The boot camp method only uses 1 of the operating systems at the time, if you want to switch back to MAC OS you have to restart and select that one on start up. Because virtual machines can run several operating systems at the same time, they are hardware demanding. Also, there is a setting somewhere that allowed me to start up with MAC OS by default and select the other one only when I needed by pressing a key during start up.Ī virtual machine software runs the second operating system along with the original, you have to assign hardware resources to the virtual machine and those will not be available for the main system. The boot camp method is reversible, if it doesn't work for you, you can 'roll back' to not having 2 operating systems. Some things to consider before you try anything: It worked for me, but I only used it for a month. This software allows you to install a second operating system like Windows to your MAC, and when you start up the computer you can select the one you want to start with. The only way I succeeded to play on a MAC was using a built in software called boot camp. I tried to play on a MAC using a virtual machine software and I could't play, the software crashed every few minutes, it was slow motion sometimes and the camera was a pain.
