I need to run a VM to run MacOS El Capitan since that's the last version of Safari that has a browser that supports the plugin for my business security camera.
I've installed El Capitan into a virtual box, fire it up and it runs. I can view the security system with Safari.
However, I wanted to add a second screen to my Mac and put the Virtual Box full-screen on that second display. But the VBOX display won't resize from the default 1024x768.
- I have installed the Guest Additions
I have set the display to VBoxVGA and clicked 3D acceleration
I have set the display memory to 128 as suggested in another thread
Host: MacOS High Sierra 10.13.6, 2011 27" iMac 12,2
