I've just updated two computers from Mavericks to Yosemite. The first, a late 2013 27' iMac, wouldn't run my VM from Fusion 5 (fully updated). I found a discussion here that demonstrated this was a common issue, typically solved by updating to Fusion 7, which I did.
The second, a late 2013 Retina 15" MacBook Pro, is running Fusion 6.0.4. It will run my Win 7 Enterprise VM, but there are reproducible graphics anomalies (the screen "flashes" when the VM is running in full screen mode (but not in single window mode). Switching back and forth between integrated and discrete graphics processors (while the VM is shut down, of course), doesn't solve this. Does anyone know if the experience is any better with VMware Fusion 7 (curiously, I didn't have this problem in Mavericks with Fusion 6).
To test, is it possible to run the Fusion 7 evaluation version on my VM, then return to running Fusion 6 if I find the newest version does not fix the anomalies? Any other caveats?
Thanks so much,
Jim
