The macOS 10.12 guests Window Server crashes from time to time

[IOOI]

I am experiencing the following: Right after logging in into my macOS 10.12 guest the Window Server of the guest crashes bouncing me back to the login screen. Host is an OS X 10.10.5, VirtualBox is 5.1.8 r111374 (Qt5.5.1). Often I have to log in five to ten times until the session seems to be "stable". Even then the Window Server crashes from time to time. Anyone experiencing the same?

Host: OSX 10.9.5
VirtualBox: 5.1.9 r111957 (Qt5.6.2)

I can't say that I've seen the 10.12 window server crashing. I left it overnight to test after I saw your message, with a couple of users logged in and a couple of apps running per user. Nothing.

I do remember seeing the login / crash / return to login sequence before with OSX clients. I don't remember when, I don't remember which version of VirtualBox or OSX host/guest. I haven't seen it in a long, long time...

Anything out of the "ordinary" running on the host or guest that you think might be interfering/causing this?

[socratis]

Nothing that I am aware of. Especially in the guest I have nothing running for now since it is not reliable for me. A difference between your and my setup I noticed is that you're running 10.9 as host, while in my case it is 10.10. If I find the time I'll try to set up a fresh 10.10 host on some external drive and watch if the window server keeps on crashing

I installed macOS Sierra 10.12 like Guest on VirtualBox 5.1.10 on my MacBook Air with macOS Sierra too.

I facing errors! I login with difficulties an when I can, raise the error and I need to log in... the machine is not halt totally.

For me is difficult to extract all Logs.

For me is difficult to extract all Logs.

Not at all. Just follow these steps:

1. Start the VM. Not from a saved or paused state. Clean start.
2. Take the steps required to generate/observe the error.
3. Shut down the VM (if it hasn't aborted by itself). Not saved, not paused. Completely shut down. If you can't shut it down by normal means, close the VM window and select "Power off".
4. Right-click on the VM in the VirtualBox Manager. Select "Show Log..."
5. Save it (just the first log), ZIP it and attach it in your response (see the "Upload attachment" tab below the reply form).

Although I do not think that you have the same error as the original poster...

Hi, Here the link for Video https://youtu.be/xALbh0S9FwQ

Finding the Word WindowServer, not was found! Where I can find it?

[socratis]

• The video was helpful, you do have the same problem as the original poster.
• I need to know the exact details of how you installed the guest, mainly how you created the ISO or the DMG file that you used to install it.
• Please attach the VBox.log file locally (see picture below). Zip them first. Not a lot of people will go to 3rd party sites.

To create iso file:

Code: Select all   Expand viewCollapse view

$ hdiutil attach /Users/josebernal/Downloads/InstallESD.dmg -nobrowse -noverify -mountpoint /Volumes/esd
$ hdiutil create -o /Users/josebernal/Downloads/macOSInstaller.cdr -size 7.5g -layout SPUD -fs HFS+J
$ hdiutil attach /Users/josebernal/Downloads/macOSInstaller.cdr.dmg  -nobrowse -noverify -mountpoint /Volumes/iso
$ asr restore -source /Volumes/esd/BaseSystem.dmg -target /Volumes/iso -noprompt -noverify -erase
$ sudo rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages
$ cp -rp /Volumes/esd/Packages /Volumes/OS\ X\ Base\ System/System/Installation
$ cp -rp /Volumes/esd/BaseSystem.chunklist /Volumes/OS\ X\ Base\ System/
$ cp -rp /Volumes/esd/BaseSystem.dmg /Volumes/OS\ X\ Base\ System/
$ hdiutil detach /Volumes/esd
$ hdiutil detach /Volumes/OS\ X\ Base\ System
$ hdiutil convert /Users/josebernal/Downloads/macOSInstaller.cdr.dmg -format UDTO -o /Users/josebernal/Downloads/macOSInstaller.iso
$ mv /Users/josebernal/Downloads/macOSInstaller.iso.cdr /Users/josebernal/Downloads/macOSSierraInstaller.iso


