OK I have been googling for a bit time and I don't find anything that works.
I have clicked the install guest additions but nothing and the Auto-Resize Guest Display is always greyed out.
I have changed the com.apple.boot.plist too and in the display settings it doesn't display anything but 1280x1024
I am out of options help please?
And oh my monitor is 1920x1080 and the one on the mac 1280x1024 and the screen is so tight >.<
All answers are appreciated!
