Hi, I am trying to set custom video mode for ElCapitan running in VirtualBox as a gues (host machine is Ubuntu Linux - by the way, the whole setup is working great).
I am trying to set CustomVideoMode as to 1920x1800.
In OS X I disabled System Integrity Protection (see guide here: http://anadoxin.org/...tualbox-5.html)
After that I was able to edit file: /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
It looks like this:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Graphics Mode</key> <string>1920x1080x32</string> <key>Kernel Flags</key> <string>"Graphics Mode"="1920x1080x32"</string> </dict> </plist>
Shut down the virtual machine and invoke the following command in Ubuntu host:
VBoxManage setextradata "El_Capitan" "CustomVideoMode1" "1920x1080x32"
After booting the virtual machine with OS X, custom video mode is not working... any idea what is wrong?
