Can I update my mid 2011 iMac firmware if I am running Windows only?

I am only running Windows 7 on my iMac - I do not have MacOS installed anymore. I want to update the firmware on my iMac - is that still possible?

For the 2009 and 2010 27" iMacs there is the Kanex XD http://www.kanexlive.com/xd but it is not compatible with ThunderBolt iMacs as Kanex states in their Product FAQs.

How can i update my old 2006 iMac Intel core 2 duo running 10.6.8 to OSX Lion so that I can sync using iCloud with my newer devices? Mountain Lion is not an option for my older model and Lion is no longer available at App store.

Call Apple's online store's telesales agents: 1-800-MY-APPLE (1-800-692-7753) or Customer Service and Sales Support at 1-800-676-2775. For Lion you'll get a redemptions code via e-mail and need to DL from the Mac Apple Store (requires SL 10.6.6+).

How do I update firmware for mid 2011 iMac running Yosemite?

I tried the link in the Apple support pages, but it told me I need Lion to install it. I bought the computer used. It came with Mavericks and I updated to Yosemite. I don't have Lion or any way (or desire to) install it.

There is no update for the mid-2011 iMac firmware that will fix the fans running at high speed.
Only the OEM (original equipment manufacturer) Apple hard drives had the proprietary firmware designed to properly monitor the hard drive temperature.
So you have several possible solutions:
1. If the computer was sold to you with a warranty, rather than "AS IS", my first choice would be to force the seller to restore the computer to the condition it was represented to be in when you purchased it, with an OEM Apple 500GB drive that does not cause the fan problem. If they cannot or will not correct the problem, make them take it back and refund your money. Consumer advocates such as the Better Business Bureau can help you prepare a formal complaint against the seller, and perhaps lead to a successful resolution through arbitration, without hiring an attorney and filing a lawsuit.
2. If you bought the computer "AS IS", you'll have to attempt to repair the problem yourself:
A) Locate an exact replacement for the original OEM Apple hard drive with the proper firmware and install it on your own;
B) Purchase a 'compatibility kit'. OtherWorldComputing www.macsales.com reverse-engineered a solution to the problem and sells a short cable with an external temperature sensor for the hard drive that can be used successfully with non-OEM drives. http://eshop.macsales.com/item/OWC/DIDIMACHDD11/
They also sell the sensor cable with a toolkit that can be used to disassemble and install the cable. http://eshop.macsales.com/item/OWC/DIYIMACHDD11/
C) Try the fan control program mentioned in earlier replies.

Maximum RAM upgrade possible on a mid 2011 iMac 27"

Can I upgrade my mid 2011 Imac 27" to 32 gb of RAM. Apple handbook says only possible to upgrade to 16gm (4x 4gb cards). Has anyone upgraded a 2011 Imac 27" to 32gb of RAM?

Yes, both OWC, http://www.macsales.com and Crucial, http://www.crucial.com offer 32 GB ram kits that are guaranteed to work...to do that you would be best to not buy from sources that are not Mac specialists and who guarantee their ram to work.

Cannot upgrade Thunderbolt firmware on mid-2011 iMac

Hi - I'm having problems updating the Thunderbolt firmware on my mid-2011 iMac (21.5").
Can anyone point me to the proper location for this firmware download? I've found several on the site, but none seem to work for me, due to a variety of OS incompatibilities.
For the curious, here's what my system says:
Hardware Overview:
Model Name: iMac
Model Identifier: iMac12,1

And here are the error messages from a variety of firmware update locations:
Thunderbolt Firmware Update v1.2
First error: The package was signed with a certificate that has expired (c'mon Apple!)... Do you want to continue with the installation anyway? (yes!)
Second error: Alert: This software is not supported on your system. (any reason why? OS, old other firmware, what?)
I've tried the tricks of PRAM and SMC resets, moved the com.apple.SoftwareUpdate.plist to the desktop and rebooted, etc., etc., but nothing seems to work.
The issue driving this exploration is that the Thunderbolt port appears to be dead - won't support Target Desktop Mode or the Thunderbolt Gigabit Ethernet adapter.
Thanks in advance for any help!

From that very page, it appears that this model does support Target Display Mode - please see the bold text below.
Am I reading it incorrectly?
Thanks for your help here - it's good to have more than 1 set of eyes looking at this!

Is there a way to run a 2005 PreSonus Firebox(with the firewire) to a mid-2011 iMac 0SX 10.7.2? It says its no longer supporting Power PC? Anything I can do without spending more money on new equipment or a new computer? Please help me.

Nevermind, I got it working.
I ended up extracting the new vob within MPEG Streamclip, which gave me an m2v and an aiff audio. I multiplexed those two back together in FFMpegX which gave me a complete VIDEO_TS folder with BUP and IFO files I needed.

THank you very much, I I have a ton of Adobe programs on my mac and i think a Cuda driver update was installed with it, it just popped up the other day in my system settings and is asking to upgrade my graphics card, but i don't have the same card as this update... so i thought i would double check! thank you again.

I have an 21.5 Mid 2011 iMac and i want to upgrade my RAM. Currently I have two 2GB and two free slots. Do I have to put in two 2GB in the free slots or can I use two 4GB or 8GB?

