I have been trying to install Genymotion 2.7.2 the last couple of days on a macbook. I followed various textbooks, but none of them helped.
I installed VirtualBox version 2.0.22, rebooted, and then opened the Genymotion .dmg file. Opening the application from the Applications folder gave me the following error and will ask me to open it again.
I tried to do it differently, but none of them worked. Am I doing something wrong?
