In reply to Mukhtar Jafari. That method works much better. Using Version 5.2.26 r128414 (Qt5.6.2) of Virtual Box

With VB 5.1.16 (Linux) none of the proposed solution worked. SIP perventing editing of com.Apple.Boot.plist, in the end I found one solution that works for me (El Capitan and High Sierra VB machines on Debian Linux):

VBoxManage setextradata “” VBoxInternal2/EfiHorizontalResolution 1440
VBoxManage setextradata “” VBoxInternal2/EfiVerticalResolution 900

Mabe that can help someone 🙂
