Unable to install Yosemite on mid 2011 iMac 27"

OK, so I have tried to install Yosemite on this mid 2011 iMac for two days now and I get the exact same error message every time:
An error occured when extracting files from the archive AdditionalSpeechVoices.pkg. Abort the installation and reboot.
I have formatted the harddrive, reinstalled the original OS using the Restore via Internet option (the Mac works perfectly with Mac OS X 10.7.X) and then I try to upgrade to Yosemite via App Store and the error is back.
Any ideas regarding what might cause this problem?
TIA

Unable to install Yosemite on my 2011 Macbook Pro (4gb Ram, 2.4 Ghz intel core 2 duo) machine.

Hello People,
I have been trying to download and install the new Mac Os Yosemite on my 2011 macbook pro which was previously running Snow Leopard 10.6.8. But, for some reason I am not able to install the file even when the download has been completed. This is the message i see every time i try to do a 'retry'. Can anybody please tell me whats going on with the installation process. and how can I fix this problem.

Your model uses:
Maximum Memory
8.0 GB
Memory Slots
2 - 204-pin PC3-8500 (1066 MHz) DDR3 SO-DIMM
So the specifications you provided will not work in your computer. Nor will your computer support 16 GBs.
A MBP 7,1 is a Mid-2010 model, not an Early 2011 model. If you truly have an Early 2011 model then it requires:
Maximum Memory
16 GB (Actual) 8 GB (Apple)
Memory Slots
2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
The specs you provided are also not suitable.

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.

Re-Installing Snow Leopard on a mid 2011 iMac

I have accidentally wiped the hard drive of a mid 2011 imac 27" there was no install DVD provided for this machine and a retail Snow Leopard disk will not boot, apparently I need 10.6.8 and the retail disk is only 10.6.3 is there any solution to this dilemma?

The machines (we have more then one) all came with SL but no install disks. When I boot with cmd-R it comes up with a globe icon and message - apple.com/support - 6002F. I am now convinced that these machines were so close to the Lion release and were probably intended for Lion but were shipped with SL. I have now tried everthing including Lion install from USB recovery stick created an another SL to Lion machine and this works to the point where after downloading all 3GB of Lion it just goes back to the beginning again! I tried 3 times - good thing we have fast broadband and it failed every time! I then tried restoring a SL and even a Lion clone from another similar Mac but kernel panic every time, tomorrow I will try the retail "Lion on USB" option but it looks like its off for repair as far as this MAC is concerned.

Hi, FaceTime on my mid 2011 iMac running Yosemite 10.10.2.

Hi, FaceTime on my mid 2011 iMac running Yosemite 10.10.2. I have contacts some of which only show option for audio FaceTime, on my iPhone an iPad the same contacts are available for video. Anyone know why, I can video some contacts from my iMac - but not others. The contacts are all synced via iCloud and the audio FaceTime from the iMac works fine to them but the video option is greyed out. If I go to my iPhone or iPad - there they are all ready to receive video. Curious. Anyone have any ideas i have exhausted the web searching.

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?

Sudden restarts while using bootable USB installer (mid-2011 iMac) - evidence of hardware problem?

