iMac 27 "end 2013 - random stop

My iMac 27 "end of 2013 - have this problem to stop randomly, as power chord is out... randomly. I only can he start by plugging the power cable and wait for 5 minutes and then restarting it.

When I explored the forum it seems the problem until 2010, it is a shame that the problem persists on a such expensive iMac after all these years and apple is unable to provide a definitive solution.

My machine is less than a year, still under warranty, also under Apple Care, it took twice to the service center, here is the chronology of the events:

-They have reset the SMC, PRAM, re-installed OS during the first visit, the problem persisted

-Spent an hour on the phone support, yet once done a web-installation of the operating system, left ElCapitan to Yosemite, the problem persisted

-Took it once again, they have replaced the main Board... the problem still persists

I have read many theories online but no final solution. Here are some of the theories about what I found:
-RAM 16 GB the origin of the problem... but mine is 8 GB

-All slots of RAM is full... but mine has only 2 slots filled

-It happens that the i7... but mine is a machine of i5

-Could be because of the UPS, not having is not a good sinusoidal signal... wondering how to properly test it!

Someone has encountered this problem and solved definitely... Please help, as I am losing confidence with the ability to engineer Apple to fix it... Wow! This seems strange, isn't it, most innovative and most valuable world company is unable to fix a common issue that many customers are faced with... and we lose confidence with them.

I am in Bangalore in India, also need to check on the rights of consumers on this, any entries on this help because I think I deserve a replacement for the defective product. If it was the United States, if it is a lemon (take to solve the same problem 3 times)... even the cars is not replaced. Wonder how this works here. The lawyers on this forum?

Fellow fans of Apple and mac fans (I'm one too!) Please help.

Remove the UPS and test.

  • Problems with El Capitan on iMac 27 "end 2013

    Hello. I had some problems with my end 2013 27 "iMac. The majority of my problems seems to be turning around not being able to wake from its slumber unless I hard boot the system. I am running the operating system more recent 10.11.3

    Sleep problems have started with my installation of El Capitan. I have reset the PRAM the SMC and have disabled the hibernation and Energy Saver preferences are set to never spin down hard drives or screen saver. Problem persists.

    I also experience unexpected freezes. When these occur usually, audio on my system continues (if listening to iTunes or in a video game, the audio keeps going) but there is no response from the mouse or the movement on the screen at all. key board does not respond and mouse is frozen. The last time I had it's happen I had a panic the kernel to reboot (see below for the report)

    I tried everything I can think of. I've scoured the forums on the internet for help and support. Im not sure if this is hardware or software related. I tried to unplug all of my devices - I have several hard drives USB and Thunderbolt. I have a second monitor connected via the bolt of lightning as well. This could be a video card problem?

    I have used the EtreCheck software and have gotten several things that make me wonder if it's the software however, it seems that somewhere I still have pieces of teamviewer lingering around, even if I had uninstalled the software and I can't find anything in the spotlight for her. Here is an excerpt of my report...

    Some things I noticed - I had questions on shut down the system. My computer completely sometimes turns. I have to force quit the finder or the dock still will remain open and prevent the closing down. If this happens, then I need hard closed by pushing the power button until the device turns off. My system is INCREDIBLY slow sometimes since the upgrade as well at el capitan.

    I had a few problems with the big Adobe applications as well - sometimes illustrator or photoshop does any open or apps say they are open in the dock and in the force to quit smoking, but do not show in the activity monitor. In this case I have to restart my system for most work. force quit does not help them.

    Sorry for the long post, but I have worked on Macs since OS7 and even worked in an apple store genius bar for awhile so I generally know what I can do to fix these but I can't get it probably remain fixed. I thought better to have as much information as possible. My next step is to reload the entire OS, but I have a lot of work here that I'm afraid to lose (even though I have several back ups via time machine and other copies on external drives)

    Any help and advice would be most appreciated!

    Thank you!

