IMac 2011 windows 7/8 reserves 1816 MB ram for hardware

Hello,
I have an iMac 12,1.
When I install windows 7/8 on my iMac it says that 1816 MB is reserved for hardware.
A fresh install doesn't fix the problem.
The operating system is 32 bit.
It isn't a limitation from 32 bit because the limitation is 3.6 gb ram.
I can currently use 2.2 gb of my 4gb installed.
Opening msconfig and unchecking Maximum memory doesn't fix the problem.
Serial number: MC****X/A
Specifications: http://www.everymac.com/systems/apple/imac/specs/imac-core-i5-2.5-21-inch-alumin um-mid-2011-thunderbolt-specs.html

It is entirely the cause of the problem
512 mb video ram
And that is 512mb of the 1816mb that is reserved, If you check your memory structure I am sure you can find the rest.
Why you want to use 32bit software on a 64bit system is beyond me, but it is the cause of the problem.

Can i take RAM out of my old iMac (2008) and put it in my new iMac(2011)?

I added 2GB of RAM to my 2008 iMac. Can I add this to my new iMac (2011)? It came with 4GB of RAM.

Can you post your model identifier number on both please so we can pull up the specifications for both. You can find it by going to the apple, choose About this Mac, click on more info on the old Mac and System report on the new one; you'll find a window like this:
Please post that information (no serial # please).

Issues with 'stuck' keys on new iMac (2011) with Aluminium KB

Hi All,
I've got a weird issue which I've seen on a few other forums... with no real fix. I've got a new 27" iMac (2011) and I have been using it happily for a few weeks. In the last two days, my keyboard has been going a little crazy.
Firstly I thought it funny that the 'option' key wouldn't work during bootup and later I discovered that once booted in OSX, i'd have 'sticky' keys or keys not registering when pressed.
When I reset the keyboard, everything works fine again.
Its becoming a problem as I cannot register an of the bootup options anymore and have reverted to using an old Remote to access my boot volume screen (holding the Menu button).
Has anyone seen this before and if so, what is the fix other than taking the keyboard back to the Mac store?
Thanks again,
Con

Hi Cabakroll,
Yeah, I've been doing regular updates (when available). I have actually figured out the issue... its a very weird fix mind you. I went back to see what changed the other day, when I first notice the issue. I recalled that I swapped out the batteries (the ones that came with it were running low for some reason), with rechargables.
Since then, the keyboard has been going crazy. I swapped the rechargables with normal batteries and bingo, problem fixed. :S
Thanks for getting back to me though.
Hopefully this helps others too.

My iMac (2011) has been persistently throwing this error message: "SafariDAVClient quit unexpectedly." This started when I moved up to Mavericks, from Lion.

That's related since the process is attempting to load your Safari bookmarks from iCloud, and is crashing for some reason.
Try this:
Select the entire line that follows (triple-click to select it), then control-click, and from the contextual menu that appears, select Services > Reveal in Finder:
~/Library/Caches/com.apple.iCloudHelper
Drag that entire folder to the Desktop.
Quit Safari.
Attempt to open iCloud Preferences again. If it opens de-select Safari.
Launch Safari again and determine if the problem is fixed.

Cannot connect from iMac to Windows Home Server 2011 shares

Hi guys,
I am having dificulties connecting from iMac to Windows Home Server 2011 shares.
First of all it takes so long time to discover the share in iMac, which it's called "mediaserver". After finding it i cannot connect and gives "Connection Failed: message. If i choose "Connect As.." option i wait some time and then pops out with an error: "There was a problem connecting to the server "mediaserver". The server may not exist or it is unavailable at this time. Check the server name or IP address, check your network connection, and then try again."
If i try from Finder -> Go -> Connect to Server ... write in Server Address : smb://mediaserver it fails. But if i write the IP address, like: smb://192.168.1.42 it works after couple of tries. If i try now to Make an Alias for the share i get "The operation can't be completed. An unexpected error occurred (eror code -8060)."
Has anyone experienced these problems ? I have updated to Mac OS X version 10.7.3. Could that be the problem ?
Any help will be much appreciated.
Thank you in advance,
Simi

You need to reinstall the updated WHS connector for Mac. You should then be able to access your shares on WHS 2011.
The problem I'm having is I can't get Time Capsule to recognize the WHS 2011 mapped folders that show up on the desktop as a drive, so Backup won't work.

