I ran into an error after installing VMware Fusion on my mac, that it couldn't find /dev/vmmon. After some digging, I've learned that there are only so many available character devices, and that other software I have has consumed them.
Since I actively use Viscosity and Virtualbox (for the time being), the only other one that I could find I had was Intel HAXM driver.
Instructions online suggest to run a script to uninstall it, however that script did not exist on my laptop.
I unloaded the driver with the command:
sudo kextunload -b com.intel.kext.intelhaxm
I wanted to determine if there is anything else I need to do, will this driver attempt to reload during boot?
Thanks!
The Intel HAXM docs show that as of 2018, there is an uninstall script:
sudo /Library/Extensions/intelhaxm.kext/Contents/Resources/uninstall.sh
I had the same issue, Tim Potter's solution fixed my issue ,
sudo kextunload -b com.intel.kext.intelhaxm
Thanks
Cannot find /dev/vmmon (VMware Fusion 8.5.1 on macOS 10.12.1)
I had the same problem.
After a lot of trial and error, and helpful support from VMware I got it to work by
Create another user on the mac
log in as that new user
start fusion
create a new virtual machine (custom, windows7, no actual OS installation)
If machine starts, then vmmon is restored correctly
switch back to your normal user, start fusion and your existing vm
I have not investigated WHY this works, and VMware-support couldn´t tell me either. For now - I do not care. It works, and I can run my vms again.

I have installed Virtualbox developer preview on my Mac M1 and am trying to run Hortonworks Sandbox on it. However, the application keeps closing when I click 'Start' and I cannot find any information on my that is happening. The error message that showed up was 'You must specify a machine to start, using the command line.' When I looked up this error, everyone says to use an older version of Virtualbox but there is no older version that is compatible with Mac M1. Can someone tell me how I can fix this problem and run sandbox on my system?
Hortonworks doesn't exist as a company anymore, and the sandbox hasn't been updated since before M1 Macs were even available, so unless you want to run x86 VM in VirtualBox (or Docker image with Qemu), no, it's not possible.
Latest Hadoop 3 already supports ARM processors, and you can use Homebrew to install it. The Sandbox uses old Hadoop 2.7.3, last I checked.
I just bought the new Dell XPS 13 Developer edition which came preinstalled with ubuntu 14.04.
After the initial boot it seemed a bit slow, but then it updated and worked fine, then later the same day seemed to slow down again.
Even running programs like eclipse it seems very laggy on, which is odd. As the specifications should be fine;
16gb Ram
i7-6560U cpu
64-bit
500gb ssd.
I'm not sure what to post to help, so any suggestions would be great.
Thank you!
Check what is using much system load using the command top.
You can also use htop which is easier to read.
For that install it using the following command:
sudo apt-get install htop
Have you tried reinstalling Ubuntu 14.04.3 LTS on your computer?
In future, please use the Ask Ubuntu forums for such questions.
I had a similar issue in my lenovo thinkpad with i7 and 16GB. pycharm and android studio was exteremely slow and it was almost not usable for any development. Even it took a while for the terminal to start.
Finally I found a solution for my issue. I needed to disable "speed step" feature in BIOS.

I'm having some problems with my graphics cards driver and I hoped you guys could help me out. I mispurposeadly changed the x.org's driver to a propietary one and ended with my computer falling apart with the login loop problem, typical of Thrusty Thar. However, I managed via console to purge the fglrx driver using sudo apt-get purge and managed to access the desktop graphically. After that none of the usb ports or sd slot worked, nor did the graphics card, only the ethernet port, so I upgraded Ubuntu Thrusty Thar to Utopical Unicornwith the hope it would fix the driver's problem. It didn't. Can you help me find a solution to my problem?
In the worst case scenario, you can reinstall Ubuntu. This should fix your issue.
Alternatively, you can upgrade to the latest Ubuntu 16.04 LTS version and that should have some bug fixes that solve your problem.
I recommend using the open source driver that is already installed and in use when you first install Ubuntu. Only change the open source driver to a proprietary one if there are graphical glitches or other problems with your graphics. I have never had problems with the open source graphics drivers.
Finally, make sure that you install all the available software updates since they may fix some issues too.
I recently got a new MacBook Pro running OS X 10.10.2, and I installed Boot2Docker 1.5.0 on it. Aside from Chrome, this is the first program I installed on my new machine. However, when I try to run it, the terminal window opens up for a few seconds, saying boot2docker is up, and then my computer restarts automatically.
I tried to uninstall 1.5.0 and install 1.4.1 (as that is what I was using on my last machine), but I encountered the same problem.
The last thing I see before my laptop restarts is the second image, and the error report my computer shows after the restart is the first image here:

Has anyone every had this problem before, or know how I can address it? Thanks!
Instead of using Boot2Docker, have you considered making a linux virtual machine on your mac? Then you would just run docker on the virtual machine.
This fixed all of the problems I had with boot2docker.
The point of boot2docker is to enable docker to run on your mac. If you use a linux VM you will no longer need boot2docker.
I posted this question in AskDifferent as well, and it turns out there was a problem with OS X Security Update 2015-003 and boot2docker/virtualbox, as per this link: https://github.com/boot2docker/boot2docker/issues/800
Updating my version of VirtualBox remedied the situation.
We're getting into iOS development with MonoTouch. All of our machines are Mac Pros with Windows 7 installed via BootCamp. I'm not crazy about rebooting into OS X just to access the MonoTouch IDE. I'm wondering if it's legal and possible to install OS X on a VM within Windows (if I'm already on Apple hardware, it should be ok, right?). Any other issues with Apple's SDK in a VM (I heard they do some hardware checking of some sort). Thanks in advance for any suggestions!
You can't really run OSX on a VM under windows without going the hacking route. The only way to properly virtualize OSX is to run OSX Server under OSX itself, which is not what you want.
The best option for you is to do what I do: run OSX on your Mac, then use something like VMWare or Parallels to run the Windows you have on your BootCamp as a VM. Works beautifully.
Yup, Eduardo is right, running OSX under non-apple hardware is considered illegal according to apple's license. Moreover, you may run into some issues when creating your developer's account or sumbitting apps.
However, if you still want go the hack way, you can refer to osx86project or just search google for "how to create a hackintosh".
