• OSX Update 10.11.3 iMacs causes gray screen of death Mid 2011

  Hello everyone,

  I'm new to the forums of apple, so I don't know exactly if it was to go to the right place. This isn't any question that it's a PUBLIC service announcement.

  Basically, a summary of my post is that OSX update 10.11.3 causes both 27 "& 21.5" mid 2011 iMacs is not start properly. After the update installs and the iMac restarts, the startup sequence seems fine, showing the Apple logo, then the progress bar. However, when you expect your login screen to appear, instead you are greeted with a dark gray screen and movable mouse... and he the system is still a little sensitive. If you press the keys on the keyboard you hear the sound of "bum" as if you had to press a key when you weren't supposed to, and if you press the power button (do not want) the system will switch to standby (and wakes up if you press it again). So this isn't really frozen, it's just nice... it.

  Puzzled, I went to Google, hoping to find someone with a similar problem. I have not found much. I found some people with similar problems (gray screen is a bit more general), but I have found others with 27 "mid 2011 iMacs have this problem (links below :))

  Cannot install the update of El Capitan 10.11.3 (Stuck in gray screen)

  iMac mid 2011, gray screen of death!

  gray screen with the pointer to the login screen

  What I read, some iMacs have been recalled for the failures of graphics card, and that's what some people have responded to in the positions as a possible cause. (This is also what comes mainly from back when you search for "27" iMac screen gray) But this doesn't seem to be the issue here. The above posts are fairly recent and seem to coincide with the update 10.11.3 put in place, and they are the same symptoms that I have experience, but with no working solution.

  Once I have restore my backup time machine last before updating 10.11.3 is installed, the system works perfectly. Unfortunately, if you have not a backup time machine to restore, it seems that reinstall OS x is your only solution (until you reinstall the update)

  I'm not an expert of OSX, but I tried everything under the Sun to try to get the system to boot properly again, like resetting the PRAM & SMC , single-user mode, safe mode, none of this works. The system does not just start.

  I don't know if this has affected everyone with mid 2011 iMacs, but I just thought I'd let people with iMacs 2011 who are having problems with this update that you are not alone, and I hope that someone at apple can be seen. If you have an iMac 2011 that has not been updated to 10.11.3 again, I will not do.

  Thank you

  It is not material, it's software.

  My keyboard came with my Imac aluminum had a problem that I thought was material, but order the update of the post 10.11.2 v works again.

  Simply click near the center of the screen when it is grey and type your password.

• Work very well iMac 27 mid-2011 with 4MEM error code

  Hi, I have an iMac 27 inches, mid-2011 with 4 GB installed original (Elpida so-DIMM) so I improve it with 4 new 4 GB Kingston (ram value) KVR1333 PC3-10600 1333 Mhz DDR3 DIMMS for a total of 16 GB, after that my iMac works very well for three years with the daily use of any question and everything seems normal in "about this Mac" and in the "memory" tab no software issues no kernel panic , anything with a strange behavior, until three years after the upgrade memory, now I run AHT because the other reason (I can't work with a new MBP Mid 2012 airdrop both with El Capitan OS X) and it shows me a 64/4MEM/40000000: 0x8893cb98 error code, I reset the NVRAM and SMC, and same result AHT , so use MemTest86 from a V6.3.0 of bootable CD (full test upward at the end time spent 23 hours) and V4.3.7 showing no error in the two tests, also I ran mdsched.exe RAM Memory Sticks Checker windows (I have Windows 7 64 bit family Premium installed in bootcamp) and no ram detected error.

  While I should care that error? should I change my Ram modules?

  Thanks in advance

  You have a faulty memory card or the slot. That's what the error means generally. Make an appointment with the Apple Genius Bar for the service. If you need a Apple Store - find a store - Apple.

• Problem Windows/Bootcamp Partition with unsupported Mac (iMac 21.5 "mid-2011)

  I tried many door routes stealth to install Windows 10 on my iMac (21.5 inch, mid-2011; 1 TB SATA disk), which seems to be not taken in charge by Apple. Whenever I try to use Bootcamp to try to establish a partition, in the end it cuts and force restarts my computer.

  I decided to make my own (150 GB, FAT MS-DOS) partition and a bootable USB stick with all the files .iso on it. The bootable USB key works very well and can get into Boot EFI without problem. The score, according to the EFI boot and Windows Installer, "has a table of MBR partition...". [and] Windows can only be installed on GPT disks. »

  I tried to format the partition to NTFS by using the command-line Windows, such as proposed in the link below, but after downloading the Tuxera NTFS file to move the .iso to the Windows partition image file (I guess to make its own bootable drive) the drive itself is not started.

  In fact, the Windows partition came not in the start screen (hosting option after reboot OR allowing the computer initiate by itself).

  https://www.reddit.com/r/Mac/comments/3rzxd5/guide_windows_10_bootcamp_on_unsupp orted_macs.

  

  After trying to format this partition using the Windows command line, Windows begins to remove it and provides the same error message. After some research, I found that the partitions are hybrid and need for special maintenance. I tried to use gpart, but when trying to convert ONLY TPG, took place the message in a terminal:

  Caveat! Main partition table overlaps the first partition of 32 blocks!

  You need to remove this partition or resize in another utility.

