SUCCESS: Imac 27" Late-2013 Bootcamp to Windows 7

After one grueling day fighting with possibly every Bootcamp-related issue there is, I have finally installed Windows 7 on my brand new shiny iMac 27".
I have these threads to thank:
Boot Camp - Setup was unable to create a new system partition....from Windows install
1 Billion Other Threads on "Downloading Support Software"
Here's the story so far:
The first problem was Bootcamp hanging forever on 'Downloading Support Software'. This could either mean my USB wasn't formatted right, or my connection was slow period (it wasn't). Many threads advised to manually download Bootcamp 5 software instead, but they failed to explain what should I use it for. How am I supposed to run and install this, when Bootcamp Assistant can't even install Windows in the first place? I was an octopus flailing in the dark, with so many questions but so few answers, some which were clearly over-tech for me to implement.
Then, at the stroke of midnight, after combining solutions I read in many threads, I have came up with a single dummy guide which I hope is useful to everyone who's hating Bootcamp right now.
Note: This is for iMac 27" Late-2013 (Low end Spec), Yosemite OSX.
Things You Need:
1. BootCamp5.1.5640 (If you're using a different model, refer to table here.)
The idea is to "manually" download the files that Bootcamp Assistant couldn't, which is possibly why it was forever stuck on 'Downloading Support Software'. The manual part, I understood - what nobody explained, was what to do with this file after. So here was what I did:
After unzipping all the files into a single folder, I compressed them again into a DMG file, using Disk Utility. (New > Disk Image from Folder)
The file is then renamed as 'WindowsSupport.dmg". After this, go to YourMac/Library/Application Support/Bootcamp/ and drop the DMG file there. Make a backup of the Bootcamp files, as you don't want to download it again. (Thank you, Loner T, I see you everywhere, you were my saviour in this one).
2. A 8GB USB Stick or Ext Hard Drive
Here's something you should know before installing:
Windows 7: A 2.0 USB Flash Drive or HD, 2007 or earlier model. (The reason is because Windows 7 is not compatible with 3.0 USB sticks, which came out post 2008.) 8GB or higher.
Windows 8: Any 2.0/3.0 USB Flash Drive or HD, 8GB or higher. (Based on sources).
I wish someone had pointed this out to me earlier before I rushed out and bought a Kingston Traveler 3.0 USB. Le sigh. Well, now that you know, you can breathe a little easier knowing that you just saved yourself a potential issue + 4 hours of frustration. In the end, I managed to locate my sister's old HD (I used an old ext HD, 2006 model), deleted everything and will naturally apologize later.
1. REMOVE ALL USB/HD except for the one you're gonna install Windows on. Apparently, this is important as it'll avoid some glitch.
2. Open up Disk Utility, and erase/format your USB to FAT.
3. Open up Bootcamp Assistant, and check all three options. You can never skip 'Downloading Support Software' anyway.
4. BA will load, and when it hits 'DSS', it will prompt you for a confirmation to enter password. This will trigger that "WindowsSupport.dmg" file you just placed in the folder (it will disappear, and until now, I have no idea why. But apparently, it works, because for the first time, there was progress.) It sped up my download bar, although I still had to wait a bit. After a long while, it will proceed with SAVING SUPPORT SOFTWARE, and this is where you celebrate.
5. Go through the rest of the steps, and Mac will reboot, this time, with Windows Installation.
Windows Installation (Windows 7)
1. Click Install Windows Now.
2. You have the option of Upgrading Windows or Custom (Advanced) Install. Click Custom Advanced, then format Partition : Bootcamp.
3. This is where you pray : You either proceed with the rest of the installation, OR, you get stuck with 'Unable to create system partition...' Have a look at the thread above for solutions. I didn't run into any problems whatsoever.
You should be able to take it from here.
Considering that this whole process nearly made me vomit blood, I am so so happy at installing this, I think I may have been channeling my inner geek girl. HOORAY!!!
EPILOGUE: I have also successfully installed my PS3 Dual Shock Controller, and now, I'm playing a heck lot of Windows games on my Mac like a happy fangirl. It's ON!

Thank you for posting your success story and a concise guide. Glad to see another happy user.

PS3 connect to IMac 27 late 2013

I am considering purchase an Imac27 (late 2013), nevertheless due to lack of space I intend to connect the PS3 to be displayed the IMAC 27 late 2013
Questions:
1. Can IMAC 27 ( late 2013) be used as an PS3 display ?
2. If the answer to the first questions is yes, what type of adaptors/cables are needed to a sucessfull PS3/Imac connection
3. Can IMAC ( late 2013 version) display PS3 games without losing any resolution or image quality ?

