VMWare Fusion fails to start VMx on Yosemite.

Just upgraded to Yosemite. When I launch my VMs, I get three pop-ups:


  • Unable to retrieve kernel symbols.
  • Failed to initialize monitor device.
  • Internal error.

Some one previously had same issue on Mountain Lion previously and another user had posted this solution. Is there a similar update for Yosemite?


========

(For Mountain Lion only)

1. Download the update package from http://support.apple.com/kb/DL1686
2. Create an empty mach_kernel file (otherwise the update installer won't work) using Terminal command:

sudo touch /mach_kernel

3. Install the OSXUpd10.8.5Supp.pkg from the downloaded file. It should restore the proper mach_kernel file.

After installing the update (and before restarting) it's possible to verify that the file was installed correctly:

ls -l /mach_kernel

It should show the permissions -rw-r--r--, owner root, group wheel, and file size 8244640 bytes.

===========

To prevent the mach_kernel file from showing up in Finder, run the command:

sudo chflags hidden /mach_kernel

I thought you meant a section within Apple support for VMWare related issues. Yes I have been looking through VMWare forums. This looks like a Yosemite issue. Apple had the same issue previously and did an update with 10.8.5. Hence I am asking for help if someone else has run into this.
