First I had to force the installation of the last tools as descripted here : https://communities.vmware.com/thread/453990?z=6x6tY0
Now it's look stable and only a little issues remain
1°/ With the multi-sceens
I 've 2 screens connected with Thunderbolt adapters (1 VGA and 1 DVI) so that mean I've 3 screen
The principal screen is the one connected on DVI. that one is ok
the second one (VGA) have the apple bar (with fusion) on the top , no way to hide it.
the laptop sceen (macbook pro retina 15), have the Dock bar who is fixed , I can set to auto-hide but that not the ideal.
2°/ the fan issue that start like crazy
the fan issue with chrome browser running in the VM and the power adapter that you need remove is gone!
3°/memory pop'up
I'd few time under windows 8.0 a memory warning who ask me to close IE or Outlook 2013 who seem to be a fake as the VM don't have memory issue...
closing it give few more hours until it came back.
