MacOS VMWare Workstation resolution fix

	If you have an issue, when you can't change resolution of the MacOS installed in the VMWare even after VMWare tools has been installed.
	In my case it was not applyable resolution change. I had 1024x768 by default and when I tried to change it to 1600x900, etc. and got
	resolution jump and back to 1024x768

	You may set any supported by your device custom resoultion.

	Just run following command in MacOS Terminal and you will be happy :)
