Why is Best for Display setting in new iMac with Retina 5K Display only 2560 x 1440?

I just saw the new iMac with 5K Retina Display. It's awesome! I do have one question, though: The default (Best for Display) resolution is 2560 x 1440. That is the same as my current LED Cinema Display. Adjusting the scale in the System Preferences/Display settings maxes out at 3200 x1800, not 5120 x 2880. I'm not sure why the highest scale option isn't the full resolution of the display. Can anyone explain this or direct me to an article that does?

That got my curiosity too. It's something about the retinas pixel density per inch being higher than other displays, such as a Cinema HD.
The "Best (Retina)" option says "Looks like 2560 x 1440" when you roll over it, but the real pixel density is actually doubled I think, so 5120 x 2880.
The "Looks like..." phrase seems to refer to the size of elements on the screen rather than actual pixels. Perhaps that's what some folks call virtual pixels.

How noisy/quiet is new iMac with Retina 5K display?

How noisy/quiet is new 5K iMac compared to the standard display versions? I returned three 27" iMacs (3.5GHz Quad-core Intel Core i7) back in May because they were too noisy for me. Is this 5K machine any different?

imac 5k sadly has a very active fan, especially in the combination of i7 and the amd r9 m295x gpu (4gb).
check the forums (wow, cod etc.) where many people are currently complaining and returning their mac (me as well considering it).. while gaming the fan speed is at 2700 rpm which is around 38 db (very loud!) and the gpu is 105C (not fahrenheit!).
all processor (cpu) intensive tasks like handbrake, rendering etc. will make the i7 go warm and the fan go loud.
all graphics (gpu) intensive tasks like any game will make the amd m295x go hot and the fan go very loud.
regular surfing, photoshop etc. is not affected!
in normal mode, it's always at 1200 rpm where it is not audible to me.
if you want it as quiet as possible go with the i5 and the cheaper graphics card (290x).
just be aware that this is the loudest imac or even mac ever (louder than current mac pro) and I'm not sure if constant heat (105C) is affecting life expectancy and I've been having them since 1991.

New iMac with Retina display has attracted a group of ants. Why?

New iMac with Retina Display has attracted a group of ants to nest in it, while they ignore my old Macbook Pro. What is in the new laptop that attracts the ants? The Apple Support set me up with an appointment at an Apple Store and the Apple Store says it is Apple policy not to touch it with the Ants in it. Wasted 2.5 hours in travel time and in the store with no solution.

Its the electrical charges that attract them, they sense them as other critters to eat / talk with
the swarm of tiny DC power fields inside a computer, and the charges across the screen attract insects that have EM sensors on their exoskeletons. Its a come hither spotlight for insect critters.

If you want them out, which of course you do.......make a sugar trap for them.... a trail from the computer to a little pile. One screams the treasure to the others, .....they all come running, then you brush them away, or some other insidious method.

When support After Effects Ray-traced 3D the GPU of the new iMac with retina display (GPU: AMD Radeon R9 M295X 4GB)?

I would like to know whether After Effects CC Ray-traced 3D support the GPU of the new iMac with retina display.

It never will. This is nVidia-exclusive technology and the whole things is deprecated, anyway. You better learn to use Cineware, buy a 3D program like Pro Animator or Element 3D or learn a proper 3D program.

Does the iMac with Retina 5K Display have "user accessible" SO-DIMM slots or not?

The Apple Site "http://www.apple.com/imac-with-retina/specs/" for the iMac with Retina 5K Display states for memory that it has "four SO-DIMM slots, user accessible". What does that really mean? Contact with Apple support indicates that the newest iMac is sealed, therefore I MUST order it with all of the memory I need, or I would have to break the seal (tear it apart) to upgrade the memory later to get to the memory slots...there is no access door as there was in earlier iMacs. Is the memory in slots or soldered in? How can that be interpreted as "user accessible"? This seems very misleading, or Apple support has it wrong.
Sorry if this seems like a rant, but it sort of is. Does anyone know the facts on this?

The previous 27 inch iMacs had the same statement. It means that the user can access the memory slots and add or change ram. There is an access panel on the iMac. On 21 inch iMacs there is no door and the ram is not user accessible.

