@jesse94 I am sorry, I have tried it myself and installed windows 10 on my pc and had the same problem.
After some research I found out that this is because VirtualBox uses it’s own virtual graphics card for the virtual machine.
Apparently you can get VB to use your graphics card in stead, but I couldn’t get that to work….Spend all day trying;)
Possibly this only works if you have more than one GPU, so you can assign one to VB.
If you can’t get it to work, you might consider dual booting using Apple’s Boot Camp…
