Q: Retina iMac Freezing and Restarting

Hi,

 

So I bought the 5k Retina iMac the other day, on November 5th. When I brought it home it was constantly freezing and restarting. There's no signs of panic in the diagnostics, apple couldn't figure it out over the phone when they had me resetting it. It happened during simple things, making a music playlist on spotify or when I had photoshop or autodesk maya opened. Nothing popped up when it froze in any signs of error it simply just froze and then restarted the computer by itself. After this happened about 8 times I brought it back yesterday and the apple genius said it was probably hardware issues and then promptly gave me another computer.

 

Now I'm home with a new retina iMac and now the same problem is happening. It's frozen and restarted 3 times when I'm doing simple things. I don't even have much installed on this computer yet, I haven't really transferred over my files. I have Skype, photoshop, illustrator, maya, spotify, etc on here so I don't understand what is causing these issues. Is there just a problem with this iMac that no one has reported yet? Has anyone else bought the 5k iMac sharing the same problems? I'm at a loss of what to do here if I should just return for a full refund at this point and deal with my ever dying 2011 iMac. It's frustrating getting a new computer and it not working and it's kind of disheartening. All the specs of the computer are the standard purchase from the website I just don't know what to do. Any advice? Thank you.

iMac with Retina 5K display, iOS 8.1

    Hello!

    I also have terrible freeze. At first, it stops during the first start, and now it has problem with different apps. Sometimes it disable sound, and i have to relaunch sound apps. Today, it was a problem to log out and shutdown... %(

     

    iMac Retina 3tb FD, 8 Gb RAM.

     

    Maybe i should test some hardwares? Any ideas? Or just wait for 10.10.2?

     

    Do you have any success, except disabling FD?

    iMac 5 K will not complete start up.  Received with 16 GB Ram, added 16 GB of third party Ram.  Started up and Ram showed up in about Mac.  Mouse froze up many times.  Removed third party ram.  Now it will not complete start up, no chimes and turns itself off after 5 minutes.

     

    Please help

    Apple replaced machine.  You are best off doing the same.

    So, finally 10.10.2 is here... and it become stable, but graphic is very very slow... even changing desktop images is "step by step"

    And what about you? Do you have same problems?

    Hi!

     

    Just want to inform that I have same problem, my new Retina iMac restarts sometimes without any warning. It doesn't seem to be OS related, because I use Windows 8.1.

    same issue, although the problem seems much worse for me when working in adobe premiere, as it freezes up almost every 5 minutes when i scrub in the timeline. The problem may be Ram related. i have someone coming in from the reseller store to replace the ram in my system. these kind of issues are really horrible and should never be allowed to get past the test phase of these very expensive machines. One would not even accept it from a mix and match windows setup, let alone hardware that is supposed to work well together. extremely disappointing.

    I had exactly the same problem but it was diagnosed that my poorly crafted (probably software related) external LaCie 6GB was the source of the forced restart problem. Of course I now have to transfer everything back to my old Mac (which will take a day or so) then transfer everything back to new Mac via Mac-to-Mac connection. To say i am annoyed at purchasing a $600cdn external drive only to have it make my computer bug out is an understatement.

    Similar problem on 27 inch retina iMac; unable to shutdown completely or to start up. The problem is erratic. Sometimes there is no start up chime; other times I get sign in screen but after signing in the screen goes black and nothing more happens. Many troubleshooting tests run without success. Apple to their credit has suggested likely hardware problem and replaced it twice. But still the problem occurs. Have found that the problem stops if I disconnect some or all USB and Thunderbolt connections from the back of the computer. Nevertheless, there is no single (or multiple) device that consistently offends.

    Just chiming in with my similar woes. Purchased my new iMac (Retina 5K, 27-inch, Late 2015, 4 GHz Intel Core i7) in February and noticed immediately that it was sluggish and glitchy compared to my older late 2012 27-inch iMac:

     

    1. Random and erratic behaviour from the start
    2. Spinning Beach Ball Of Doom doing the most menial tasks
    3. Bluetooth keyboard disconnects for seconds at a time, numerous times an hour - so frustrating writing emails
    4. All progs & system eventually grind to a halt
    5. Audio randomly glitchy and then grinds to a static-y halt - half the time I thought it was the music I was listening to
    6. Screen refresh very buggy on occasions - major pixilation, artefacts, weird sections of the screen flickering
    7. Black screen at startup - I'd be waiting for it to display and realise that the computer is somehow on, with no chime, but the display is black - no way to get in other than force reboot
    8. Error messages regarding iTunes Store nearly always
    9. Mail giving me disconnected accounts messages, randomly offline
    10. Unable to have many Tabs open in Chrome, etc, etc, etc

     

    To name just a few. I brought it back to the store after 3-4 weeks and they graciously gave me a new computer.

     

    Most of the problems still exist but do seem a little infrequent.

     

    The iTunes error messages have stopped, though I occasionally get iCloud error messages. My computer just randomly rebooted straight into the User Login Screen (like, the screen just went blank for a second and I thought it was a powercut, but a second later I was presented with the unfamiliar User login Screen - normally it just boots straight into my account) just a few minutes ago (hence this search for similar stories) and it is beginning to seriously **** me off that my old machine (which my wife now claims) is so much more stable and 'usable' than this state-of-the-art glitch-fest.

     

    Have moved from Sydney to the country so no way can I just 'drop-in' and get it checked. There is obviously some flaw in the design of these retina macs and simply replacing them doesn't solve the issue. There is no way I would recommend the retina iMacs to anyone who needs to get work done on their computer. Too much work has been lost and time wasted trying to 'fix' things.

     

    My old mac looks like a dream machine but my missus is guarding it like it's our baby!

     

    Anyway, just my 2 cents. I needed to rant after that horror reboot.

    I'm having the same problem in my iMac Retina 5k, 27-inch, late 2015. The operating system is EL CAPITAN . Someone figured out what is causing the problem?
