    Hi Fid
    Your mac is fine but you need OS X 10.8 Mountain Lion or newer and your profile says you have OS X 10.7.5 Lion.  You need to get ML as a purchase from the app store as mirror is a new feature with that OS.
    The alternative is a third party app called airparrot.

  • I have a mid-2011 iMac running Mavericks. When I click restart the computer goes to a white screen with a spinning circle and does not go any further until I hold down the power button to turn it off. What do I do?

    Ok, sounds like the safe mode boot worked... You probably don't want to always be in safe mode though (some reduced functionality) so does it do a normal boot now? If not, you should then reboot into safe mode and run Disk Utility. Then select Macintosh HD on the left hand side, and click the Verify Disk button. If needed, it will ask you to Repair Disk. If there are errors found, Repair Disk again until there are none. Then try another normal boot and reply with result, wether good or bad.

  • Where did 30GB of unused space on my SSD main drive go?  I have a mid 2011 iMac that until yesterday had just 54GB of space occupied on the primary drive.  I imported 45 minutes of video from an SD card.  Could that have used up the space?

    I added an SSD to my 27" 2011 iMac.  Although Sahidus is absolutely correct, it is much easier to add an SSD replacing the optical drive, it wasn't that bad to add it using an entirely seperate cable using SATA-III.  To me it is worth the extra hassle to install a SATA-III SSD.  This is where you are going to get maximum performance.
    Although it appears complicated, if you go slow, the procedure to install an SSD drive isn't too bad.  It takes at most 3 hours, as long as you are prepared and have all the parts and tools.

    This describes how I did it.  Now I get awesome data performance from my iMac!
    I think the 21.5" may be more difficult to find where to place the SSD.  But im sure it is possible.  Just be creative.

    Freeing Up Space on The Hard Drive
      1. See Lion/Mountain Lion/Mavericks' Storage Display.
      2. You can remove data from your Home folder except for the /Home/Library/ folder.
      3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
      4. Get an external hard drive on which to store some of your files after which you can
          erase the data from your internal drive to free up space.
      5. Also see Freeing space on your Mac OS X startup disk.
      6. See Where did my Disk Space go?.
      7. See The Storage Display.
    You must Empty the Trash in order to recover the space they occupied on the hard drive.
    You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
    Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.

  • 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?

    Re
    extract from kb article
    PPPoE (where there is no router handling the PPPoE connection)
    No
    No
    Captive-Networks (where you click an "Agree" button to access the Internet)
    Yes
    No
    Proxies (where specific proxy servers must be configured in network preferences)
    No
    No
    Certificate-based authentication / 802.1x
    No
    No
    try check if you are in that case for your internet acces ?
    could be a firewall problem too , if is possible try desable firewall ( or any internet filter )
    no you can not see a wifi selection if you are wired ( using cable )
    by the way D key for AHT need to be pressed AFTER start up sound , and hold at min one minute
    HTH

  • HT1522 I have a mid 2011 iMac running Lion, and the remote seems not to work at all!

    Have been trying to pair my Apple Remote with my mid 2011 imac.
    Nothing doing, although if I go and try same remote with an older macbook, it works fine.Battery all fine too, have been checking via digital camera. Something on my iMac is preventing this remote form being seen (and yes I have disabled ir receiving on the laptom after testing it)
    any ideas?
    thanks for your time!!

  • I have a mid 2011 iMac with 2 thunderbolt ports that I have never been able to get to work.

    I purchased two Segate adapters and drives but if I can get them to run at all they will eventually freeze up the computer and I will have to reboot. I just tried them again today and the computer does not even see them.  Has anyone else had this problem and did you get it resolved. I took it to the Apple store once and as you would know after a system reset it worked I took it home and within an houre it froze up the system and I have not gotten it to work since.

    Take it back to the Apple Store and leave it there so that they can check it out for a couple of days at least with the disks.