  Caveat! Secondary partition table overlaps the last partition of

  33 blocks!

  You need to remove this partition or resize in another utility.

  I activated the command 'csrutil disable' in Recovery Mode in order to bypass the Protection of the integrity of the system, I found that some users of El Capitan were problems with this.

  I was not able to proceed to the question since this last error and I'm not sure how to proceed, especially because I don't want to lose my data on my Mac hard drive. If anyone knows any information on how I should proceed, please let me know!

  1. you use Boot EFI on a preUEFI computer.

  2. to help TO do a FAT32 partition will also create a hybrid MBR. Please after the release of

  sudo fdisk/dev/disk0

  3. you need not of Tuxera, because Windows install has already the ability to convert FAT to NTFS.

  4. your built-in optical drive works? If so, your W10 ISO burn to a physical DVD and try to follow the standard installation of the BCA.

• iMac 27 "mid-2011 - Intermittent problem with CPU fan running at full speed and sleep mode.

  Hello!

  My iMac 27 "has an intermittent problem with the CPU fan runs at full speed. Sometimes it happens at the time when I start it, sometimes only in my session, and sometimes only after a certain time. So does seem to be a problem of "heating".

  Second issue is with the mode 'sleep'. It may occur also at any time, at the start of the iMac, session, or after a certain time. But once he starts to go in mode 'sleep', when I wake up, it goes right back in mode after a few seconds and that it will continue indefinitely until I restart the computer.

  What could be?

• What is the problem with my iMac mid-2011

  Hello

  Need help find out what is the problem with my iMac to mid-2011.

  Yesterday during a reboot it just never came to life.

  On turning the power on, I get the RINGTONE to start and that's it. The screen is totally black. Nothing behind tried with a torch.

  VRAM rearmament so far I tried repeatedly, unplug and plug, all kinds of combinations of keys in the carillon and nothing.

  Connected to an external monitor and shows nothing of too - no signal.

  Any way that I can know what is wrong with it before sending it to the service tech? I suspect bad graphics card but how do you ensure?

  From what you describe, it looks like a hardware issue that Apple will only be able to resolve, but not to despair immediately.

  Read it please get help with graphics issues on external displays connected to your Mac - Apple Support.

  I know that the title and subject are not suitable to your concern, but buried in this document is the following passage that contains three links describing the steps to follow.

  If you can not change the resolution of your screen because you see no image, restart your Mac in safe mode to reset the default display resolution.

  If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

  That first, then write again for additional suggestions if you are still having problems.

• Update the iMac MID 2011 to work in FCPX with 4K

  Hi all

  I think to upgrade my iMac like mine is a MID 2011 but research on the Apple site, I don't think OMG that tilt for £2800!  My current system is an i7 3.4 GHz with 12 GB 1333 MHz RAM and AMD R HD6970M 2048 MB.
  I also installed an SSD as boot drive a few years so he tried there to justify going to the iMAC for 5K.

  Do you think I'll get a decent performance gain in FCPX edition 4K since the new iMAC
  4.0 GHz quad-core Intel Core i7, Turbo Boost up to 4.2 GHz
  32GB 1867 MHz DDR3
  2 TB disk Fusion
  AMD Radeon R9 M395X with 4 GB of video memory

  Thank you very much

  ID to avoid the car of Fusion. Rather get a smaller SSD and use an external RAID Thunderbolt.

• Safari does not open a window on el capitan 10.11.3 on iMac mid 2011

  What to do to 9.0.3 Safari that doesn't open new window not and loads slowly on el capitan 10.11.3 on an iMac 21.5 inch mid 2011?

  The problem is probably due to outdated software to OS X and Safari. The latest version of Safari available is 9.1. The last OS X for El Capitan is 10.4.11.

  Click on your Apple  menu at the top left of your screen.

  In the drop-down list, click: App Store

  When you load the App Store, select updates at the top of the window menu.

  Your Mac may restart several times during the update. That's ok.

  When it's done, try Safari.

• Hi all, I have an iMac (21.5 inch, mid 2011) with 4 memory slots, 2 has 2 GB each, is it OK to put a 4 GB in each of the empty slots or should I buy 4 new 4 GB and replace all, Sebastian Cheers

  Hi all, I have an iMac (21.5 inch, mid 2011) with 4 memory slots, 2 have a 2 GB each, is it OK to put a 4 GB in each of the empty slots or should I buy 4 new 4 GB and replace all, Sebastian Cheers

  You can put 2 x 4 GB DIMMS in the empty slots, this will give you a total of 12 GB. iMacs are very sensitive to the RAM, it is best to buy RAM from reliable sources like Crucial (direct purchase) or OWC OWC RAM

• 27 "mid 2011 iMac drive solid state drive is dead and must be replaced. Is this easier to do than to to replace a HDD with a SSD? I hope I can do it myself.

  My 27 "mid 2011 iMac drive solid state drive is dead and must be replaced. The SSD originally came with the computer and not a subsequent update. I understand that a SSD replacing a HARD drive is quite complex, but would be more simple replacement of a dead with a new SSD SSD? I hope I could make myself.

  Even as the replacement of a HARD drive. However, go to OWC buy the connector of the special drive that has the necessary temperature control that is not part of the SSD, because it is for the stock of HARD drive.