    Hi Joel,

    • What version of Photoshop installed on your computer?
    • Also, please go to the Photoshop preferences, then the performance tab.
    • Here please click Advanced under 'Use Graphics Processor' settings and change the mode of drawing on 'Basic '.
    • Also uncheck "Open CL"
    • Restart Photoshop and then try to open an image and see for the boxes.

    Let me know if it helps.

    Kind regards

  • iMac 27 freezing at random, leaving weird video on screen

    I'm having a problem with my Imac end 2013.

    For the last week or two, he has been randomly freezing upwards. The display freezes just upward to let appear an odd of the fragments of the screen.

    All I can do is hold down the power button and shut down and then restart.

    Downloaded and installed the OS X El Capitan, ran the Apple Hardware test, evrything OK.

    Any other ideas where to troubleshoot them?

  • Mac Pro 2013 randomly restart problem

    Hello

    Here's my problem: I have a Mac Pro end of 2013 (6 cores, 16 GB ram, over-pants D500, running OS X 10.10.5 with a WACOM Cintiq 21 - UX as my view only) who has, for the last month or so been randomly restart itself.

    There are some days where it might be three or four times and then days where it won't do it at all. Also there are moments where it works well for hours, but then if I turned off the Mac Pro, it will crash and restart. Sometimes it will freeze momentarily application-wise (but the cursor moves but does nothing) before it restarts but usually just the screen goes black and then it restarts without any warning. I still get the black screen with the «your computer has restarted...» Press any key' and of course, it generates a crash report that I submit to Apple every time (that I'll post more recent one below as well.) I did start secure upward, reset the PRAM, booted single-user, just that I found online to do which is recommended. But nothing seems to have done something to help.

    The Cintiq is connected through a DVI adapter to Thunderbolt. I also have Mercury Elite Dual Pro Rack hung RAID normally via Thunderbolt. There are times when I think that there is a problem with the RAID box and the Mac Pro but not sure. As there is a problem with the Thundebolt ports. I tried to pass the cables autour, but it has not seemed to have made all the difference. This also has all seems to have coincided with the last update of OS X where I've also updated the driver for WACOM Cintiq (I since past to the old driver). Is this all just a matter of software conflict?

    I found an Apple Support thread where someone has indicated that a Kernel Panic may cause this, but then it also seems similar to what I've found, that was the issue with the Macbook Pro, which had problems with graphics a bit backward.

    In any case, here's a crash report if it helps and thank you for any help that anyone can send my way!

    Mac Pro graphics problems (end 2013)

    Mac pro end of 2013 freezes with the spinning wheel

  • Why has my laptop started to randomly stop before turning off

    Original title: computer power questions

    Why has my laptop started to randomly stop before turning off? I had no problem with this computer at all for more than a year. I tried to run all the updates available, but of course, it turned off before she finished. Sometimes it will run fine then others that it is a nightmare. can anyone help please? I would be very happy to help!

    Hello

    Could be heat related - try using a small fan to blow into the air intakes to see if that helps.
    It is just like it loses power or stop it in the normal way?

    Remove ALL power and reinstall all the memory cards and cables (both ends where possible).
    in fact, remove and replace - don't do not just tight. Remove the dust bunnies and clean the
    air vents. Check that fans are working (before and after opening the case). When your laptop on all the
    You can do is to reinstall the memory and clean the vents (still may try to add a small fan as a
    test).

    This sounds like material so if the above does not help you then probably need the help of a
    real computer store (not of leeks and glances at a Best Buy or other department stores) or the system
    Support from the manufacturer.

    ===========================================================

    Check with these utilities to see if information may be collected: BlueScreenView run to see if
    There were some BlueScreens and MyEventViewer at the time, check if the stop (or a little
    seconds before) see the event log contains useful information.