Greetings:
For a couple of years I've been suffering from an issue reported in many threads: seemingly random shutdowns and restarts of my mid-2011 iMac. These can happen several times a day, or there can be a gap of weeks between occurences. I've searched the web and discussions.apple.com endlessly, and tried every conceivable solution. I've observed no consistent pre-restart pattern in Console. I've tried removing all unnecessary extensions and start-up programs. Fixed permissions, repaired HDD, many of the diagnostic procedures described by LINC (superuser on this forum). I would sometimes get temporary relief from periodic restart loops, by unplugging the computer and resetting PRAM, but this would not last long. I couldn't discern whether it is a software/conflict issue, or a hardware issue. Have run AHT in extended looping mode, several times, and found nothing wrong. Which caused me to keep thinking it must be a software issue. The last thing I've tried is a clean install of Yosemite, with full HDD erase, from bootable USB.
I did this successfully, restored files from Time Machine...but then a few hours later, a series of sudden restarts began, with 4 or 5 within a couple of hours. I decided to shutdown and restart using the bootable USB installer again, and run Disk Utility from it to check the HDD for errors.
But then, while booted up from the USB (and after running Disk Utility with a normal result): the computer suddenly turned off and restarted! And then it rebooted again into installer mode (i.e. running off the bootable USB), and I ran Disk Utility again and ...it happened again!
So what does this tell me? I am asking all of you for confirmation please. I am thinking this is a strong indication that whatever the issue is causing the restarts, it is hardware based, as the system was running off the bootable USB at the time, NOT using installed operating system or software. AND this reminded me of one other instance where the system had rebooted randomly, while I was in SAFE mode.
Would you agree that this is likely now pointing to a hardware issue? Is power supply the likely culprit? Or?? (and recalling that repeated AHT have showed nothing...). Is it worth trying to fix (out of warranty)?
thanks for any insights,
Warren

Mid 2011 iMac continuity issues!

I have recently upgraded to OS X Yosemite on my Mid 2011 iMac, but continuity doesn't seem to work on it. Is my iMac to old?

I did install Yosemite in my 27" iMac (Mid 2011) last Friday and after 6 hours of use I got display issues. After the iMac comes back from sleep I get pixelated blocks in random areas that stay on background until open a new app window. Two days ago my computer frozen and got pixelated blocks all over the screen. After restart got the graphics problem box and asked me to report it which I did. I restored Mavericks from my time machine and everything was working fine again. Then yesterday afternoon did a Yosemite clean install in my iMac and this morning got the same display issues and computer completely frozen. I restored Mavericks AGAIN and everything is working fine so far!!! I'm gonna stay with Mavericks until Apple release a fix for my issue.

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.

Mid-2011 iMac won't boot Win 8.1 (BC) w/ ACD 30 attached

I have a 27" mid-2011 iMac Core i7 with two external displays, an ACD 30" and a 20" HP. I spent a great deal of time watching Win 8.1 in a reboot loop after install (Apple Drivers installed fine), sometimes with vertical lines down the ACD 30 (nothing on the HP). (I didnt expect Win to notice the more than one DisplayPort screen.) Finally I disconnected the displays and I booted into 8.1 fine.
IS this a thing? Others share this experience?
Thats not the end of my Boot Camp woes, but that's all tied to this issue.

Can you provide details on how each these displays are connected?
From iMac (27-inch, Mid 2011) - Technical Specifications, you have two TB ports, which can support DP connections.

How do I migrate data from my 2003 iMac to my mid-2011 iMac?

Hi All,
I have a 2003 iMac and I want to migrate the iTunes, iPhoto, etc DBs to my new mid-2011 iMac. The 2003 iMac is the last one before they switched to the intel chip. It's Mac OS is version 10.5.4. That's as late as I can get it as they quit supporting the old chip after that.
I found a vid on mac-to-mac file migration online. It said to connect the two computers via firewire cable (done), start the new computer (done), start the old computer while holding down the T-key (done), and the old computer's hard drive will show up on the new computer finder window (did happen). Then it says to start Migration Assistant on the new computer (done), and follow directions. That's where I run into a problem. The Migration Assistant says "Looking for other computers" and it never finds the old iMac even though the old iMac's hard drive is visible in the new iMac's finder window. Note that I can click down through directories on the old iMac in the new iMac's finder window.
Any suggestions you can offer would be greatly appreciated.
Thanks much!

Your old machine may too old for Migration Assistant to work. In that case your best bet is to set up the old machine in Target Disk Mode and then drag and drop your files to the new machine. You should only migrate data files, if you have applications on the old machine these should be manually installed on the new machine. If any of the old machine's apps are PPC (Power PC) based these will not run in Lion and will need to be upgraded or replaced prior to installing on the new machine. You can check what apps are PPC based by opening System Profiler (Applications - Utilities - System Profiler), click Applications on the left and then look in the Kind column. Applications that will run in Lion OK are Intel & Universal apps.

