MacOS – Using VMware Fusion on Yosemite, how can I prevent crashes with sleep wake failure

macossleep-wakevirtualizationvmware

I am using VMware Fusion 7.1.0 on Mac OS 10.10.1 Yosemite. Every evening, I send my iMac to sleep. The next morning the mac usually sits in login mask – so it has rebooted. After login, I get "sleep wake failure".

How can I mitigate this? Are there any known workarounds?

I had this problem before with Mac OS 10.9 and VMware Fusion 6 but found no workaround. It seems, that with one of the updates of 10.9 the problem went away or was way more seldom.

Best Answer

After talking to VMware support, there are two possible solutions to this problem:

  1. Open your Mac's system preferences, go to Energy Saver and disable the option "Put hard disks to sleep when possible". With that option deactivated, I had no sleep wake failures.

  2. Pause or suspend your virtual machines prior to sending your Mac to sleep.