You can leave the existing RAM in their current slots and add compatible modules in the empty slots. For best performance, add two of teh same size. Our 2010 iMac 21" shipped with 4GB RAM---two 2GB modules in two of the four slots. I added two 2GB modules to the empty slots and now have 8 GB RAM.
Be sure to order RAM from a trusted Mac-savvy RAM vendor. Some vendors thing a Mac is a hamburger. For over a decade I've bought all our Mac RAM (and we have 18 Macs in teh family!) from one vendor:

My Mid-2011 iMac with pre-installed Lion can't load AHT (Apple Hardware Test) over internet

I have a Mid-2011 iMac (3.4GHz) of which Apple's Support document for the Apple Hardware Test (http://support.apple.com/kb/ht1509) says:
Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.
Well, this doesn't work for me. My Mac is on a DHCP-supporting router which has constant internet connection. Yet, when I turn off the Mac and then on again, holding the D key down even before the screen turns on, the Mac does indeed react to this key as it's then turning the screen on and taking another about half minute before it continues with the boot process along with showing the Mac symbol. Without the D, the Mac symbol comes up quickly.
So, it appears that the iMac is indeed trying to get AHT over the internet. Just that it doesn't succeed in it, and probably timing out after a while.
Any suggestions how to fix this?

What system did my 'Mid 2011' iMac come with?

I have upgraded to Mountain Lion but I'm wondering if the system actually came with Lion or Snow Leopard?

mulgravebrad wrote:
A friend has asked if he buys the machine can he reinstall Snow Leopard on it?
Good question. The Mid 2011 iMac can run Mac OS X Snow Leopard without any problem, but there's a problem: you need a special Snow Leopard version that it's only available on the Mac OS X DVD that Mid 2011 iMacs have got.
If your friend tries to call Apple to try to get DVDs for a Mid 2011 iMac, Apple will ask him/her for the serial number of the iMac. As your iMac came with Lion, Apple won't send him/her the DVDs he/she needs to install Mac OS X.
In conclusion, it's possible to install Snow Leopard, but things like a possible firmware restriction and the lack of the Snow Leopard version that your iMac needs may trun this into a very difficult task

Mid 2011 imac hard drive replacement

I have a mid 2011 IMac with broken 500GB hard drive. Due to Apple firmware built into the hard drive to test the temp. reading, I must use Apple brand hard drive unless I purchase OWC's temp sensor and use OEM hard drives on the market. I rather use Apple brand and can easily get one on EBay. Can I use an Apple brand hard drive specifically made for 2013 IMacs on 2011 IMac? I assume they both have same type temp. sensors and Apple firmware built in. Latter is also better as it supports SATA 3 standard with 6GB transfer rates.
Mid 2011 IMac hard drive model:
Seagate 655-1565D SATA 2
2013 IMac hard drive model:
Western Digital 655-1830A SATA 3

Mine came with this one, but I don't think you'll get one with the appropriate temp sensor from anyone other than Apple or an Apple approved service station.

i have a 27in mid 2011 iMac and i have been given a 2006 mac mini i have no screen to see whats going on on the mini and there is no os onboard how do i get OS X on to the mini so i can get to use this with a tv with hdmi i have the mini dvi to vga connector and a vga to hdmi lead into a samsung 32in led tv, tv keeps saying not connected???

- You said "Apple dvi to via converter with a via to hdmi cable . What is a "via"? I think you mean VGA.
Just what VGA to HDMI cable to you have? VGA is analogue while HDMI is digital. The Mini DVi out is both analogue and digital (DVI-AD). You would need a converter to convert the analogue VGA to digital.
- Yes, when you boot up you should get a chime if the Mac is functional. The chime The sound indicates that diagnostic tests run immediately at startup have found no hardware or fundamental software problems.[1]

Thus it appears the Mini also has a hardware problem.

How do I restore my 27" mid-2011 iMac EXACTLY the way it was after hard disk replacement?

Hi all.
Recently received an email from Apple saying that the 1TB Seagate hard drive in my 27" mid-2011 iMac is apt to fail anytime. Apparently they used some bad hard drives in the mid-2011 27" iMacs which are problematic so they're offering me a free replacement to a brand new hard drive. I'll be sending in my iMac for the replacement sometime in the next few days.
In preparation for it, I've backed up my entire system using Time Machine into an external harddrive. The backup is up to date & includes all system files. I've also made a Lion install disk on an 8GB USB flash/pen drive using Carbon Copy Cloner.
My question is: When I get my iMac back after the hard disk replacement, will I be able to restore my iMac to EXACTLY the way it was before the replacement using the Time Machine backup & the Lion install disk that I've prepared? When I mean EXACTLY, I do mean EXACTLY, e.g I don't have to re-install all the programs I have, my settings for the programs I have will stay intact, everything is where it should be etc...i.e EXACTLY the way my iMac is right now.
If yes, how do I do it? I've read Pondini's guide: http://pondini.org/TM/14.html
However it is less than clear on certain points, e.g in my case, which one do I have to use to restore my system to the way it was...the Time Machine backups I have on the external HDD or the Lion install disk that I made using Carbon Copy Cloner? And how do I go about doing the restore?
I'd appreciate any & all help given. Thanks in advance!

baltwo: Thanks for your input! I didn't think of wiping the old HDD before sending it in for the replacement..all those sensitive user data! One question: What's a FWHD?
Already answered. Just note that FW is much faster than USB. See http://help.bombich.com/kb/troubleshooting/how-long-should-the-clone-or-backup-t ake for details.
I already have CCC installed so I'll probably try it out. Are the steps outline here the one that I should do to restore the CCC clone when I get my Mac with the new HDD back? See: http://help.bombich.com/kb/overview/restoring-data-from-your-backup#full_volume_ restore
Yes.
Another question: while I'm booted on the backup/clone, and just after I've wiped the old HDD, how do I reinstall the OS to create a generic user account? Will I have to use a Lion install USB disk?
No. IIRC (if I remember correctly), you can either use a saved Lion installer (hopefully it exists on your backup/clone) or use the Recovery HD. If you have the USB stick w/Lion installer on it, use that.