    It is an excellent tool for displaying the blue screen error information

    -Free - BlueScreenView scans all your minidump files created during "blue screen of death," collisions
    and displays information about all accidents of a table.
    http://www.NirSoft.NET/utils/blue_screen_view.html

    -------------

    MyEventViewer can be verified at the time of the blue screen (BSOD) within a second or so of the
    time of the BSOD to provide more information about the possible cause - see TIP.

    MyEventViewer - free - a simple alternative in the standard Windows Event Viewer.
    TIP - Options - Advanced filter allows you to see a period of time instead of the whole of the record-
    Set it for a bit before and after the time of the BSOD.
    http://www.NirSoft.NET/utils/my_event_viewer.html

    ------------

    AppCrashView - free - a small utility for Windows Vista and Windows 7 that displays the details of all the
    application goes down has occurred in your system. The information breaks down is extracted from the .wer
    the files created by the Windows Error Reporting (WER) of the operating system component of each
    time that an accident has occurred. AppCrashView also allows you to easily record the list of accidents to
    text/html/csv/xml file.
    http://www.NirSoft.NET/utils/app_crash_view.html

    ------------------------------

    Also do this so you can see the probable bluescreens. (You may or may not be able to see
    them if they occur even after doing this according to the cause.)

    Windows Vista restarts automatically if your computer encounters an error that requires him to plant.
    http://www.winvistatips.com/disable-automatic-restart-T84.html

    =========================================

    What antivirus/antispyware/security products do you have on the machine? Be one you have NEVER
    on this machine, including those you have uninstalled (they leave leftovers behind which can cause
    strange problems).

    =========================================
    =========================================

    More if needed and you think that the closure could related to the Options of food or sleep.

    Check your settings (BIOS/CMOS) - usually F2 as you start - Wake on Lan, Wake on Modem and so on.

  • MacBook Pro (15 inch, end 2013) with MacOS Sierra 10.12: kernel_task maxing out CPU with external display

    I have a maxed out end 2013 the MacBook Pro Core i7 to 2.6 GHz, 16 GB of DDR3 RAM, 1 TB SSD, NVIDIA GeForce GT 750 M 2048 MB, Intel Iris Pro 1536 MB.

    Also, I have a DELL P2415Q Display 24 inches (3840 x 2160) using Thunderbolt, are involved through the headphone jack and use a USB for lightning to recharge my iPhone.

    I upgraded to macOS Sierra the day he is released and had no problems until this morning. I unplugged my external screen and speakers and used my laptop for about 15 minutes, the battery, and then returned to my office and plugged my Thunderbolt, rear speakers display in and my CPU shot at 100% and never came back down. My Mac is essentially useless because kernel_task is eating all my CPU and to prevent another asks to enter the CPU.

    I have since audited equipment - everything was fine, reset the NVRAM and I tried to erase IOPlatformPluginFamily.kext .plist files but I couldn't on my Mac (trying to follow this guide, started in Safe Mode and everything then went to try and find the file and my Mac just does not have it). When my external screen is plugged if I'm doing anything CPU intensive (videophone, opening of Chrome, etc.) then my kernel_task gets mad again, and the only way to move is to unplug my screen. Connect my iPhone to charge the tips also my kernel_task as well. I followed my internal temperatures, and nothing was out of the ordinary, to cold currently at about 140 °.

    At this point, it seems that any time that puts something on the charging system and increase the temperature internal internal components of my Mac kernel_task maxes my CPU, which brings my Mac to its knees.

    Any ideas how to fix? Is this just a major bug in 10.12?

    Hi, Trent L.

    Try this - problems with macOS Sierra? This fix can help you.

    He got rid of all my macOS strangeness of the Sierra.

    GeekBench is a crude tool that is useful for computers compare configured identically. Means "Identically configured" quite the same hardware running identically configured systems with identical changes, as appropriate.

    As says Geekbench works best when it is the only application running. Comparing the performance of your Mac to others requires the abandonment of all other open applications in addition to process who can have no user interface.

