2.7 GHz i7 Macbook Pro
which is pretty much strictly for work. As far as CPU
power it is pretty much equivelent to your Mini. For the most
part I find the Mini does outperfom my MBP. I heavily use
Parallels and Windows7 virtual machines, so the more cores
the better.
So, If you do a lot of CPU intensive stuff that is multithreaded,
the Server may help. If it is graphics intensive and your software
heavily leaverages the GPU, you may actually take a hit on
performance.

2.0 GHz Intel Quad core i7 vs. 3.7 GHz Intel Duo Core i7 Processor: Why not make the Quad Core 3.7GHz?

I don't really understand processors, but is the 2.0GHz Quad Core i7 really a better processor in terms of performance? If it has 4 cores why not give it greater processing speed like 2.7 or 3.0 GHz?
I am asking because I am thinking about getting the high end Mac Mini, but I see that it's processor runs at 2.0GHz and the others in the line run at 2.5 and 2.7 respectively. Why is this?

I'm really oversimplifying here, but...
Let's just assume that each core runs at full speed all the time, the total performance of that processor would be the sum of the running totals of each core:
Duo Core i7 = 2 (cores) * 2.7 GHZ = 5.4 Ghz total processor power
Quad Core i5 = 4 (cores) * 2.0 GHZ = 8.0 Ghz
Like I said, oversimplified. But, you get the point. Not to mention, most apps still aren't optimized, so at a given time they only use a single core anyway. In this case, it'd be more beneficial to have more cores, since they would (hypothetically) be able to run more simultaneous processes (four vs. two in your case).
I gues the greater question is: what were you planning on using the mini for? Most CPUs go underutilized anyway, so you may be better off getting a 2.0, and maxing out your RAM and maybe adding a SSD. Those upgrades (the SSD especially) will result in a very noticeable increase in performance.

Can window size be adjusted? It goes off the bottom of my iMac screen.

I can't get to the tool adjustments or the bins because they are off the bottom of my iMac 21.5" screen. Can't reach the screen corner to adjust window size. Any remedy?

Drag the top left of your PSE Window down and to the left to shrink the size of the window, then reposition the window so now you can see the bottom right corner.

What is wrong with the top of my IMac screen?

Can see something under my 27"IMac screen ,I'm pretty sure it is not a burn because it has depth and perspective to it when i look at my screen from a different angle , it is almost like the pixels at the top of my screen ( under my status bar ) are transparent. can somebody hel
