FindMyMac says I have no WiFi. Parallels gives me WiFi via a virtual Ethernet network. Do you have Maps running normally? On 10.10.3?
Interesting answer. You question was why the guest cant get your location, even WIFI is enabled - not about 3d support.
This is why I hesitate in upgrading and paying any further. Only Level 2 Customer service know a bit better about the features and still you cannot read about all features and restrictions before buying. They still did not answer whether this is fixed in PD 11, but some posters tell things got worse with the new version.