  • 2011 iMac won't install Windows 7 in Boot Camp

    I'm attempting to install Windows 7 x64 on my 2011 (Thunderbolt) iMac via a burned, bootable DVD which was previously used to install Windows 7 x64 on my friend's MacBook Pro. Apparently, the disc works. After partitioning one of my internal drives in Boot Camp, downloading the drivers and stuff Apple provided, putting that stuff on a FAT-formated flash drive, then attempting to install Windows, the install fails. Well, it doesn't really fail. Before I'm even given the option of installing, right after clicking the "start setup" button in the Windows Installer, I get an error saying "No device drivers were found. Make sure that the installation media contains the correct drivers, and then click ok." I go to scan and browse the flash drive for the drivers which Apple provided, and I get the same message over and over again regardless of what I click. I ran Software Update before doing any of this, and I have also attempted to install the x32 version of Windows 7 as well, as to no avail. I would try burning the Apple-provided drivers and stuff to a CD or DVD, but obviously there is no way to insert such a disc into the drive since the Windows disc is already in.
    These are my computer's specs, if they matter:
    2011 Thunderbolt iMac
    2TB storage, partitioning 100GB for Windows
    3.4GHz i7 quad-core
    16GB RAM
    Radeon 6970 with 2GB VRAM
    ...attempting to install Windows 7 Home Premium (I think) x64 (or x32 if I have to)

    Update: I've successfully installed Windows by re-burning my Windows .iso image at 4x. The install went smoothly, but Windows is now unable to boot. After installing and going through its series of reboots, then fails to boot after restarting (after given the option to select what method of updating you want Windows to use).
    This is some of the stuff Windows says, on a black screen with white text, when the boot fails:
    mcfg 0x8ee39000 0x3c 0x8ee0f000 0x195000 0x3
    (insert a ton more of that ^ stuff)

    I've dug  through various archived forum postings in the programming bowels of the internet. Apparently there was/has been/is a known issue in which Macs refuse to boot Windows when the Mac in question has a 2TB hard drive. This is due to some GRUB issue or something.
    I have no idea what to do. I need Windows, and I'm quite sure no Genius appointment will help me solve this problem. So much for a Mac seamlessly running Windows via Boot Camp.

  • Did Mid-2011 iMac come with install disks?

    I bought a new iMac today, and I want to sell the old one. Should I have install disks? I don't remember getting any.
    How can I wipe the hard drive and install an OS without them?

    Click here and try using the Internet Recovery system. If it's not available on that Mac, you need disks; if it is, it can be used to erase the internal drive and install a fresh OS.

  • Upgrade Mid 2011 iMac 27'' Graphics Card?

    Hello all, and thanks in advance. I have a mid 2011 iMac 27'' and for work, I do a lot of film and effects editing. I have currently ordered more RAM but my newly updated programs require an Nvidia card with CUDA drivers for rendering. Is it possible to upgrade the graphics card in my mid 2011 iMac to a newer, faster card?

    Thanks for the quick response. I understand they are part of the logic board, and it appears that they weren't designed to be easily accessible, but is it even possible? With some risky work, could it be possible to place a new card in? Or is it designed so other cards won't even fit?

  • 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 a 2006 mac mini

    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]
    http://en.wikipedia.org/wiki/Macintosh_startup
    Thus it appears the Mini also has a hardware problem.
    Make an appointment at the Genius Bar of an Apple store. It is free.

  • Is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

    is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

    A Fusion Drive is not a RAID; it's a CoreStorage logical volume group. While it's technically possible to do as you suggest, there would be little or no benefit from it.

  • I have a new (mid) 2011 imac and want to transfer my old records to itunes but i dont know what usb turntable would be best for a new mac that would have compatible software for ripping to itunes?

    i have a mid 2011 i5 imac and i want to transfer my vinyl records to itunes but i dont know what usb turntable would be best for my imac that has compatible software for transfer to itunes

    Hallo,
    I use an Akai usb turntable with the Audacity sw delivered with it. To monitor during recording I also use the LineIn utility (all this on a Macbook Pro with Mavericks).
    It works fine, only the input volume of the usb audio port cannot be adjusted (at least I did not yet discover how to do it) and the volume of the music is lower than other music imported into iTunes from CD or iTunes store, but still acceptable.
    Success, Jean
