Socratis "* Create a new OSX VM with the 10.11 template. Download the 10.12.4 installer from the AppStore. Use the installation script from [https://forums.virtualbox.org/viewtopic.php?f=22&t=81443 Howto: Create OSX ISO from the OSX Install app] * ''Issue 1:'' the VM will not proceed with the installation, unless USB3 is __specifically__ enabled in the template; the template needs an update (or a new 10.12 template) that makes USB3 mandatory. * '''Issue 2:''' the VM gets stuck on the following: {{{ IOConsoleUsers: gIOScreenLockState 3, hs 0, bs 0, now 0, sm 0x0 }}} Some users have reported this error with previous OSX versions, when the Finder ""kicks"" them out of the system with that message and to the login screen. Will try to find the reference. Please note that an OSX 10.12.3 will update just fine. The same client will fail. Nothing relevant in the logs unfortunately." defect closed other VirtualBox 5.1.18 fixed OSX Server Mac OS X