Problem logging off windows 7 on AD domain - Sound Card issue New model iMac 2011

I am looking for help for a strange problem we have on our new 21.5inch iMac computers (mid-2011 model), Our whole IT team have worked for a week to find solutions and we have exhausted all of our ideas. Please note we have an identical setup on our old mid-2010 model iMacs, which experience NONE of the same problems, windows logon and log offs are quick and painless. We have conducted side by side identical tests, so this forces us to assume it is a hardware/driver issue.
Basically our iMacs have BootCamp installed with Windows 7 Professional, Windows 7 is our default operating system. We have joined these computers to our Active Directory Domain and the users are all roaming with redirected folders.
The issue is the following: When a domain user logs off, it can take up to 25 minutes for the User Profile Session to finally log off and return to the normal Ctrl-Alt-Del menu, the next user who logs on usually is just left hanging and with no ability to logon. After a hard-restart the system logs on normally, but then can experience same problems at logoff.
We see the issue when the user watches lots of Flash Player videos on a browser such as Firefox and Chrome, although we've seen the same problem when other applications are used on the computer such as Windows Live Movie Maker.
So far we have found only one solution: If we disable the Cirrus Logic Audio Driver CS4206A (AB 9), and High Definition Audio Driver from the Sound, Video and Game Controllers within Device Manager and restart the computer, the system behaves normally, logon and log off times are a few seconds. But naturally we have no sound which is unacceptable.
We have tried everything we can think of including: Fresh installs of both OS, full updates of OS's, Firmware and Software, Manually updating sound drivers, changing users and AD Domains and attempts to force stop all services on logout etc.
We would appreciate any and all help to get to the bottom of this, including advice on what to try next.
Regards,
IT Project Manager
Tumo Project
www.tumo.org

Just wanted to feedback on this and say our solution was the following:
Download and installed Universal Driver Pack within Win 7 , which included a AMD High Definition Audio Driver and replaced the High Definition Audio Driver Installed.
I have also informed Apple and Microsoft of this issue, hopefully someone will take some notice and update the driver.

Has anyone tried driving two external monitors (3 total displays) on the iMac 2011 through the thunderbolt ports on Windows 7 Bootcamp?

I would love to purchase an iMac 2011 with the Thunderbolt ports, but I need to occasionally boot to Windows 7 Bootcamp.
I imagine this will work in general... but has anyone tried driving two external monitors using the Thunderbolt ports in Windows 7 Bootcamp?
Thanks in advance!
Ralph

Hi,
I am trying to get this working at the moment. both monitors are fine in Lion but I am losing the second monitor in windows. I will update you when I get it working.

I am feeling so ripped off right now. I have wanted a Mac for years and believed the hype about it's stability and I have had more trouble with this Imac 2011 than I have ever had with a pc. It locks up with several software products from APP store.

I am feeling so ripped off right now. I have wanted a Mac for years and believed the hype about it's stability and I have had more trouble with this Imac 2011 than I have ever had with a pc. It locks up with several software products from APP store. I have already had to have a technician to look at it and really couldn't figure out what the deal was. I was told that the APP store software should give me no problems but the truth is that it locks up on the software. This machine is only 4 weeks old and I am using 37 g on a 1 T hard drive. There is no reason for it to be locking up. Also, when I try to use the help program, it always tells me that I am not connected to the internet even though I have used both the mail program and the browser with no problem just before that. I successfully used the help program on my pc lots of times. I did not need a $2000. plus machine to just get email. I just wanted to unload on somebody that might understand my pain and after checking out this site...I think there is a few of you out there.

I was told that the APP store software should give me no problems but the truth is that it locks up on the software.
The apps downloaded from the Mac App Store are written by third party developers, not Apple. If you have problems with those apps you need to visit the support area for their websites. Launch the App Store, locate the app name. You should see a support link.

Go to ~/Library/Preferences. Move the com.apple.helpviewer.plist file from the Preferences folder to the Trash. Restart your Mac, try the Help menu.
If you need help finding that file, hold down the Finder icon in the Dock then click: New Finder Window. From the menu bar top of your screen click: Go > Go to Folder. Type this in exactly as you see it here: ~/Library/Preferences/com.apple.helpviewer.plist That will take you right to that file.
(.plist) files stores information about a particular app or in this case, the Help viewer. Often times deleting the .plist file resolves the issue.
It's fine to "unload"... we understand that you expect your iMac to be stable but there are times when things go awry. That's why we have these forums so that you can you get help.

