Console output:



I noticed I couldn't select "Install for me only":

I tried VBox 4.2.26, failed too.

A few things to try:
1. shutdown your Mac for 10-15 seconds, start your Mac and try and reinstall VirtualBox 4.3.20 again.
2. repair Disk Permissions.
3. create a new user with admin privileges, log in to that user and try to install VirtualBox.
4. if you had a previous version of VirtualBox installed, make sure you use the VirtualBox_Uninstall.tool to uninstall the previous version.
5. if you have an anti-virus program installed try disabling it first.


if none of those work, it is possible your 10.10.1 install is corrupted and you would need to reinstall it.

I went through 1-5, no dice.
I wish i don't have to reinstall my OS. Sorry but is there another way that could tell me why *exactly* the installation failed?

I don't blame you not wanting to reinstall the OS. I can't really tell you why it won't install. I've been using VB for 5+ years and I've never had it not install. I'm running it on 3 different Macs, two with 10.10.1 and one with 10.10.2. You could open the Console and see what error messages are there for VirtualBox.

Start the installation. Before you proceed, go to Window, Installer Log (⌘-L). From the drop-down choose 'Show All Logs'. Proceed with the installation. When the 'Installation Failed' message appears, switch to the log window and either 1) Select all (⌘-A), copy them, paste them in TextEdit, save it, or 2) Save it. Zip the saved log and attach it here.

BTW, it installed just fine on a 10.10.1 VM that I have running around. My gut feeling is that your permissions are wrong someplace.

Thanks socratis,

I've attached the install log.

Are you running ClamAV with Sentry? If so, try disabling Sentry then retry the VB install.

No I don't think so. If I've installed either of them I'd remember.

hmmm, the reason I asked is because one of the errors you are getting is related to ClamAV/Sentry. Did you download VirtualBox directly from the VirtualBox.org download page?

Yes. Can you point out which error excatly?
I don't know if it's relevant, there are things about postflight.

Sorry, my fault. It wasn't an error, was just a similar launchd.

I don't know why you are getting those postflight errors. You did run Disk Utility and repair disk permissions. Maybe someone else may know. I did a Google search for the errors but didn't find anything useful.

Yes I did run disk utilities and fixed disk permissions. Just in case, here are the permission output of my system's /Applications and /tmp folders.

OK, a couple of things:

1. You're using 'zsh' as your shell. At the beginning I thought that this might be the culprit, but I changed my shell to 'zsh' (from the default 'bash') and VirtualBox installed just fine.
2. You said that you uninstalled VirtualBox before installing it. The installer log says otherwise:

   So, please, try to run the 'VirtualBox_Uninstall.tool'. First, make sure that there are no VBox* processes in the Activity monitor (enable 'All processes'). Then open up Terminal (before installing) and type:

   sudo /Volumes/VirtualBox/VirtualBox_Uninstall.tool

   BTW, I did install VirtualBox over an existing VirtualBox just for kicks. It installed fine.
3. You have installed XQuartz. Not sure if there is a conflict there, but since this is an Apple supported project, I highly doubt it. Just mentioning it for completion.
4. Please post the output of the command:

   sudo cat /etc/sudoers

5. Similar problems (with older OSX versions) suggested to enable the root user. I don't believe it personally, but you could try it as a last resort. I do NOT have it enabled, neither on my host or in any of my OSX guests and things work great.

My gut feeling is that #2 is the culprit. I would try to completely uninstall VBox, reboot and start a fresh installation. Otherwise, please mention anything funky that you can think of that you've done to the host to deviate from the typical installation (like zsh and XQuartz).