I have bought a Apple iMac with Retina 5K display! Can I use it with all my Adobe Creative Cloud

I have bought a Apple iMac with Retina 5K display yesterday! But today I read something negative about this Imac regarding to to Adobe Creative Cloud, - so I would ask if I can use this iMac with Retina 5K with all my Adobe Creative Cloud programs??
I have not unpack it yet, so I would be happy if you could tell me if I should keep it or exchange another Mac if this iMac with Retina 5K display does not work OK in Adobe Creative Cloud. I mostly use the programs Photoshop, Illustrator, InDesign, and Muse.
I look forward to hearing from you!

WOW!!
That was great to hear.
I have just read this tread: https://forums.adobe.com/thread/1626784?start=0&tstart=0
So therefore I was worry about Illustrator which I use most of all programs.
Thank you !!

What's the best way to set up new imac for logic etc?

In brief:
Getting new imac (27", 3.4 i7, 8-16GB ram, 1TB HD). Will be using it mainly to run Logic Studio (loads of plugins) and Final Cut Express. I also have 2 external Hard drives one 500G one 1TB.
The last imac I bought was my first and just went ahead and threw everything at it not really knowing where things should go. This time I want to set things up correctly.
Basically, with what I've got, what is the best way to set things up. I.e where do I put logic files, samples, BFD2, Amplitube etc. Where do I put videos for use in FCE. Storing projects and backups for use with Time Machine.
Also noticed the new imac will only have 1 firewire port. I will need to plug in the Hard drives (daisy chained), camera and RME Fireface 800. Was thinking of getting a Thunderbolt Hard drive but they are expensive and hard to find.
Would really appreciate any help before I get the new machine and start messing things up again.
Thanks.

Adding to babowa, enable the system firewall in System Preferences>Security>Firewall tab. Click Advanced and check Stealth Mode.
Lion is a pretty steady and secure operating system, and as there really aren't MANY Mac viruses, there ARE viruses out there still. OS X is pretty good about letting you know if you do accidently download a virus, and it will help you throw it away if it detects one, such as the MACDefender virus. OS X has built in security features such as sandboxing that doesn't allow viruses in as easily as a Windows PC. As for hackers, as long as you have the firewall enabled and a secure password (for your computer and email accounts), then you should be fine.
It's the user that lets the virus in, not the computer (unless there's some untold serious vulnerability in OS X, which is highly unlikely). Keep your apps up to date, don't download pirated software, and be street smart on the internet. Don't download things or visit websites that you don't think are real. Safari includes a Phishing feature that automatically detects known phishing sites, protecting you from that big problem. Keep your passwords secure and you should be fine.
There are antivirus solutions out there, one notable one available in the AppStore is Intego's VirusBarrier (free and plus versions), if you feel you still need one.
I wouldn't worry about it. Windows users who switch to Mac are always asking these questions.
Here's some good reading as well

I accidentally set up new iMac with wrong iCloud account. How do I switch it?

I had a .me account and an Apple ID using my email account. Got a new iMac and used the wrong one when I set it up. How can I switch to the correct Apple ID/account on my iMac (so it will sync with my iPhone etc.)?

Sign out (in System Preferences>iCloud) and then sign back in with the correct credentials.

Where is the 27-inch iMac with Retina 5K display built?

Is this computer built in the United States or somewhere else like China?

I'm not sure where it is assembled but I read somewhere that the flat panel is made by LG. Out of interest, does it matter?

My online purchase of new 21.5 IMac is scheduled for delivery to apple store for pickup tomorrow . I have purchased Apple one to one care. Do I need to schedule an appointment with apple genius on the day of pick up to bring in my old desk top computer to transfer and set up new IMac?

Usually I would think so.
Note, if your old Mac or any of your old applications are pre-2006, see this tip.

Otherwise the transfer may not be as smooth as you desire.

Do I need a screen protector for my New iPad with retina display?

I have a screen protector on my new iPad with retina display, but does this effect the screen display and do I really need a screen protector on?

So I just got my first ever iPad (4th gen) about 4 days ago. I am waitng on a case and have been looking into a screen protector, debating this same question on quality. I have a 3 year old and he is dying to play with it. In the meantime I cannot stress how careful I have been, as Im sure you all know what Im talking about. Last night I was using it on my lap and my shirt tugged it off, causing me to grab it before it fell. Of course the longest, sharpest nail, caught it for me. Obviously I freak out and hurry to clean the screen to see for damage. I see there is a huge line where my nail caught it, but upon cleaning was no longer there. This nail was sharper than any key I own! So I guess what im going to do is get a complete cover for use with my 3 year old and just a basic one when I use it. Good job apple!
