VMware Fusion running very slow after upgrade to Yosemite

iMac mid 2011 - intel. I upgraded to OS X Yosemite ver 10.10. I am running VMware Fusion Version 7.0.1. My VM is XP with MS Money as the app in question. (I know - old school). The VM is very slow to start and MS Money is so slow it is unusable. I read on the VM site to re-install Yosemite. I did. VM and MS Money started and were very fast - until I shut my iMac down. Upon startup I am getting a progress bar under the gray screen with the Apple. Takes about 30 seconds to boot and to get to a login. When I try to start my VM it is back to being unusable. I feel sure I could reinstall Yosemite and it would be fine again, but I would never be able to shut down - only put it to Sleep mode. It is like something is not "hooking" during the instal. Any ideas?

VMware-OTHER, OS X Yosemite (10.10)

I have the same issue. Everything was fine until I upgraded to 7.0.1. I believe it is connected to the updating the vmware tools.

It is probably re-indexing your disk or something. I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/etrecheck, run it, and paste the results here. EtreCheck is perfectly safe to run, does not ask for your password to install, and is signed with my Apple Developer ID.

Disclaimer: Although EtreCheck is free, there are other links on my site that could give me some form of compensation, financial or otherwise.

PS: You can also just go to Activity Monitor > Show All Processes > Sort by CPU to see which process is taking up your CPU. Of course, if that doesn't reveal anything interesting, you'll have to go back to my first suggestion.

Have you made sure your VM is upgraded and compatible to version of Fusion?

Shut your VM down competely and then go to the VM settings

As mentioned previously, then update your VM Tools

You've bumped into an Apple bug, affecting all hypervisor programs running on Yosemite on mid-2011 iMacs. Apple is aware of the issue.

You can work around it by opening Terminal, and running the following command:

sudo nvram boot-args=debug=0x10

Then, restart your Mac. Fusion should then perform normally.

Cheers,

The bug also was affecting me running Yosemite on a Mid 2012 iMac. Basically Fusion has been useless. I ran the command, rebooted, and it's running the way it's supposed to. Amazing there hasn't been a patch for it yet. Here's the code again. Reboot after you run it:

sudo nvram boot-args=debug=0x10

Thank you so much for posting this. Fusion has been bogging down my entire Mac, to the point where I gave up even using it.

Fyi,

I have a Late 2013 Mac Pro with Yosemite and Fusion 7.1.0, and have been having lots of issues with my VM. This boot-args=debug=0x10 also solved my issue (slow performance in VM, etc..). Made a huge difference. I would recommend reading this post before proceeding: https://communities.vmware.com/thread/493294

After 6 Hours I stumble upon this post wish I have stumbled upon it 5 hours and 55 minutes ago.

Bug also apply to Parallels 9 and 10
