I'm very happy to say that I have been able to create two different installs of OSX Mountain Lion; one using VirtualBox and the other using VMWare. They both work reasonably well.
My question is around running a particular application: Keynote. I purchased a copy of Keynote but it is unusable on both instances. The slide preview appears on the left bar, but there is no image in the main edit window. Have tried everything I can: 3D graphics are enabled, i've thrown about 128MB of VRAM at it, but no solution.
Has anyone encountered this problem? Any ideas or solutions? I really don't want to buy a Mac just so I can use this app.
