If you have time to try this I would be very interested to know if it works to resolve the issue. Thanks!
So, I tried it out.
I had to use my MacBook Pro because I was missing a special cable to connect the output HDMI of my switch to the NUC.

So the setup was the following:
My MacBook was connected over the HDMI port to the switch. The output of the switch was the TV. The switch had only the MyBook as output, the other HDMI output of the switch was not connected.
Over display port to HDMI I connected the MacBook separate to my monitor.
When I turned the TV off, the mentioned mouse problems occurred. But it has not effect to switch the switch.
This can be a problem of my specific switch, because when the switch occurred there were no short black screen when the OS rearrange the desktop.

So I will stay with my unplugging of the HDMI cable. To prevent damage on the NUC HDMI port you could use a short HDMI extension cable.

Thank you muchly for testing this. Y, I agree that if there was no temporary black screen then from the computer's standpoint the source was never disconnected -- perhaps your switch maintains any connected HDMI as active, which would ordinarily be a good thing. If I happen to buy a pure HDMI switch on Amazon I will test it, but you're right that with a short extension cord (or even just the necessary mini HDMI to HDMI adapter on the NUC) you can prevent the wear/tear on the backplate port.

Finally got my NUCi5RYH operating reliably. System details:
Intel NUCi5RYH
2x 8GB Crucial SODIMM
Samsung EVO 850 250GB SSD
500GB SATA hard drive
Philips monitor 1920x1080
HDMI audio via the monitor, haven't tried the headphone jack
OSX 10.11.2

First I want to thank ammulder and all others who worked out all the guide details. The software installation went smoothly as per the guide. The only software trouble was the rebooting issues associated with BIOS 350. I changed it to 348 and that fixed that problem.

But I did have intermittent hardware problems. The screen would go blank for anything from a second to half an hour whenever I turned something else in the room on or off. This was due to a poor display port to HDMI cable. Changed to a mini-HDMI to HDMI cable and problem 2 fixed.

Next were intermittent problems such as the screen blanking and rebooting. I suspected a memory problem. Tried a memory test program but passed. Then decided to open the case and reseat RAM. These seemed ok. Then went to reseat the SSD and found the PCB was deformed. The cables to the SATA drive had been caught between the SSD and the pad under the SATA mount, and were pressing down on the SSD board. I put the SSD back in and kept the cables out of the way as the case went back together.
It has been a week since and the NUC has run everyday without these problems occuring again.

Thanks everyone.

I'm still having random reboots up to 10 times per day on my NUC5i5-RYH, 16GB / 512GBm.2 machine. There is no warning or typical behavior that causes them; they happen when the machine is just sitting idle or when I'm using it.

One question I have:
What does everyone's screens look like on boot?
For me, the apple logo is screwed up during the last 1/3 of the loading bar (i know this is normal),
but then, one screen (hdmi) is tri-color static noise, the other screen is distorted. Then, the hdmi screen goes black, the other screen goes normal, but just one monitor desktop, then, the HDMI screen kicks on and it switches to dual monitor desktop.

Is this typical of everyone else's boot? Is it an indicator of why my NUC is rebooting randomly?

I'm using two displays on displayport and HDMI, and after the Apple logo gores screwy during the last 1/2 of boot, both screens display the desktop (login screen) normally.

Try using just the DP monitor with nothing on HDMI and seeing if you still get reboots; try just the HDMI and not the displayport; try using a single stick of RAM (which has to be in the bottom slot, I believe) and then the other stick; try other RAM if available; try installing and booting from external disk only -- and see if you still get reboots, to try an narrow down the problem.

One last issue solved on my NUC, not with OSX but with the NUC hardware -- something about the shape of the NUC case makes it really hard for my Microsoft wireless keyboard usb transmitter to stay in contact with my wireless keyboard, regardless of whether the usb dongle is in the front or back USB ports. I found that putting it on a short extension cord, even a few inches, fixes this.

To make it look a little cleaner, I used a passthrough USB volt/amp meter I have to give it just a few inches of clearance from the NUC case, which fixed the connection issues. Interestingly, it barely tips the scales at 0.01 amps, barely at the threshold of any reading at all. Picture attached. You can see my NUC in the foreground, and my 7-port USB hub/ext hdds/dead 2011 Mac Mini in the bg.

I had a similar problem. From my reading it was an interference in the 2.4 GHz range caused by USB 3 peripherals being plugged in too close to the wireless mouse. My workaround was to make sure the wireless keyboard/mouse was not plugged in on the same side as any USB3 devices. This helped, but it wasn't perfect.

I just got some wires to hook up my internal USB2 headers. I'm planning to put the wireless keyboard and internet dongles in there, so hopefully that will completely get rid of the issue.

Thank you for letting me know that you see this too and that it's a known issue! I found the support doc you were talking about, and yes you are correct -- they specifically reference USB 3.0 being a potential source of interference for 2.4ghz wireless devices, and they recommend using an extension cable as a solution, as we both basically thought of. Pls let me know if the internal header solves the issue, I would be very interested to know. Thanks!

'...the noise from USB 3.0 data spectrum can be high(in the 2.4–2.5 GHz range). This noise can radiate from the USB 3.0 connector on aPC platform, the USB 3.0 connector on the peripheral device or the USB 3.0 cable. Ifthe antenna of a wireless device operating in this band is placed close to any of theabove USB 3.0 radiation channels, it can pick up the broadband noise. The broadbandnoise emitted from a USB 3.0 device can affect the SNR and limit the sensitivity of anywireless receiver whose antenna is physically located close to the USB 3.0 device. This may result in a drop in throughput on the wireless link.'

Try this for BIOS 352 (may work for 350 too):

On the Advanced / Power screen, check USB S4/S5 Power, but make sure the following are all off/unchecked:
Wake on LAN from S4/S5
Wake System from S5
Wake on USB from S5
PCIe ASPM Support
Native ACPI OS PCIe Support

That makes my NUC5i5RYK shut down without starting up again. I am still able to sleep and wake it again by e.g. clicking the mouse.

This solved the restart issue after shutdown on BIOS 0352.

Thanks for the great work and this excellent guide, everything is working on my NUC5i3RYH including bluetooth, I was able to pair my magic mouse, apple wireless keyboard (reset it if you had it paired before hand with another computer, otherwise it won't pair, also, you must pair it trough the keyboard preference pane instead of the bluetooth preference pane).

Thank you for your reply, and sorry about the delayed response. Here is a photo of the panic: http://i.imgur.com/AO5viLs.jpg

(Sorry about the flash. If it's obstructive let me know.)

I'm having same exact issue here. Running NUC5i5MYHE running BIOS version 0026. Any help here would be greatly appreciated.

Seem like the issue itself is with ACPI.

Apple16X50ACPIO: Identified Serial Port on ACPI Device=UAR1
Apple16X50UARTSync0: Detected 16550AF/C/CF FIFO=16 MaxBaud=115200
<CUT>
IOBluetoothHostControlerUARTransport::ConfigurePM ACPI device not found
panic(put 0 caller …

when I put -x flag I can boot to the installer but then after reboot I get stuck again.




UPDATE:
Seems like after unchecking "Serial Port" under DEVICES -> ONBOARD DEVICES tab -> in the right side panel - "Legacy Devices Configuraiton"

I don't get the kernel panic anymore. Can get into installer w/o issues. Hopefully I can follow the guide from that point on.
