Q: Unexpected Reboots

I have a iMac Retina 5k, 27 inch, Late 2015 that has been working just great until I installed OS X 10.11.4.

 

Since then I get unexpected reboots; from the log the unexpected reboots are "Previous shutdown cause: -128"

 

This is a 3 day log.

 

Apr  1 20:23:20 iMac kernel[0]: Previous shutdown cause: 3

Apr  2 10:25:24 localhost kernel[0]: Previous shutdown cause: 5

Apr  2 11:37:13 wrf-iMac kernel[0]: Previous shutdown cause: 5

Apr  3 09:30:34 localhost kernel[0]: Previous shutdown cause: 5

Apr  3 13:08:27 wrf-iMac kernel[0]: Previous shutdown cause: -128

Apr  3 15:28:37 wrf-iMac kernel[0]: Previous shutdown cause: -128

Apr  3 17:27:23 wrf-iMac kernel[0]: Previous shutdown cause: -128

Apr  3 17:31:35 wrf-iMac kernel[0]: Previous shutdown cause: -128

Apr  3 20:55:33 wrf-iMac kernel[0]: Previous shutdown cause: 5

Apr  3 21:03:28 wrf-iMac kernel[0]: Previous shutdown cause: 5

Apr  3 21:34:24 localhost kernel[0]: Previous shutdown cause: 5

 

There are no externals plugged into the ports and I am using the Magic wireless Keyboard and Magic 2 wireless Mouse.

 

I have already taken it to local Apple Store and left it for 5 days for them to find the cause; they said they could find nothing wrong with it.

 

And yes I have reinstalled OS X 10.11.4, after wiping the drive, 4 times. I have also reset the PRAM and SMC.

 

Anyone have an ideas.

    Ive got the same problem, bought iMac in Feb, ever since update it started the random rebooting and developed a problem with the bluetooth. When it is first switched on the bluetooth is disabled, the only way to solve it is to restart the iMac via keyboard shortcut. (i use a wired keyboard).

    Trouble is I'm over the 14day return period so could you please advise me on who to contact in regards to getting this solved , its draining me.

     

    Thanks in advance.

     

    Kind Regards

    Same issue (as logged here: Retina iMac Freezing and Restarting and here: Re: iMac (Retina 5K, 27-inch, Late 2015) Randomly Restarts Without Errors) but I forgot to add to the list the number of Kernal Panics I have seen since I purchased the Retina iMac.

     

    Too many. Way too many. They used to be such an ubiquitous feature of OSX in the early years but I cannot remember the last time I saw my screen go grey with the Kernal Panic message prior to this iMac. Since I got it there have been over a dozen I would reckon.

     

    A dozen heart-stopping moments of sheer Panic as I realise that my work is lost.

     

    Thanks to Mike Sombrio's info in the first replay I found the most recent Kernal Panic log:

    I wish I understood any of the above.

     

    My suspicions definitely lie with an some issue with the Retina graphics card. The screen refresh can be seriously buggy at times. Being honest, and this is a just my observation, adding 2x16GB RAM modules to the 2x4GB ones the iMac came with has had virtually no noticeable effect to the performance of the mac. It struggles with a load of chrome tabs open, plus some Creative Suite apps, Parallels 11 and a Windows10 environment just as much as with the original 8GB (and my late 2012 27 iMac with 32GB RAM was able to perform so smoothly with the exact same requirements). It almost seems like the system RAM requirements are being dumped into the Graphics Card, hence the glitches, stutters, screen redraw artefacts, freezes and crashes. I know that is probably technically impossible but it sure seems like how it's behaving.

     

    I wish there was some way of consolidating all the different threads that are highlighting the same thing - the fact that there is a serious flaw in these Late 2015 retina iMacs. There are so many now.

    Just noticed in that panic report that the backtrace references "com.apple.AMDRadeonX4000" but the actual graphics card is AMD Radeon R9 M390.

     

    I have no idea if that is relevant. But it does look like a discrepancy.

    It looks like your graphics card is failing but there are a few things you need to eliminate before you make an appointment for service. Apple is going to insist on these anyway so we'd might as well get them out of the way. First you need to uninstall Sophos, the panic started when your iMac saw Sophos and it's been known to cause problems anyway so uninstall it. Next remove the third party ram. If the panics persist see if you can post another panic log. If the panics stop then you can try adding the ram back in and testing.

    Hi Mike,

     

    Many thanks for your response. I dunno how you understand these logs. Are there any walk-throughs or "idiot guides" to these logs and what they mean?

     

    These random reboots and kernal panics all happened before I purchased the 3rd party RAM and I had hoped that the issue was the default 8GB was too little for the basic tools of a graphic designer on a mac - Photoshop, Illustrator, Chrome, Suitcase, Office, iTunes and Mail... y'know, the basics!

     

    Here is today's panic log, if you can discern a pattern. I was messing around within Ableton Live (quite a few crashes happen within Ableton which makes me think the audio card and graphics cards or something between them is banjaxed) when this happened:

    Apologies for the data dump and the brain drain. It's just great (and heartbreaking) to see others experiencing the same issues with this particular model. I would love to know how many Late 2015 27" iMacs have been returned/replaced as compared to other models over the same space of time.
