Hi Omar, Should you consider switching from PD, I really would recommend Virtual Box. It's free... and offers about the same features as PD does. It's even faster on some occasions. And it can import PD Virtual Disks. But it's not for everyones use : VRam is limited to 128MB in some VM's... and it's not optimized for some Linux Distros. You can also use VMWare Fusion. As far as I am concerned, since I decided to stop using PD after their despicable marketing (claiming you NEED to have PD10 to run on Yosemite was one ; claiming PD 10 is fully compatible with OsX 10.10 when it was not and solving the problem only after several months...) I switched to VMWare Fusion 7 Pro and, after spending some time to tweak it to my needs, do not regret it. Why ? Simple : same features ad PD10, but 10% CPU usage when idle (where PD 10 uses about 120-150%), faster... Only 2 problems : that annoying keyboard bug (the "@" and "<" are switched...) and the "Unity" bug (it's like Coherence... works much better... but windows do not go to background... making it unusable). Conclusion : none of those virtualization softwares is perfect. The best would be a mix of all 3. But, at least for my own needs, VMWare Fusion is the best option and I'll stick to it... even though, as a good lamb, I bought PD7, PD8, PD9 and PD10... Regards.