I noted this two operations:

Code: Select all   Expand viewCollapse view

$ hdiutil convert /Users/josebernal/Downloads/macOSInstaller.cdr.dmg -format UDTO -o /Users/josebernal/Downloads/macOSInstaller.iso
$ mv /Users/josebernal/Downloads/macOSInstaller.iso.cdr /Users/josebernal/Downloads/macOSSierraInstaller.iso

are equivalent to:

Code: Select all   Expand viewCollapse view

$ mv /Users/josebernal/Downloads/macOSInstaller.cdr.dmg /Users/josebernal/Downloads/macOSInstaller.iso

Because the result tell me this:

Code: Select all   Expand viewCollapse view

$ cmp /Users/josebernal/Downloads/macOSInstaller.iso /Users/josebernal/Downloads/macOSSierraInstaller.iso
$

No difference found!!!

I do not know if it influences the failure
I take like base Mac OS X 10.11 El Capitan (64-bit), 2 Processors, Video Memory 128, etc... (https://support.apple.com/kb/SP742?loca ... cale=en_US)
Audio Controller with Intel HD Audio or ICH AC97
USB Controller with OHCI, EHCI or xHCI.

Testing with the same conditions, but taking Mac OS X (64-bit), I haven't the error messages....

Hi, Please what flavor Version You take like base?

[socratis]

VirtualBox VM 5.1.10 r112026 darwin.amd64 (Nov 21 2016 17:53:09) release log

Please upgrade to the latest 5.1.14 (as of this writing).

00:00:01.971722 [/Devices/ichac97/] (level 2)

You have set your audio to "ICH AC97". Please use the default "Intel HD Audio".

00:00:01.971450   NumCPUs           <integer> = 0x0000000000000002 (2)

00:00:02.282533 CPUM: Physical host cores: 2

You have assigned all your CPUs to the VM. The host is going to run low on resources, since VirtualBox cares about physical processors, not logical ones. See: CPU Cores versus threads.

• A Core is a hardware term that describes the number of independent central processing units in a single computing component (die or chip).
• A Thread, or thread of execution (or logical CPU), is a software term for the basic ordered sequence of instructions that can be passed through or processed by a single CPU core.

Finally, I'd like you to explain the following:

Testing with the same conditions, but taking Mac OS X (64-bit), I haven't the error messages....

Does that mean that if you change the VM Settings » General » Basic » Version, to "Mac OS X (64-bit)" you can login fine and you don't see the OSX window manager crash?

[joseluisbz]

Socratis!

I installed 9 times taking like base Mac OS X El Capitan 64 bits with the same result (messages error), but using General Mac OS X 64bits two times no presenting this error messages! I think that was Solved!

I tested Audio ICH AC97 and Intel HD Audio, Only works Intel HD Audio.

I have 4 Processors, checking with

Code: Select all   Expand viewCollapse view

sysctl -n hw.ncpu

, and Assigned majority times 2 processors, maybe some times I selected erroneously more than 2.


Socratis, is it possible to check changes (or differences) between Mac OS X El Capitan 64 bits and General Mac OS X 64bits?

[socratis]

I have 4 Processors, checking with "sysctl -n hw.ncpu"

No, you do not have 4 physical processors, you have 2. And as I told you, do not assign more than 1 CPU to the VM.
Here's your processor's information from Intel: https://ark.intel.com/products/84984/In ... o-2_70-GHz.
And look at the System Information » Hardware » Total number of cores.
And if you want to use "sysctl", then look at the proper parameter:

Code: Select all   Expand viewCollapse view

sysctl hw.physicalcpu
sysctl hw.logicalcpu


Socratis, is it possible to check changes (or differences) between Mac OS X El Capitan 64 bits and General Mac OS X 64bits?

It can be done, but how is that going to help you? You've already found a workaround. The differences are really esoteric and that's why they're not exposed.