I am running Snow Leopard 10.6.8 with bootcamp 3.3 on my Imac 2011. I need to updgrade to mountain lion. If I first upgrade to mountain lion, how do I go about upgrading from bootcamp 3.3 to latest bootcamp for mountain lion?

I am running Snow Leopard 10.6.8 with bootcamp 3.3 on my Imac 2011. I need to updgrade to mountain lion. If I first upgrade to mountain lion, how do I go about upgrading from bootcamp 3.3 to latest bootcamp for mountain lion?
I have seen a lot of discussions upgrading from Boot Camp 4 to 5 but no answers upgrading from boot camp 3.3 to 5. My worry is that if I upgrade from snow leopard to mountain lion, that my bootcamp partition will no longer be able to boot up. There seem to be a lot of threads suggesting problems that are possible. Has anyone gone through this upgrade with success?

Before doing any installation restart OSX from your 10.6 Snow Leopard DVD and use Disk Utility to Both Repair The Disk and Repair the Permissions of your Macintosh HD.
Next remove your Snow Leopard DVD and restart your iMac into OSX.
Update to the latest version of OS X Snow Leopard by clicking the Apple icon and choose Software Update to install Snow Leopard v10.6.8, the latest version.
Use Time Machine to make a Full Backup of your Macintosh HD.
Shut down and restart into Windows by holding the Option key at the chime and selecting Windows.
Now use Windows Backup to make a Full Image Backup of your Windows Installation to a removable drive.
Shut Down and Boot back into OSX.
Open the Mac App Store from your Dock to buy and download Mountain Lion. Then follow the onscreen instructions to install it.
Upgrading your OSX to 10.8 should not effect the Windows Partition at all since you are only upgrading the Mac side. You should not have to run the Boot Camp Assitant 5 Utility in OSX at all.
Your Boot Camp 3.3 Windows Support Drivers et. al only effect your Windows installation and should continue to run fine after upgrading.
Which version of Windows do you already have installed on the existing Boot Camp Partition?
Is it 32 bit or 64 bit?

IMac 2011 getting BSOD in Bootcamp

Hello all.
I installed Bootcamp on my new iMac (2011) and installed Windows 7 SP1. I downloaded the iMac drivers to a CD via Bootcamp, and installed this.
When I run Dawn of War 2 in Windows, I get the dreaded blue screen error with a "atikmpag.sys" error.
Now, I get that this has something to do with the Apple-drivers and the ATI-graphics, but what can I do about it?
I tried installing the ATI drivers from their web-site, but it says that my card is not supported.
How do I replace the Apple-drivers in Windows 7 with, say, ATI's own driver?
Thanks in advance.

It is an ATI driver, this is the info from Display Adapters under Device Manager:
Driver Provider: ATI Technologies Inc.
Driver Date: 07-07-2011
Driver Version: 8.872.0.0
Digital Signer: Microsoft Windows Hardware Compatibility Publisher
However, I did not download it from the ATI site. If I go to the ATI site and download the driver from there (after entering my hardware and OS info) it wont install. Says I don't have the proper hardware.
Instead, I downloaded the driver from here: http://www.hardwareheaven.com/mobility-radeon-drivers-support/206549-ati-mobilit y-catalyst-11-7-display-drivers-notebooks-27-07-2011-a.html
However, the issue is BACK! I played through several (10+) levels in DoW2 without any issues and exceptional performance, but then the game started freezing for several seconds, the screen turned either black or gray, and then the game went on - but just had a blue screen again.
Sorting the driver was my last idea, I am fresh out now.

What do I need to install win7 in my iMac 2011 21.5" ,and how much

I think all your answers can be addressed in a free session with an apple genius. All of your questions are about things that, as softwater points out, are free.
you have time machine already on your machine, hit command+spacebar and type time machine, hit enter. time machine will come up. Follow the steps it says to set it up.
Boot Camp (which I've never used) is also on your machine already. hit command+spacebar and then type Boot Camp. Hit enter. This is boot camp assistent. Use your CD of windows with this software and you'll be able to boot into windows 7.

No. Target Display Mode is not supported using Boot Camp and Windows 7 on a Thunderbolt capable iMac.
