VirtualBox Randomly Stopped Working
[virtual-environments wwe I have no idea why, but yesterday when I tried opening VirtualBox to play around, my MacBook Pro told me that it failed to open. Huh? Whatever, let me reboot and try again… Failed to open! Ok, ok – let me google it this. What do I write? “VirtualBox won’t open.” Too general… Oh, I know! Try opening it in Terminal.
cd /Applications/
open VirtualBox.app/
LSOpenURLsWithRole() failed with error -10810 for the file /Applications/VirtualBox.app.
Sweet, at least it gave me something specific to google.
Hmm, seems like everyone thinks things like this could be a permissions problem. I will check to make sure my Mac’s security settings allow apps from sources other than Apple. Yes, it does. Well, let’s look in Terminal:
ls -l | grep VirtualBox
drwxr-xr-x 3 krbn someNumber 102 Feb 13 13:19 VirtualBox.app
Looks like everyone has permission to read and execute… That group looks a little weird, so maybe that’s the problem.
# Attempt 1: there is an admin group; try that
sudo chgrp -R admin VirtualBox.app/
open VirtualBox.app/
LSOpenURLsWithRole() failed with error -10810 for the file /Applications/VirtualBox.app.
# Attempt 2: wheel
sudo chgrp -R wheel VirtualBox.app/
open VirtualBox.app/
LSOpenURLsWithRole() failed with error -10810 for the file /Applications/VirtualBox.app.
# Ok... Change it back and try something else
sudo chgrp -R someNumber VirtualBox.app/
The other solution to similar issues was to reinstall VirtualBox. The first time I installed VirtualBox, I did so manually…but I wonder if you could just use HomeBrew? One quick google later: yes, you can.

🍺 virtualbox was successfully installed!
Nice! Let’s take a look.
open VirtualBox.app
Success! And my Ubuntu VirtualBox is still there: double win!
Side Note: I noticed that the user and group are different when installing with HomeBrew.
ls -l | grep VirtualBox
