• Can I install 20 GB of Ram on my iMac 27 inch 2011

  I just upgraded my iMac 27 inch 2011 from 4 GB to 16 GB model. I installed two chips of 8GB. I can also install the 2 other 2 GB chips? Or is - better than for a total of 16 GB to 32 GB on this machine. Apple staff told me that it is not good to use too much Ram on my iMac, because it would be somehow the cause of the problems on the system.

  I am running OS X El Capitan.

  Thanks for your help.

  16 GB max is all that 2011 will focus on the iMac. It has 4 total slots but put the RAM in the empty slots will not do anything.

  See it-> https://support.apple.com/en-us/HT205040

• 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?

  Please help me!

  Hello! How to install windows 8.1 iMac (27 inch, mid 2011) without DVD drive and race El Capitan?

  I read everything I could on the subject and could not get the Boot Camp Assistant to create the USB key. Can you help me?

• Why my iMac (27 inch, mid 2011) cannot run Windows 10 in boot camp? And if he can't, he would work in something like parallels?

  Why my iMac (27 inch, mid 2011) cannot run Windows 10 in boot camp? And if he can't, he would work in something like parallels?

  To be honest, Windows 10 is compatible with your Mac, but Apple does not release from Windows 10 drivers for it. There are various guides on the Internet to install the drivers for Boot Camp Windows 10 even if your Mac is not supported, but follow them at your own risk (don't forget that you won't receive help to make).

  However, you are free to run Windows 10 on a virtual machine. To do this, you can use Parallels, VMware or VirtualBox, but remember that a virtual machine will give you less performance than Windows natively on your iMac. Read-> Windows in BootCamp or Virtual Machine?

• iMac 27 inch end 2012 unbootable

  This morning when I was working on my iMac 27-inch end 2012, suddenly he stops and does not start.

  After pressing the power button there is no sound and no display. NOTHING. BLACK SCREEN who knows what may be wrong...

  Hi Heinz, bad luck. This Apple support can help.

  Since you have no power, much of it does not apply. Read the subtopic, "power problems."

• iMac 27 "mid-2011 hard drive failed, fan to full after the removal of HARD drive

  iMac (27 inch, mid 2011)

  2.7 Ghz i5

  12 GB of RAM

  I have a fault where the HARD drive fan runs at max speed (RPM 5431, 51 * C temp).

  The first symptom was a rattling noise from the factory 1 TB HARD drive, which has disappeared from the system, to be replaced by a disk of 4 GB in size. Then the fan started running at max speed.

  A few months ago, I installed a 2nd drive HARD, an SSD and use this to all the data, so the 1 TB drive HARD original was basically unused and empty. To try and stop the fan and also run the disk diagnostics failed I've removed it from the iMac. However the HARD drive fan is always full.

  I ran the Apple Hardware Test and received the error message: 4SNS/1/40000000: TH00 - 9,000

  Given the primary SATA HDD is now removed, I also set the temperature probe? Are there other fixes to this problem of fan? I didn't intend on replacing the HARD disk immediately that this is not necessary at this stage.

  Thank you!

• record online audio on the iMac 27-inch with screen Retina 5 K?

  How can I record a quality online on my

  iMac 27-inch with screen Retina 5 K?

  Any suggestions?

  

  So from what I can tell the model have built in analog audio input, you would probably need some kind of third-party USB audio interface. You may be able to record in mono with a suitable adapter because the port is apparently compatible with Apple headphones for example.

  You could see the report on the system by the use of a utility rather

  Sometimes the quality of third party memory isn't at the height.

  Or part of 'close the number' is maybe not correct for the computer.

  In any case... good luck!