I'm not sure of anything.
You're there and know or can look and see what the socket in you wall looks like. As you are in Italy I assumed your outlet looks like
or if grounded there will be three pins.
Your Mac seems to have this type of plug on it. The UPS you are showing does not have this type of socket.
If you're in Italy it would seem the best thing is to buy from an Italian for at least European distributor. They should know what you need and have it.

カーソルバグ mac OS 10.10.1 (YOSEMITE) / iMac(27inch, Late 2013) / Photoshop CS5・CS6

mac OSのバージョンをYOSEMITEにアップグレードしてから
Photoshop CS5・CS6に共通して出始めた症状なのですが
解決法が見つからず困っています。
【症状】
コピースタンプなどのペイント系のツールを使用する際、
カーソルのポインタが「ブラシサイズの表示」と「矢印表示」を
チカチカと交互に繰り返して表示してしまい、非常に作業がしづらい状況に。
※チカチカしている状態の画像を掲載したいのですが、

IMac 27" (late 2013) leave it on

Should I leave my iMac 27" (late 2013) on at all times or should I shut it down? This computer is for home use only.

Read the user manual that came w/your iMac on "sleep & shut down" instructions/recommendations.

Flex memory? or Dual Memory for my iMac 27" (Late 2013)

Hello there, I have an iMac 27" (late 2013) with standard memory of 8GB (2x4GB). I just bought a 16GB kit (2x8GB) DDR3 1600MHz. I was planing on putting the 2x4GB (8GB) memory cards to my MacBook Pro (Late 2012) which only has 4GB and of-course upgrading the iMac 27 to 16GB.
MY QUESTION really is the following: Which configuration should do a better performance for my iMac:
1. Leaving just the standard upgrade of 16GB (2x8GB) memory
OR
2. Since the iMac has 4 empty slots, upgrading with 16GB (2x8GB) PLUS the 4GB (2x2GB) from my MacBook totaling 20GB
Will the second option work? Will it perform better than first option? PLEASE HELP
THANK YOU!!

No, they don't all need to be the same size, but they must be installed as matched pairs. If you now have 8 GBs installed in two of the four slots, then install 16 GBs in the empty slots - two 8 GB modules. RAM must meet the Apple specs for your computer.
You will find good products at OWC, DataMem, or Crucial.

Best ups for my new imac 27" - late 2013?

have an imac 27" late 2013, can anybody suggest the best UPS for my Imac (and for india)

There is no "best", personally I have used an APC ES750 and have been very pleased. Things to look for are how many devices you intend to plug into the UPS, the computer, perhaps backup HD's etc.. Don't plug in items like printer, or other non essential devices. Other items to consider are how much battery life to you want with when the power does fail. Don't get caught up in the sine wave discussion, it's not essential not practical.

IMac 27" Late 2013 Wi Fi Log in Issue

Hello everyone,
I apologize if my questions have been asked in the past. I'm completely new to the Apple Mac OS. I bought a new iMac 27" in the middle of 2014 and use it about once or twice a week and have had no issues to-date. I'm still in the process of learning though so my use of it is limited to basic emailing, web browsing and Skype.
In the last 2 weeks I have had problems logging into my Wifi network at home. It would not log on even after I had reset the modem. After trying and rebooting my iMac 3-4 times it would finally do so without changing anything in the it. I'm not sure what is causing it, but thought I would ask here.
What would be causing the log in issue to my Wi Fi network?
Do I need to be concern with the findings in the Etre check?
Startup after logging in my password would take longer than usual...what would be causing it?
Here is the result from the Etre scan. I guess what concerns me is in red...and also if it shows the Wi Fi log in issue.
Thank you in advance for your help and advice.

Hi, Jiyujin.
Thank you for visiting Apple Support Communities.

IMac 27" late 2013 run an external monitor at 4K on 60Hz?

Hey,
Not entirely sure if it is possible to do either on OSx or on a Windows Bootcamp, but is it possible to run an
external monitor at 4K at 60Hz? The graphics chip is a GT 755M but I cannot find any information regarding this matter.
Any pointers would be great thanks.

Hello JHyde01,
Thanks for using Apple Support Communities.
If you want to use a 4K display with your Mac, the displays are limited to a Maximum of 50Hz on one specific model as shown below.
You can use 4K displays and Ultra HD TVs at the following resolutions and refresh rates via the built-in HDMI port.
3840 x 2160 at 30 Hz refresh rate
4096 x 2160 at 24 Hz refresh rate (mirroring is not supported at this resolution)
With OS X Mavericks v10.9.3 or later, the following DisplayPort displays are supported at their default using single-stream transport (SST) at 30Hz.
Sharp PN-K321
ASUS PQ321Q
Dell UP2414Q
Dell UP3214Q
Panasonic TC-L65WT600
With OS X Yosemite, you can use all of the above displays as well as the following:
LG 31MU97 4K display (at 30Hz or 50Hz)
Other Mac models do support MST displays at 60Hz as shown below.
MacBook Pro (Retina, 15-inch, Late 2013, Mac Pro (Late 2013), and iMac (Retina 5K, 27-inch, Late 2014) computers also support multi-stream transport (MST) displays at 60 Hz. If you use a 60Hz MST display with the MacBook Pro (Retina, 15-inch, Late 2013) or iMac (Retina 5K, 27-inch, Late 2014), only one additional Thunderbolt display can be supported.