PC Games and peripherals on Windows 7 on Lion on mid-2011 iMac. Possible?

Sorry for the long marquee, but I want to get anecdotal-experience answers on this convoluted subject before I waste a couple months of my fairly-rapidly-closing life --carpe diem. all y'all -- on something that's doomed from the very start.
For reasons I can't quite fathom (relative installed population, maybe), there are very few racing sims -- none, as far as I'm concerned -- for the Mac. That's most def not true for the PC -- I've been a Mac-only user since 1989, but the PC has always been -- when working -- a pretty good gaming platform (ALL it's good for AFAIC), with tons of titles, and the ability to accomodate multi, MULTI-axis controllers, like force-feedback steering wheels with gas, brake, and clutch pedals, and gearshift. I know of nothing like that for the Mac, even if there were racing sims that would run on a Mac.
So here's what I need to know: if I had a Boot Camp partition on my home drive (Macintosh HD), with a 32-bit or 64-bit (full version) of Windows 7 Home Premium, Windows 7 Professional, or Windows 7 Ultimate (necessary for my Mid-2011 27" iMac running Lion or above) installed on that partition, could I then install PC racing sims on that Boot Camp Windows 7-whatever Platform, and be able to use multi-axis controllers, like a Thrustmaster wheel, pedal, and shifter set?
Please, if anyone has been able to do this, by whatever means, on a mid-2011 iMac running OS X 10.7.x or above, I'd be eternally grateful if you could share your experience.
Thanks!
Bart

Seeing as how there are about 117 different versions of 64-bit Windows 7 out there, is there any particular version that is more advantageous -- in the case of Microsoft products, that means less bug-ridden -- for use on Boot Camp? I've seen reasonably priced ($66) versions like this:
"Microsoft Windows 7 Home Premium 64-bit FULL - BRANDED"
But then the description consists of this mangled English:
"This product will be branded HP, Dell, etc. but will do a FULL install on any brand computer and includes a DVD and COA. This is only unique to branded? [sic -- BB] OEM Windows products and not to non branded OEM Windows products. If you are the person people always seem to ask for help when their computer isnt right you should be fine with this. If you are not that kind of user you may want to stick to a non branded oem. Once again this only applies to Mac users [really sic -- BB]."
This is the only part of the description on this product page that even mentions "Mac users," and I'm left wondering if this "FULL - BRANDED" 64-bit version of Windows 7 will work OK on a Boot Camp partition on an OS X 10.7.x -- 10.8.x iMac.
Knowing all too well what a rat's-nest Windows has been since it was first foisted upon an unsuspecting public in 1985, with security problems that, after nearly 30 years, have still not been addressed, I want a 64-bit version of Win 7 that's going to give me the least amount of grief on my Boot Camp partition.
As this thread seems to be pretty much a dead letter, as many discussion threads become after an answer is provided, should I create a new question titled:
"Which 64-bit version of Windows 7 will work best on a Boot Camp partition on an OS X 10.7.x -- 10.8.x iMac?"
Thanks again!

Apple DVD player not working on Mid 2011 iMac running 10.7.2

I have a 21.5-inch, Mid 2011 iMac which came with Lion preinstalled. When I insert a DVD, Apple's DVD player comes up with the following error:
"A valid video device could not be found for playback. [-70017]"
The DVD player works. I can play DVDs using VLC, and I can use it to burn in iDVD, but Apple's own DVD player simply will not recognize it. I hoped this problem might be solved when I upgraded to 10.7.2, but alas it has not.
Does anyone know how to fix or work around this issue? This computer is used daily for my media-heavy job, so leaving it somewhere for service is not really feasible unless I'm completely unable to work on it.
