Hi mates!
First of all apologies if this topic is a duplicated one, but I've been searching through the forum DB for something with the same issue with no success.
ISSUE:
I'm facing some difficulties to power my VMs with Virtualbox Version 6.0.4 r128413 (Qt5.6.3) on MacOS X 10.14.4 (18E226) Mojave. All of them get stuck so I have to reboot twice my laptop.
SCENARIO:
MacbookPro with two external monitors through USB-C to Display Port connectos. LID closed.
TIP:
If I log-in trigger VirtualBox within the LID opened, it works; it just happens if I try to run VirtualBox with the LID closed and working only with external monitors.
This situation has been reported at ticket 18551
thanks!