    To identify the processes that are running on your Mac in order to see how they affect the activity and performance of your Mac, use the activity monitor: use the activity monitor to your Mac - Apple Support.

  • My mac pro end 2013 connecto to 3rd monitor used

    I just got a couple of monitors Samsung 4 K and I connected to my Mac Pro model 2013 end that has two graphics cards AMD over-pants D700. I also want to plug a 4 K TV to my installation in order to show the greatest screen previews for customers. I've separated the connections of each monitor in the ports of different buses, as shown in the Apple Web site. Both screens are connected via thunderbolt and the TV is connected via HDMI. The problem is when I plug the TV one of the monitors completely loses the signal. I tried to swap the connections of ports between the two monitors and the TV but the result is the same, the computer will only send the signals of two of the three connected. I would be grateful someone knows how to fix this problem, thanks.

    You said: "the two screens are connected via thunderbolt and the TV is connected via HDMI.".

    You say you have two screens Thunderbolt?

    If this isn't the case, which is entered on the monitors?

    If this isn't the case, entered ui displayport/mini displayport may be both legacy connections (DVI or HDMI). For more than two, you need an adopter active.

    Each device is connected to another bus Thunderbolt?

  • What happens with the Mac Pro (end 2013)?

    Hello!

    I'm Marc Urtasun, Spain. I have a Pro Mac (end 2013) with 3, 5 GHz 6-Core and two AMD over-pants D500. I am an artist and a 3d animator and I always work with 3d, made, video... and I need a more powerful computer now, because on the 3d, Mac users are moving to Windows due to the advantage of the GPU with CUDA...

    I would like to ask two things:

    -are planning an update or something for Apple's Mac Pro?

    -Can I update my Mac Pro 12 hearts? or update with a graphics card more powerful?

    Thank you

    -All those here who know the future plans Apple could not reveal that, because of the NDA, they signed.

    -Yes, you upgrade to the D700, but that requires to replace two wide boards that contain the GPU and other components. You will find the D700, as Apple does not sell to them.

  • iMac G5 end 2005

    Hi, I have also an iMac G5, end of 2005, and although it works very well for an older iMac, I've got troubles get Skype running, it simply didn't and also none of the two versions of OpenOffice 2.1 (too much), or any version of Microsoft found for this machine which I really like and I intend to sell if I can not both running

    I searched the internet for at least Skype running without success.

    Any help in these matters on your part? I had planned to keep it at home, another iMac for work, but the problem on the G5 processor...

    I hope to get help

    The most appreciated.

    software development is long over. 11 years in computers is like saying you have Philco TV from 1952 and want to know how to connect a HDMI adapter to allow the display of 4K.

    If you are planning keep this use of the machine the software developed for this and any system that requires a backend support like Skype; do not expect to work if MS makes changes to this software support systems.

  • Acer S277HK 4K - retina of Macbook Pro 13 "(model end 2013)

    Hi Forum - I recently bought an Acer S277HK 4 K/60 Hz monitor and use as an external monitor with my Macbook Pro retina 13 "(modèle de fin 2013)."  I am connected using the "Cable issues Mini DisplayPort / Mini Displayport 4 K ready cable" to connect macbook to monitor.  So far, I cannot get the resolution of Acer to reach 4K / 60 Hz.   I did a lot of research on various forums and sites as possible and so far, everything I've seen leads me to believe that my MBP 13 '' end 2013 retina should support a 4K connection / 60 Hz, but so far, am not able to achieve this.  Someone has advice on how I can solve reach higher in the Acer external monitor resolution?  I've seen a few comments need to use 'switchrex' to adjust the settings, but no indication on this is extremely appreciated!  Thank you.

    You should be able to get 4K@60 Hz with cable 1.2 DP/CDM? You have a cable 1.2?

    A 4K cable does not mean it is 1.2 DP.

    The monitor configuration screens has an option to support 1.2 DP? Some do it.