Can I install Windows (7) on my iMac SSD (late 2013) ?

I'm about to take delivery of my new iMac (late 2013) with the following specs :
27-inch Core i7 3.5 GHz with 16gb RAM
256 GB flash storage (pure SSD, NOT Fusion)
I've googled and found that some say that Windows cannot be installed on the Fusion Drive due to the Fusion Drive containing an SSD portion.
I would like to install Windows 7 - is this possible to install on the 256 GB flash (SSD) drive ? I'm not buying a Fusion Drive with this iMac, just a pure 256 GB SSD/flash drive. Or must I install Windows on another separate, non-SSD drive ?
Sorry if the quesiton is too novice or dumb. Thanks.

Unless you do high end gaming or very intense
3D graphics work, it will be much easier to simply
install a product like VMWare Fusion
(http://www.vmware.com/products/fusion/) or
Parallels Desktop Mac
(http://www.parallels.com/products/desktop/)
and create a virtual machine. Read up on these sites
to understand how a virtual machine works.
The advantage of this approach, the "PC" simply runs
as another window in OSX. No rebooting required.
If you really need the full performance of the iMac's
graphics for your Windows use, you can dual boot
by creating a new partition on the drive via Bootcamp
and install windows there. (http://www.apple.com/support/bootcamp/).
Be for warned, only Win7 and Win8 are supported by this
method.

Mac Pro Late 2013 USB problems / freezing

I have a quad-core CPU Mac Pro late 2013 (Model Identifier: MacPro6,1). MacOS X 10.9.5.
I have had all sorts of USB devices hooked up to it. At any one time, I usually have all 4 ports filled. I have a 3TB USB 3.0 disk that stores my large files, a USB mouse and keyboard (logitech with a usb mini dongle), a cable to charge my logitech USB cordless mouse, Lightning cable to my iPhone 5, and other things that I rotate in and out, like CF card reader, Audio Box USB audio interface from PreSonus, Sony Webcam, etc.
About 3 months into having the Mac Pro, I noticed that my keyboard went dead in the middle of using it. The mouse was dead too. I blamed the RF dongle that they both share, because the Apple Magic Trackpad (bluetooth) I have still functioned. Try as I might, I couldn't get the keyboard or mouse to work again, so I used the Magic Trackpad to restart the machine, and then my keyboard and mouse worked again.
It wasn't until later that I realized that all the USB busses on the machine had frozen or "died" temporarily. I realized it later because my USB hard drive complained about being "ejected improperly."
Now I have had the USB die on the Mac Pro at least 15 times over the last month and a half. Usually once every two days or so.
I have tried (almost one by one) using some of the USB devices on the mac, and removing others to ascertain if it's a certain USB device that is causing this. But the odd thing is that I never get a message from the OS like "xxx USB device is drawing too much power."
I'm going a little nuts here because I cannot see any rhyme or reason to the USB interface lock ups. And each time it happens, all the USB devices go dead until I restart. Sometimes, I'm able to SSH into the machine from my iPhone and issue a "shutdown -h now" and even though I see the Mac OS X UI shutdown, it never fully halts. I often have to hold the power button to get the machine to turn off.
I really can't say if it's software related, hardware related or what. I've tried to watch my workflow carefully to see if anything seems to make a pattern, but nothing yet.
Any suggestions? Is anyone else seeing behavior like this? Do we think it's a USB device... or is my Mac Pro flakey?
Thanks!

I was using a hub, so I immediately removed that upon the first issues. But the USB has still frozen after the removal of the hub. The HD is a self powered G-Tech drive. I'll have to play around a bit more will all of your suggestions this weekend.
I woke up the computer just now to check the discussion, an am greeted with a notification from Mavericks that the "Disk Not Ejected Properly. (Eject disk before disconnecting or turning it off)" which the disk is still connected, and the usb seems to still work fine. In fact I was able to unplug the USB cable for the G-Tech HD, and then replug it in, everything reappeared fine. The USB bus was not frozen (this time).
But it's this kind of flakiness that has me coming and going. I haven't (yet) been able to identify whether the USB is the problem or the driver or a third thing I haven't figured out...
