  • using the iMac 27 inch mid 2011 as an external monitor with a PC via mini DisplayPort

    I find conflicting information via web search to be able to use my iMac 27 inches, mid-2011 as an external monitor with a PC. Is it possible to use the iMac as an external display via the Display Mode target between Thunderbolt port of the iMac with a PC equipped with a mini DisplayPort?

    Of course, I hear it's possible with the appropriate cable. But if it is not possible, I would like to know for sure.

  • 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!

  • 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

    Lee

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

  • update the iMac mid-2011 or buy a new one.

    Hi guys,.

    I have an iMac 21.5 "mid 2011 with 12 Gb RAM. I was wondering if it was a good idea to override this model (installation of an SSD, etc.) or buying a new iMac.

    I am not very happy with RAM soldered to the logic board of the new models 21.5 ". Load path Apple extra RAM too. Most users may not upgrade RAM or change SSDS by themselves, but, I'm a small part of those who like to modify and update my Mac, I like to do and not be restricted by a marketing strategy.

    However, what do you think?

    Looking at the price of new iMacs, I would setup an SSD and more RAM if your iMac runs correctly. You will save money, and this computer will last you a few years without glitches.

    However, if you feel that your iMac is not powerful enough for the tasks you do, go for a new iMac. As you say, Apple does not allow you to change anything (except installation RAM on iMac 27 inches), so buy the iMac with the amount of RAM and disk that meet your needs.

  • Use the iMac with bootcamp as a monitor

    Dear community,

    Currently, I use my windows desktop pc, and I would use my iMac (24 inch end 2010) as a second monitor. The iMac runs on bootcamp and the apple partition is unfortunately broken. This means that I can only use windows on my iMac. Now, I want to use the iMac as my second monitor. Should what cable I buy to make it work? And how do I use target mode on windows (can not enter my Mac partition...)? I'm a little worried about buying bad cables. If anyone knows how to solve this problem, I would greatly appreciate your help!

    Sorry for my English, if you don't understand something just ask me.

    Kind regards

    Hello

    I looked for an answer to my question and I'm not 100% clear, so I ask your help please.

    I have an iMac 21.5 "2010 middle which I want to connect to an iMac 21.5" 2011 mid (which I think the purchase) in order to have two screens. I know it can be done with these two models but the iMac 2010 has a Mini Displayport connector and the 2011 has a Thunderbolt connection, so I don't know if it's possible. I don't mind which screen is the main.

    In fact, it can be done from the mid 2010 21.5 "iMac doesn't have a Thunderbolt port. See the information in use your iMac as a display with the target - Apple Support Display Mode

  • 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?
